Fossil concentrations are a conspicuous feature of the Monte León Formation (Lower Miocene), providing the opportunity to carry out combined sedimentological and paleontological studies that allow elucidating the processes involved in its genesis and contributing to the knowledge of the depositional paleoenvironment. With these objectives, the stratigraphic, sedimentological, and paleontological features of fossil concentrations containing turritelline gastropods were analyzed in rocks exposed at Restinga Norte (Santa Cruz Province). Four representative samples were extracted, and the taphonomic features of recovered turritelline specimens were analyzed in the laboratory. The textural analysis of the sediments that make up the matrix of the concentrations and the adjacent beds was also carried out. The results allowed them to be classified as "turritelline-dominated assemblages" constituting mixed biogenic-sedimentologic concentrations, with characteristics given by the behavior of the turritellines and their final reworking within the habitat. The abundance of turritellines and the diversity of bryozoans as sclerobionts suggest a habitat of nutrient-rich marine waters, probably associated with upwelling. The good preservation and the high percentage of empty shells—together with the characteristics of the sediment—suggest that their accumulation on the bottom was favored by a low-energy environment. These shells would have been oriented by a unidirectional current that promoted —favored also by a high sedimentary supply—their rapid burial and preservation. The results established that the turritelline-dominated assemblages were formed in a shallow marine shelf in the transition between the retrogradational and progradational facies of the transgressive-regressive cycle proposed for the Monte León Formation in the study area. Las concentraciones fósiles son un rasgo conspicuo de la Formación Monte León (Mioceno Inferior), proveyendo la oportunidad de realizar estudios sedimentológicos y paleontológicos combinados que permitan dilucidar los procesos involucrados en su génesis y contribuir al conocimiento del paleoambiente depositacional. Con estos objetivos, se analizaron los rasgos estratigráficos, sedimentológicos y paleoecológicos de concentraciones fósiles con gasterópodos Turritellinae, presentes en Restinga Norte (provincia de Santa Cruz). Se extrajeron cuatro muestras representativas y se analizaron en laboratorio los rasgos tafonómicos de los especímenes de turritélidos recuperados. Adicionalmente, se realizó el análisis textural de los sedimentos que conforman la matriz de las concentraciones y de los niveles adyacentes. Los resultados permitieron clasificarlas como ensambles dominados por gasterópodos Turritellinae ("turritelline-dominated assemblages"), constituyendo concentraciones mixtas biogénico-sedimentológicas, con características dadas por el comportamiento de los turritélidos y su retrabajo final dentro del hábitat. La abundancia de turritélidos junto con la diversidad de briozoos como esclerobiontes sugieren un hábitat de aguas marinas ricas en nutrientes, probablemente asociado a surgencia de aguas profundas. La buena preservación y el alto porcentaje de conchillas vacías, junto con las características del sedimento sugieren que su acumulación sobre el fondo fue promovida en un ambiente de baja energía. Éstas habrían sido orientadas por una corriente unidireccional promoviendo, en conjunto con un alto aporte sedimentario, su enterramiento rápido y preservación. Los resultados obtenidos sugieren que los ensambles se formaron en una plataforma marina somera, en la transición entre las facies retrogradantes y progradantes del ciclo transgresivo-regresivo propuesto para la Formación Monte León en el área de estudio.

La relación entre los neandertales y el oso cavernario –Ursus spelaeus– durante el Pleistoceno Superior ha sido objeto de controversia debido a que la historiografía tradicional sugería ideas relativas a un posible culto hacia esta especie, junto con otras teorías que respaldan la caza masiva de estos animales. Sin embargo, las pruebas que vinculan una interacción entre el Homo neanderthalensis y el Ursus spelaeus en Europa son limitadas y fragmentarias, y proceden mayormente de Italia, Alemania o Francia, en los alrededores de los Alpes. Hasta la fecha, no se habían encontrado restos de Ursus spelaeus con evidencias de actividad humana en el Paleolítico Medio en la Península Ibérica. No obstante, este artículo presenta y analiza las consecuencias del descubrimiento de una ulna de Ursus spelaeus con marcas de corte, hallada en los niveles musterienses de la cueva del Esquilléu en Cantabria. Este hallazgo, identificado tras un minucioso estudio de la muestra osteológica disponible, representa un nuevo aporte a este debate, ya que amplía el ámbito geográfico y sugiere que las revisiones tafonómicas podrían ser una fuente de nuevas evidencias.

One of the most abundant species of bivalves found on modern beaches and Quaternary deposits in the San Matías Gulf (Argentinian Patagonia, SW Atlantic Ocean) is Glycymeris longior. Its high abundance and broad geographical distribution turn G. longior into a target species for taphonomical studies. Here, we described the taphonomic signature registered on its shells from San Antonio Bay (San Matías Gulf, Río Negro). This study will contribute to future taphonomic comparisons in the SW Atlantic Ocean, as well as in other Quaternary deposits, and provide insight into the spatial variation of the taphonomic processes influenced by the environment. Glycymeris longior valves from the Holocene Punta Delgado deposits showed two taphonomic signatures whose shell assemblages were differentiated by fragmentation, rounding and cementation intensities. Shells from PD2018A and PD2018B (two sampling localities representing similar environments) were subject to continuous and low-energy water flow. Those remained in a low-intensity hydrodynamic sediment-water interface that would favor high shell cementation. On the other hand, shells from PD2016 were also subject to continuous but more energetic water flow. Those would remain in the taphonomic active zone for enough time to confer smooth edges and to be colonized by clionid sponges but not favorable enough for carbonate precipitation. The Punta Delgado site was interpreted as a protected area during the Holocene (last 4200 yrs.), similar to the modern one, but with differences in carbonate precipitation as the product of differences in water flow intensities. Finally, the high mechanical resistance of G. longior shells, together with its abundance and broad geographical distribution, turn this species into a suitable target taxon for further taphonomic and ecologic analyses and comparisons.

En el valle del río Genoa (centro-oeste de Chubut, Argentina), la información sobre las interacciones entre los grupos humanos y los animales es escasa. El hallazgo del sitio arqueológico Cueva de Plaza, en donde se recuperaron restos óseos humanos datados en hace aproximadamente 200 años AP, cuentas vítreas, materiales líticos y el único conjunto arqueofaunístico disponible hasta el momento en el valle, se presentó como una oportunidad para conocer si la asociación entre los restos humanos y los restos faunísticos respondía a un acompañamiento mortuorio o si, como sugería una primera evaluación, se debía únicamente a la actividad de mamíferos carnívoros. Los resultados sugieren que el sitio funcionó como madriguera de zorros con posterioridad a los entierros y ponen de manifiesto la importancia del análisis tafonómico dado que aportan información sobre la presencia de restos de fauna en contextos mortuorios y sobre la intensidad de uso humano del sitio.

In the Genoa river valley (west-central province of Chubut, Argentina), the information on interactions between human groups and animals is scarce. The discovery of Cueva de Plaza archaeological site, where human remains dated 200 years ago, glass beads and the only zooarchaeological assemblage available in the valley were recovered, was a chance to find out if the association between the human and faunal remains responded to funerary offerings or, if as a first evaluation suggested, it was due only to the activity of carnivorous mammals. The results suggest the site functioned as a fox den after the burials and highlight the importance of taphonomic analysis since they provide information on the presence of faunal remains in mortuary contexts and on the intensity of human use of the site.

Se analizan los factores intrínsecos y extrínsecos que controlaron la preservación del saurópodo rebaquisáurido Katepensaurus goicoecheai, procedente de la Formación Bajo Barreal (Grupo Chubut-Cretácico Superior) en el centro-sur de Chubut, cuenca del Golfo San Jorge, Patagonia central, Argentina. Los restos se preservaron en un depósito de desbordamiento no canalizado, de geometría lobulada, de 30 cm de potencia y vinculado a canales fluviales arenosos. Litológicamente está integrado por areniscas gruesas con abundante matriz pelítica y tobácea, que permiten caracterizarlo como un flujo hiperconcentrado. Los elementos recuperados, que corresponden principalmente al esqueleto axial, yacían sobre depósitos pelíticos de una planicie de inundación distal mal drenada y fueron parcialmente cubiertos por el lóbulo de desbordamiento, quedando estructuras expuestas que fueron intensamente erosionadas. Los restos se encontraron incompletos, desarticulados y exhibiendo evidencias de una exposición subaérea prolongada. Fueron poco movilizados por procesos hidráulicos y reorientados de forma normal a la dirección del desbordamiento. La dispersión lateral muestra grupos de huesos producto de entrampamientos hidráulicos causados por los restos de mayor tamaño en la parte central del lóbulo y los más pequeños hacia los laterales acorde a la distribución de energía del depósito. La escasa potencia del desbordamiento no sepultó completamente los restos. Finalmente, un nuevo desbordamiento cubrió completamente los materiales. La acumulación de huesos de Katepensaurus sería una concentración ósea residual y representa una acumulación parautóctona de origen sedimentológico.

En este trabajo se presentan los primeros resultados de un estudio longitudinal iniciado en el año 2016, orientado a analizar las trayectorias tafonómicas que siguen las osamentas de guanaco en el Parque Provincial Ernesto Tornquist (PPET), ubicado en el sector central del Sistema Serrano de Ventania, en el sudoeste de la provincia de Buenos Aires. La muestra está compuesta por siete individuos depositados en distintos ambientes del PPET y en diferente estado de desarticulación, dispersión y enterramiento de sus huesos. Se presenta una descripción detallada de cada caso, describiéndose la metodología de observación y de análisis de datos. Las observaciones efectuadas proporcionan información relevante acerca del impacto de los distintos agentes tanáticos y tafonómicos actualmente operantes en el área de estudio. En particular, los datos obtenidos permiten establecer diferencias en las tasas de descomposición, desarticulación y dispersión de los restos óseos en relación con casos registrados en otras áreas geográficas del país.

A Coleção Etnográfica Awá-Guajá é constituída de uma assembleia faunística de vertebrados proveniente de depósitos de descarte da comunidade Awá-Guajá, localizada no estado do Maranhão. Estudos zoológicos e etnoecológicos com mamíferos, peixes e aves já foram feitos, porém nenhum trabalho envolvendo répteis e anfíbios foi desenvolvido com material proveniente desta coleção. O objetivo deste trabalho é o estudo dos clados de vertebrados mais raros dessa coleção: anuros, serpentes e lagartos. Para essa finalidade foram realizados estudos taxonômicos e tafonômicos e também foi verificada a presença de atividade humana nesses ossos através do estudo de cortes, queimas e quebras. Os espécimes identificados incluem um exemplar de Anura indeterminado, dois indivíduos da espécie de Iguanidae Iguana iguana Linnaeus, 1758 e várias vértebras e costelas de dois gêneros de Boidae, Eunectes e Boa. O Anura e o Iguanidae não possuíam evidência de atividade humana, porém os Boidae apresentaram queima e cortes sugerindo que os espécimes foram manipulados pela comunidade indígena, provavelmente para fins de subsistência.

En el centro-este de la provincia de Santa Fe (departamentos San Jerónimo, La Capital y Las Colonias) la mala preservación ósea constituye un rasgo característico del registro arqueológico regional. Por este motivo, durante la última década se encuentra en desarrollo una investigación orientada al estudio de la diagénesis ósea a diferentes niveles de organización de los huesos. Parte de la misma estuvo centrada en la generación, mediante el uso de sistemas de información geográfica (SIG), de modelos espaciales de preservación ósea diferencial basados en las propiedades de los suelos. Los modelos generados han sido evaluados, y continúan siéndolo en el presente, con información obtenida del análisis de restos óseos recuperados en sitios arqueológicos del área. En este marco, el objetivo de este trabajo es presentar y discutir versiones ampliadas de tales modelos espaciales para un área que incluye la cuenca media e inferior del río Paraná (provincias de Santa Fe, Entre Ríos y Buenos Aires), con el objetivo de proporcionar un marco adecuado para interpretar la variación en las condiciones de preservación ósea en el sur de la región del Litoral argentino.

The AwáGuajá ethnographic collection consists of a faunal assemblage of vertebrates from discard deposits of the AwáGuajá community, located in the state of Maranhão. Zoological and ethnoecological studies were made regarding mammals, fish, and Birds, however no work involving reptiles and amphibians has been developed with material from this collection. The aim in this work was to study the least known vertebrate clades in this collection: frogs, snakes, and lizards. For this purpose, taxonomic and taphonomic studies were carried out and the presence of human activity was verified through the analysis of cut marks and evidence of fire. Identified individuals include a specimen of an indeterminate Anuran, two individuals of Iguanidae, Iguana iguana Linnaeus, 1758, and several vertebrae and ribs from two Boidae genera, Eunectes Wagler, 1830 and Boa Linnaeus, 1758. The anuran and the Iguanidae presented no evidence of human activity, however the Boidae specimen showed burning and cuts suggesting that these animals were manipulated by humans, and such manipulation was probably related to subsistence practices.

The Strophomenata (Rhynchonelliformea brachiopods) are extinct and presumably confined to the Paleozoic. The class comprises the orders Strophomenida, Productida, Orthotetida, and Billingsellida. Three of these four orders have representatives in Brazilian Paleozoic sediments: Strophomenida (Superfamily Strophomenoidea), Orthotetida (Suborder Orthotetidina), and Productida (suborders Chonetidina and Productina). Therefore, we carried out a bibliographic survey and a taphonomic analysis upon the occurrence mode of the class in devonian sedimentary deposits of the Paraná Basin, in the state of Paraná. It was formally recognized Strophomenids representing the orders Productida (Suborder Chonetidina) and Orthotetida (Suborder Orthotetidina), both being present in the Ponta Grossa and São Domingos formations. It was identified six different occurrences suggesting that strophomenids might be a potential bioindicator of bathimetric gradients. [ABSTRACT FROM AUTHOR]

Se analizan los restos óseos de cauquén (Chloephaga sp.) recuperados en el sitio arqueológico a cielo abierto Laguna Las Vegas, cuenca media del río Coyle (Santa Cruz). Se evalúan los hallazgos a la luz de información arqueológica y tafonómica suprarregional, regional y local. La frecuencia de restos (NISP=23), junto con el patrón de partes esqueletarias con evidencias de consumo y las categorías etarias (cuatro individuos adultos y dos juveniles), sugieren que los cauquenes habrían sido obtenidos en proximidades del sitio durante la estación reproductiva y que se habrían transportado a este las partes de mayor rinde económico junto con las unidades anatómicas asociadas. Nuevos fechados radiocarbónicos realizados sobre un resto de cauquén y otro sobre guanaco (Lama guanicoe) sustentan la contemporaneidad aproximada en la depositación de los materiales arqueológicos en el sitio alrededor de 3200 años AP.

The results of the study carried out on cauquén -goose- (Chloephaga sp.) bone remains recovered from the open-air archaeological site of Laguna Las Vegas, middle basin of the Coyle River (Santa Cruz), are presented. We evaluate our findings in the light of supra-regional, regional and local archaeological and taphonomic information. The frequency of remains (NISP= 23), together with age patterning in skeletal parts displaying evidence for consumption (four adults and two juveniles), suggest that the cauquén would have been obtained near the site during the reproductive season, and that the parts with the highest economic yield were subsequently transported to the site together with the associated anatomical units. New radiocarbon dating of one cauquén bone plus another on a guanaco bone (Lama guanicoe) suggest approximate contemporaneity of the archaeological materials at the site, which date to around 3200 years BP.

A lo largo de la vida de los individuos, los huesos experimentan cambios, los cuales pueden dejar marcas en el tejido óseo que resultan de interés para los estudios bioarqueológicos. Dichos cambios se manifiestan en una serie de rasgos óseos que se constituyen como una potencial línea de evidencia para indagar sobre el estilo de vida de las poblaciones del pasado. Sin embargo, a la hora de analizar tales alteraciones, es necesario tener en cuenta que existe una amplia variedad de agentes y procesos tafonómicos que pueden imitar rasgos morfológicos producidos por condiciones patológicas, así como también de naturaleza no patológica. Se trata de las denominadas alteraciones pseudopatológicas, y su origen puede deberse a factores tanto naturales como antrópicos, pasados y actuales. En este trabajo se indagará en un tipo de alteración particular, la porosidad, a los fines de establecer ciertos criterios para reconocer la naturaleza de esta lesión con el objetivo de contribuir a su correcta identificación y poder llevar adelante un diagnóstico diferencial.

The role of plant foods during the fluted-point period (FPP) of North America is contested. Central to this debate is whether the scarcity of FPP macrobotanical materials stems from poor preservation of archaeological features and the macrobotanical remains they might contain or from the limited use of plants during the FPP. Employing summed probability distributions of radiocarbon date frequencies in northeastern North America, we find that FPP hearths are as common as expected, given the small number of well-dated FPP sites in the region. A second comparison shows that northeastern FPP hearths contain macrobotanical remains at a higher frequency than hearths from a region with better preservation and where small seeds formed a part of the diet. The macrobotanical materials so far recovered from FPP hearths in the Northeast show that plant foods contributed to diets during the FPP but that the plant diet breadth was relatively narrow, consistent with a specialized caribou hunting lifeway.

El Abrigo de La Viña es uno de los yacimientos claves para el estudio del Paleolítico Superior de la región cantábrica, debido a su larga secuencia arqueológica y a sus grafías parietales pre-magdalenienses. En este trabajo se presenta el estudio arqueozoológico y tafonómico de los restos faunísticos hallados en los niveles solutrenses del Sector Occidental. Los resultados muestran una explotación preferente del ciervo complementado con otras especies como grandes bóvidos, caballos y cápridos, sin evidenciar una especialización cinegética sobre ninguno de los taxones. El análisis tafonómico revela que los grupos humanos fueron los principales responsables de la acumulación ósea y aprovecharon de modo intensivo las carcasas. El método bayesiano, aplicado a los perfiles esqueléticos, sugiere que las carcasas de ciervo y cabra se trasladaron completas al yacimiento, en consonancia con el estudio de las áreas de captación de recursos bióticos y abióticos, que muestra una explotación del entorno más inmediato del abrigo.

El estudio de los patrones de remodelado óseo en el esqueleto facial es de interés en estudios arqueológicos y bioarqueológicos, ya que brindan información sobre los procesos de crecimiento y el efecto de la dureza de la dieta sobre las cargas masticatorias, entre otros. Sin embargo, las alteraciones post-depositacionales a las que están expuestos los restos pueden afectar la superficie cortical del hueso y, en consecuencia, dificultar la identificación de los rasgos histológicos asociados al remodelado óseo. Particularmente, uno de los procesos que pueden alterar la superficie cortical en contextos arqueológicos es la meteorización. El objetivo del presente trabajo es evaluar el efecto de la meteorización en la identificación del remodelado óseo en el esqueleto facial a partir del análisis de individuos subadultos de dos muestras procedentes del Noroeste Argentino y Patagonia. Se evaluó el grado de asociación entre el estadio de meteorización del esqueleto facial y el porcentaje de remodelado óseo relevado. Se observó mayor incidencia de meteorización en la muestra de Patagonia, principalmente en individuos de menor edad, asociada a un mayor porcentaje de datos de remodelado. Por el contrario, los individuos del NOA presentaron mejor preservación de las superficies, principalmente a menor edad, pero menor porcentaje de datos de remodelado óseo. Los resultados obtenidos indican la necesidad de profundizar los análisis que abordan el impacto de los procesos post-depositacionales en la reconstrucción de los patrones de remodelado óseo.

Las prácticas ganaderas han jugado un papel importante en la organización socioeconómica de las sociedades mineras. Este trabajo presenta los resultados del análisis arqueozoológico y tafonómico de los restos de fauna recuperados en la Mina16 en Gavà (Barcelona). Los análisis de los restos de fauna se utilizaron para determinar la importancia ganadera en las prácticas de subsistencia, el origen y la dinámica de depósito del conjunto faunístico en el relleno de la Mina16. Las actividades mineras en Gavà no reemplazaron la producción especializada de subsistencia, sino que la complementaron. Los resultados sugieren que los restos de fauna encontrados en las minas fueron residuos de producción y consumo, lo que proporciona evidencia nueva y complementaria del asentamiento asociado con las estructuras mineras.

Los entierros humanos del sitio Río Bote 1 constituyen una nueva oportunidad para estudiar el registro mortuorio en la cuenca superior del río Santa Cruz entre ca. 3800 y 3600 años AP. El objetivo de este trabajo es identificar los procesos de formación de los entierros humanos que se encontraron en dicho sitio arqueológico a partir del análisis tafonómico de sus restos óseos. Los resultados obtenidos apuntan a que los entierros presentan una preservación diferencial en relación con la edad del individuo inhumado y su posición dentro del sustrato sedimentológico. Los ciclos de incorporación de fluidos y la transformación del abrigo rocoso fueron factores fundamentales sobre los procesos diagenéticos de los entierros.

En este trabajo se exponen los resultados obtenidos de los análisis realizados sobre los restos de fauna menor (

Os aspectos icnológicos relacionados a substrato ósseo da Formação Solimões (Mioceno superior da Bacia do Acre) ainda são pouco conhecidos. Um estudo tafonômico recente dos fósseis desta unidade disponíveis no acervo do Museu de Ciências da Terra da Companhia de Pesquisa em Recursos Minerais (MCT/CPRM) revelou uma vértebra de Crocodylia com uma feição de origem biogênica. Este trabalho descreve tal feição e estabelece uma caracterização icnotaxonômica do traço fóssil, associando-o a um possível produtor. A icnoespécie Nihilichnus nihilicus é reportada pela primeira vez para a Formação Solimões, correspondendo a um traço fóssil observado em vértebra dorsal posterior de um Crocodylia de grande porte. Purussaurus é o provável produtor do traço observado, não sendo possível discernir se a gênese do icnofóssil está relacionada a predação ou necrofagia.

Recent fieldwork in the state of Mato Grosso made it possible to find new specimens of trilobites, among them: Metacryphaeus australis, Metacryphaeus sp. and a homalonotide. Taphonomically, it was possible to observe that there are two patterns of conservation, one of which is where the specimens are complete, related to a rapid burial event; and another pattern of preservation where paleoenvironmental conditions provided disarticulation after death. These new findings, as well as their taphonomic interpretations, open possibilities to work on biostratigraphic correlations, in addition to paleobiogeographic assessments for trilobites in South America.

The northeastern region of the state of Paraná, Brazil, is still little known in its paleontological and stratigraphic aspects. This work focused on Devonian outcrops located in Arapoti and Piraí do Sul, and aimed at the recognition of sedimentary facies and the definition of taphofacies, with the intention of paleoenvironmental interpretation and stratigraphic correlation. Three different facies were identified, representing shoreface to offshore environments, and also three taphofacies were defined: T1 characterizes the most proximal and destructive environments, T2 represents lower shoreface environments and T3, originated offshore. The base of the section is correlated to the early Devonian, Ponta Grossa Formation, Siluro-Devonian Sequence (Neopraguian-Eoemsian) due to the visible contact with sandstones of the Furnas Formation, and the top, due to the presence of microfossils, is positioned in the São Domingos Formation, Devonian Sequence I (Neoemsian-Eoeifelian).

In this paper we characterize pecopterids found in deposits of the Passa Dois Group (Upper Permian of the Paraná Basin) in a new outcrop, on the side of the BR-153 road, located at the municipality of Aceguá, Rio Grande do Sul State, Brazil. Pecopterids are common in the Permian paleophytogeogragic realms, signaling interglacial phases of the Late Paleozoic. Pecopteris are one of the floral elements of the Permian Glossopteris flora and become extinct in the Permo-Triassic boundary. Mudstone strata levels bearing phytofossils with different preservation qualities allowed the recognition of Pecopteris sp. and cf. Scolecopteris sp. floral elements. Taphonomic and depositional processes that conditioned the presercation of phytofossils are suggested accordingly the specimens described. Phytofossil specimen described support and highlight polymorphic nature of Gondwanan pecopterids. These new findings demonstrate potential for further paleobotanical studies in the upper portion of the Passa Dois Group and strength the notion of Permian strata for the Teresina Formation.

This article addresses the study of an indigenous burial at Mina Mountain (Lanzarote), dating from cal A.D. 1300 to 1402. Pre-European funerary contexts in Lanzarote are scarce, resulting in a particular historical situation for a population that lived on the island for at least 1,400 years, whose dead people and burial sites are virtually unknown. We analyze the available data on mortuary practices of the native population, adding a new example to the limited existing evidence. This is the first archaeological study carried out on the island that focuses on a funerary context, providing clear evidence for canine scavenging on a corpse placed in a pit and the subsequent rearrangement of the disarticulated skeletal remains in a secondary hollow. The study advances bioanthropological description and specific taphonomic data of bone modifications as evidence of the events that took place at the site, providing data to interpret this singular burial. In addition, the chronological framework, together with the references of the narrative sources describing the Franco-Norman conquest of the island in 1402, allows us to propose a potential scenario explaining this unique site.

Resumo Desde o início dos estudos sobre a formação do registro arqueológico, vem se buscando ferramentas para acessar os processos de deposição e de transformação desses locais ao longo do tempo. A experimentação com o objetivo de reproduzir contextos arqueológicos, apesar de amplamente utilizada em algumas regiões, ainda foi pouco explorada em contextos amazônicos, que possuem processos tafonômicos específicos. Este trabalho visa, através da experimentação, testar algumas das variáveis estabelecidas em regiões temperadas para movimentação e preservação de material ósseo, buscando entender tanto suas validades para a Amazônia quanto as dinâmicas específicas dos microcontextos. Foram utilizados galinhas e materiais de acompanhamento para estruturar os ensaios, enterrados e deixados em superfície. Os resultados apontam para fatores extrínsecos conhecidos, como a presença de raízes de plantas, o contato direto ou não com o solo e outros, mas cujas dinâmicas em contexto amazônico parecem amplificadas. Ao final, propomos que as observações obtidas podem ser significativas para a arqueologia amazônica como um todo.

Taphonomic studies were carried out at Laguna Flecha Negra locality (Bahía Laura Complex, Middle-Late Jurassic), Santa Cruz Province, Argentina. Sedimentary facies and preservational styles were defined to recognize plant taphofacies in the studied sequence. Eleven taphofacies were identified and plant sources within a volcanic and geothermal system are proposed. Plant remains are of autochthonous to para-autochthonous origin and best preservation was found in distal facies of siliceous hot spring (sinter) systems. Lateral and vertical taphonomic differences were found in the studied sequence. These are due to changes in the sedimentary input and distance to the geothermal fluids. Results enable the reconstruction of the depositional history of this region of the Deseado Massif geological Province. We infer formation of a hot-spring (sinter) system that was subsequently destroyed by a phreatic eruption process at the margin of an andesitic effusive dome in partially reworked fall pyroclastic subfacies. After the destruction of the geothermal system, a fluvial and lacustrine epiclastic subfacies developed preserving a plant community typical of the Middle-Late Jurassic of Gondwana. Later, volcanic activity produced pyroclastic subfacies, with thick ash-fall and flow deposits from different sources and separated by a time gap that promoted fossilization of an in situ forest. Taphonomic studies of these plant communities allowed reconstruction of a chain of geological events and how these processes have influenced the preservation of a Jurassic flora from Patagonia, thus contributing to an understanding of the paleoecology of the Deseado Massif geological province.

INTERNATIONAL LAW ENFORCEMENT AGENCIES ADOPT A STANDARD PROCEDURE TO ANALYSE A CRIME SCENE, BEGINNING WITH A LANDSCAPE MACROSCOPIC STUDY (E.G., REMOTE SENSING) TILL A MICROSCOPIC EVIDENCE ANALYSIS (E.G., ARCHAEOLOGICAL STRATIGRAPHY) FOLLOWING INTERMEDIATE STEPS SUCH AS GEOPHYSICS, FIELDWALKING, AND TAPHONOMY.

Se presenta el análisis zooarqueológico y tafonómico del sitio Álvarez 4, un alero emplazado en la cuenca media del río Limay en el noroeste de Patagonia, Río Negro, Argentina. Los restos faunísticos provienen del Período I (1100 ± 70 AP), del Período II (210 ± 90 AP), de la cuadrícula C3 (perturbada antrópicamente) y de la Capa Superficial (210 ± 90 AP). Se determinó una incidencia baja de procesos postdepositacionales. Se registró la acción de otros procesos tafonómicos como perturbación sedimentaria por causas antrópicas y posible migración de huesos. Una parte destacable de los restos ingresaron al sitio como descarte de alimentación humana y de la confección de instrumentos. Lama guanicoe fue el taxón más explotado en el sitio, aunque con algunas variaciones a lo largo de la secuencia. Se registró la explotación de Leopardus sp. en C3. En el Período I se utilizó Diplodon chilensis, Lama guanicoe, Conepatus chinga y Chaetophractus villosus. La incorporación de varios taxones (Rhea pennata, Lycalopex gymnocercus, Zaedyus pichiy, Lagidium viscacia y Caviinae indeterminado) en el Período II sugiere una ampliación de la dieta. Las especies exóticas halladas en la Capa Superficial, Ovis orientalis aries y Lepus europaeus, no formaron parte de la economía humana.

In January 2019 there was a partial collapse of the «E» wing of the first body of funerary niches of the Central Cemetery of Montevideo, affecting 64 niches containing burials from the mid-nineteenth century to the present. The archaeological rescue work of the collapsed sector resulted in the recovery of intact or slightly altered funerary structures and in the extraction of displaced or isolated remains that were analyzed separately and are the object of this work. The remains were studied in order to determine the number of individuals, sex and age structure, and the effect of the collapse and the recovery methodology on the representation of bone elements. Three specific studies were carried out on subsets of the sample: taphonomy of adult individuals, age and sex structure of subadults, and osteobiography of two individuals. Although the inferences made should be taken with caution due to the fragmentary nature of the analyzed remains, it is concluded that the remains have an important potential as a source of knowledge of postdepositional factors, demography and living conditions of the high socioeconomic status population of the city of Montevideo in the second half of the 19th century and first half of the 20th century.

The remains of marine molluscs found in the recent excavations (2012-2019) of the Mallorcan Iron Age (Talayotic and Balearic period) Necropolis of Son Real are described here. This cemetery represents a unique funerary space in Mallorca, since the burials were carried out in tombs that miniaturize buildings of high social significance, such as talayots or navetes. The study of these remains has focused on taphonomic aspects, apart from the taxonomic and biometric, and it is complemented by the report published in the doctoral thesis of one of us in 1998. One of the most outstanding results of the analysis of the different contexts is the scarce presence of marine molluscs in the deposits, especially when the proximity to the sea is taken into account. This contrasts with the numerous elements found in two very close and linked sites, such as the necropolis of Illot des Porros and the sanctuary of Punta des Patró. Despite this, more than their number, the most outstanding feature is related to the specific location of the remains themselves. Some of them clearly appear in interment contexts and they are possibly linked to funerary rituals, similarly to the interpretation given to the scarce remains of vertebrates found.
