Abstract

Competency-based learning have been proved to be an effective learning method characterized by developing and applying specific skills that can then be used to obtain the required knowledge. Thus, the process of teaching and learning should be undertaken by combining active-learning and collaboration to help to retain the knowledge. Therefore, a multidisciplinary vision in which each professional contribute with a specific topic would be necessary. Few topics of the Earth and Life Sciences, taught in Spanish education, show the interrelations between Geology and Biology. On the other hand, Spanish students generally value Biology better than Geology, due to the combination of many factors such as the little presence of Geology in the curricula, the scarce relationship between these two sciences, the extremely theoretical classes or the greater knowledge that students have of job opportunities in the field of Biology. In this paper we revise the curricula of Spanish Bachelors degree (students from 16 to 18 years old) to find issues that can present an interdisciplinary vision related to Crystallography and Mineralogy, in which current learning is non integrated nor motivating as many studies show. We propose some contents that can be included in relation to the human body biominerals (bones, teeth,…), their mineralogical characteristics and their anatomical and physiological functions. The main objectives are to use the good valuation of anatomical topics to introduce lesser-known concepts of Crystallography and Mineralogy, and at the same time to motivate the students to study and value these Geology fields emphasizing their importance in emerging research fields and new work opportunities such as Medical Geology, Depto. de Mineralogía y Petrología, Fac. de Ciencias Geológicas, TRUE, pub

Abstract

Among the initiatives that seek to promote earth sciences among young people are the Geology Olympics. This article analyses the perceptions of previous training among eleven of the winners of the first ten Geology Olympics held in Spain. This study also investigates the factors that have influenced young people to choose their university careers and their perceptions of the learning that participation in the Olympics has meant for them. The results indicate that the theoretical training they have received in the first cycle of secondary education has been limited and that practical content and geological field trips are practically nonexistent. Thus, only the good work of teachers has motivated them to take optional subjects such as geology and participate in activities such as the Olympics, which are a decisive factor in choosing university degree in Geology. Every participant changed their perspective of geology and its professionals after their participation in the Olympics. One of the aspects to consider is that more integrated and practical knowledge should be imparted in teacher training master’s degree programs, as well as in providing more didactic instruments to future teachers so that they can implement better geological training for our young people., Universidad de Alcalá, Ministerio de Educación y Formación Profesional, Depto. de Geodinámica, Estratigrafía y Paleontología, Fac. de Ciencias Geológicas, TRUE, pub

Abstract

Methodologies that analyse the colouration and external appearance of extant species are very useful tools when facing one of the greatest challenges in the palaeoartistic reconstructions of extinct fauna: inferring the colour patterns. Earlier works have applied this methodology, for example, in the reconstruction of the Miocene bovid Tethytragus, proving that the maximum likelihood (ML) analysis to infer ancestral states has promising potential. This study offers a proposal for the reconstruction of the external appearance of Heteroprox moralesi Azanza 1989, an early cervid of the Middle Miocene present in several fossil sites of Central Spain. For the reconstruction of the external appearance, the colour patterns of all the extant species of the family Cervidae were studied with the method of ML analysis, as well as recent works about their phylogeny. The results show the most probable basal colour pattern of the cervids: dark shades on the limbs, dorsal section, and head of the animal, and, in contrast, lighter colours on the neck and perianal region. This basal pattern can be used as a basis for reconstructing colouration and to hypothesise about the external appearance of extinct taxa. Furthermore, the inferred forest habitat of H. moralesi has been taken into consideration in order to adjust the colour pattern, comparing the final results of the analysis performed in this study with that of the pattern observed in extant forest deer as well as with previous works employing this methodology.

Abstract

RESUMEN: El análisis de terminología explícita relacionada con la paleontología y la evolución en los currículos educativos estatales desde 1970 a 2020 refleja la escasez o incluso la ausencia de referencias, caracterizadas por un tratamiento poco homogéneo, siendo la LOMCE el marco que recoge mayor variedad de términos. Destaca la omisión de la palabra “paleontología” en todas las leyes posteriores a la Ley General de Educación (1970). Se observa un aumento de la importancia en términos relacionados con los paleoambientes o los paleoclimas, en parte acorde con la propia evolución social y legislativa que da mayor importancia a la sostenibilidad y la protección del medio natural. Finalmente, se incide en la necesidad de incluir nociones sobre la importancia de esta ciencia y dar una visión sistémica de la evolución en las asignaturas relacionadas con la Biología y la Geología en Educación Secundaria. RESUMO: A análise da terminologia explícita relacionada com a paleontologia e a evolução dos currículos educacionais do estado de 1970 a 2020 reflecte a escassez, ou mesmo a ausência, de referências, caracterizada por um tratamento não homogéneo, sendo a Ley Orgánica para la Mejora de la Calidad Educativa (LOMCE) o enquadramento legar que inclui a maior variedade em termos. Destaca-se a omissão da palavra "paleontologia" em todas as leis posteriores à Ley General de Educación (1970). Observa-se um incremento na importância dada aos termos relacionados com os paleoambientes ou os paleoclimas. Isto está relacionado com a recente evolução social e legislativa que dá maior importância à sustentabilidade e à protecção do ambiente. Finalmente, é enfatizada a necessidade de incluir noções sobre a importancia desta ciência e de dar uma visão sistémica da Evolução em disciplinas relacionados com a Biologia e Geologia no Ensino Secundário. ABSTRACT: The analysis of explicit terminology related to Paleontology and Evolution in state educational curricula from 1970 to 2020 reflects the scarcity or even the absence of references, characterized by a not very homogeneous treatment, being the LOMCE the framework that includes the greatest variety of terms. The omission of the word "paleontology" in all laws subsequent to the General Education Law (1970) stands out. There is an increase in the importance of terms related to paleoenvironments or paleoclimatespartly in line with the social and legislative evolution itself, which gives greater importance to the sustainability and protection of the natural environment. Finally, the need to include notions about the importance of this science and to give a systemic vision of evolution in subjects related to Biology and Geology in Secondary Educationis emphasized. info:eu-repo/semantics/publishedVersion

Abstract

RESUMEN: En este trabajo se presenta una propuesta de reconstrucción esquelética del cérvido basal Heteroprox moralesi (Aragoniense medio, Mioceno medio) que sirva de base a futuros trabajos de la reconstrucción muscular y de la apariencia externa de esta especie y de otras especies de cérvidos miocenos. Algunos restos asignados a esta especie han sido hallados en varios yacimientos madrileños, si bien gran parte de los fósiles conocidos asignados a este taxón aparecen muy fragmentados y con muy pocos elementos postcraneales publicados, lo que dificulta en gran medida su reconstrucción esquelética. Por lo tanto, la reconstrucción propuesta en este trabajo se basa en anatomía comparada con otras especies de cérvidos tanto extintas como actuales, además de las evidencias más recientes en cuanto a su clasificación filogenética. RESUMO: Este trabalho apresenta uma proposta para a reconstrução esquelética do cérvido basal Heteroprox moralesi (Aragoniano médio, Miocénico médio) que será utilizada como base para futuros trabalhos de reconstrução muscular e aparência externa desta espécie e de outras espécies de cérvidos do Miocénico. Alguns vestígios atribuídos a esta espécie foram encontrados em vários sítios de Madrid, embora uma grande parte dos fósseis conhecidos e referidos a este táxon sejam incompletos e com poucos elementos pós-cranianos publicados, o que torna a sua reconstrução esquelética muito difícil. Portanto, a reconstrução proposta neste trabalho é baseada na anatomia comparada com outras espécies de cérvidos, extintas e atuais, bem como nas propostas mais recentes relativas à sua classificação filogenética. ABSTRACT: This work presents a proposal for a skeletal reconstruction of the basally branching cervid Heteroprox moralesi of the middle Aragonian (middle Miocene) that will serve as the basis for future works about muscle reconstruction and external appearance. Some remains assigned to this species have been found at several fossil sites from Madrid (Spain), although a large part of the known fossils assigned to this taxon are very fragmented and with few published postcranial elements, which makes skeletal reconstruction very difficult. Therefore, the reconstruction presented in this paper is based on compared anatomy with extinct and extant cervid species, in addition to the most recent evidence of their phylogenetic classification. In this way, a speculative reconstruction is proposed for Heteroprox moralesi that can serve as reference for the reconstruction of other Miocene cervids. info:eu-repo/semantics/publishedVersion

Abstract

El evento de enfriamiento global del Mioceno medio ha sido descrito, a escala local, en el centro de la Península Ibérica (Cuenca de Madrid). Algunos yacimientos paleontológicos como Somosaguas (14,1 Ma) y Cerro de los Batallones (9 Ma) han sido ampliamente estudiados. Además, otros yacimientos situados temporalmente entre ellos, como los yacimientos de Paracuellos del Jarama, tienen un gran potencial de estudio. En este trabajo se han caracterizado los paleoambientes de los yacimientos de Paracuellos-5 (13,7 Ma) y Paracuellos-3 (12,8 Ma), ambos pertenecientes al Mioceno medio, para dar una visión más completa de las características paleoambientales de este intervalo. Se emplearon seis modelos cuantitativos de inferencia climática basados en la estructura de pesos corporales de los mamíferos para estimar la temperatura y la precipitación en el área de estudio. Las inferencias ambientales obtenidas permiten exponer la hipótesis de que en un intervalo de tiempo menor a 1 millón de años, el ambiente existente en Paracuellos tuvo una tendencia hacia el aumento de la humedad, aún manteniéndose como un ambiente de extrema aridez, The middle Miocene global cooling event has been described at a local scale in central Spain (Madrid Basin). There are well-studied fossil sites as Somosaguas (14.1 Ma) and Cerro de los Batallones (9 Ma). In addition, other fossil sites situated temporarily between them, such as the Paracuellos del Jarama fossil sites have a great potential. In this work, the palaeoenvironments of Paracuellos-5(13.7 Ma) and Paracuellos-3 (12.8 Ma) sites, both from the middle Miocene, have been characterized to show a more complete view of the environmental characteristics prevailing during this period. Six quantitative climatic inference models based on body-size structure of mammal faunas have been used to estimate temperature and precipitation of the study area. The obtained environmental inferences allow formulating the hypothesis that, in a time interval of less than 1 million years, the environment of Paracuellos experienced a trend through slightly more humid conditions, remaining as an extremely arid environment

Abstract

Se describen los resultados de los análisis espectroscópicos, correspondientes al rango espectral infrarrojo medio, de muestras de la fracción arcillosa de los ocho niveles estratigráficos descritos en el yacimiento paleontológico de Húmera (oeste de la ciudad de Madrid). Esta zona muestra un interés especial por las características tafonómicas observadas en estudios previos, que indican procesos de diagénesis temprana y plantean incógnitas sobre los intercambios iónicos entre las fases minerales de los sedimentos y los fósiles que albergan. Por lo tanto, los estudios mineralógicos y geoquímicos son importantes para esclarecer los procesos de transformación entre fases minerales y fósiles. Se observa que los sedimentos están formados por filosilicatos, cuarzo y feldespatos, con menores cantidades de calcita. Se distinguen diferentes minerales de la arcilla, entre los que destacan diversas fases de la serie de las esmectitas dioctaédricas (montmorillonita-beidellita), mostrando diferentes cationes en posiciones octaédricas. También están presentes la caolinita y las micas (dioctaédricas y trioctaédricas). La coexistencia de diferentes tipos de esmectitas podría indicar diversos procesos de transformación a partir de minerales preexistentes (heredados de áreas fuente) o la presencia de interestratificados. Estos resultados concuerdan con medios de abanicos aluviales y lacustres en un ambiente con estacionalidad hídrica contrastada, The results of the spectroscopic analyzes, corresponding to the mid-infrared spectral range, of samples of the clay fraction obtained from the eight stratigraphic levels described in the paleontological site of Húmera (west of Madrid city) are described. This area shows a special interest because of the taphonomic characteristics observed in previous studies, which indicate processes of early diagenesis and pose unknowns about the ionic exchanges between the mineral phases of the sediments and the fossils they house. Therefore, mineralogical and geochemical studies are important to establish and clarify the transformation processes between mineral phases and fossils. It is observed that the sediments are formed by phyllosilicates, quartz and feldspars, as well as minor amounts of calcite. Several clay minerals are distinguished, among which various phases of the dioctahedral smectites series (montmorillonite-beidellite) stand out, showing different cations in octahedral positions. Kaolinite and micas (di and trioctahedral) are also present. The coexistence of different types of smectites could indicate various transformation processes from pre-existing minerals (inherited from the source area) or the presence of mixed-layer minerals. These results are in accordance with sedimentary media of alluvial fans and lakes, in an environment with contrasted hydric seasonality

Abstract

Este estudio indaga si el estudiantado de un máster está preparado para organizar una actividad ocio-formativa dirigida a público general, y evalúa la propia actividad como método divulgativo de la paleontología. Para ello se han analizado los resultados de la implementación de un Escape Room paleontológico, organizada por un grupo de estudiantes del Máster Interuniversitario en Paleontología Avanzada de la Universidad Complutense de Madrid durante la XVIII Semana de la Ciencia de Madrid, y se presentan las fases y el desarrollo de dicho Escape Room, que justifican su interés educativo. Los estudiantes organizadores manifestaron un alto grado de compromiso y satisfacción alegando como motivación a participar su interés por la ciencia y por aprender a realizar una divulgación científica eficaz. Esta actividad ha supuesto para el estudiantado organizador una aplicación de lo aprendido en el aula y les ha permitido mejorar competencias que les serán de utilidad a largo plazo. La inmensa mayoría de los asistentes valoraron positivamente la actividad y consideraron que habían aprendido con ella. Conocer como sociedad el pasado de la Tierra, así como nuestros propios orígenes, es la llave para inferir nuestro futuro y, al menos en parte, valorar, preservar y proteger el patrimonio natural que nos rodea., This study aims to answer the question of whether the students of a master’s degree are qualified to organise a leisure-educational activity aimed at high school students and the general public, and assesses whether said activity works as an educational tool for palaeontology outreach. For this, the results obtained from a palaeontology-themed escape room implemented by a group of students of the master’s degree in Advanced Palaeontology at the Complutense University of Madrid during the XVIII Week of Science in Madrid have been analysed and the phases and development of the escape room are presented. Contributing students expressed a high degree of commitment and satisfaction, claiming as the main incentive to participate their interest in science and learning to achieve effective scientific dissemination. This activity has meant for the organizing students an application of what they have learned in the classroom and has allowed them to improve skills that will be useful in the long term. The evaluation of the experience by the attendees was also very positive. The great majority recommended the activity and considered that they had learned from it. Knowing as a society the past of the Earth and life, as well as our own origins, is the key to infer our future and, at least in part, to value the natural heritage that surrounds us and therefore to preserve and protect it., Fundación madri+d, Universidad Complutense de Madrid, Depto. de Geodinámica, Estratigrafía y Paleontología, Fac. de Ciencias Geológicas, TRUE, pub

Abstract

Se describen los resultados de los análisis espectroscópicos, co- rrespondientes al rango espectral infrarrojo medio, de muestras de la fracción arcillosa de los ocho niveles estratigráficos descritos en el yacimiento paleontológico de Húmera (oeste de la ciudad de Madrid). Esta zona muestra un interés especial por las características tafonó- micas observadas en estudios previos, que indican procesos de diagé- nesis temprana y plantean incógnitas sobre los intercambios iónicos entre las fases minerales de los sedimentos y los fósiles que albergan. Por lo tanto, los estudios mineralógicos y geoquímicos son importan- tes para esclarecer los procesos de transformación entre fases mi- nerales y fósiles. Se observa que los sedimentos están formados por filosilicatos, cuarzo y feldespatos, con menores cantidades de calcita.Se distinguen diferentes minerales de la arcilla, entre los que destacan diversas fases de la serie de las esmectitas dioctaédricas (montmorillo- nita-beidellita), mostrando diferentes cationes en posiciones octaédri- cas. También están presentes la caolinita y las micas (dioctaédricas y trioctaédricas). La coexistencia de diferentes tipos de esmectitas podría indicar diversos procesos de transformación a partir de minerales pre- existentes (heredados de áreas fuente) o la presencia de interestratifi- cados. Estos resultados concuerdan con medios de abanicos aluviales y lacustres en un ambiente con estacionalidad hídrica contrastada., The results of the spectroscopic analyzes, corresponding to the mid-infrared spectral range, of samples of the clay fraction obtained from the eight stratigraphic levels described in the paleontological site of Húmera (west of Madrid city) are described. This area shows a special interest because of the taphonomic characteristics observed in previous studies, which indicate processes of early diagenesis and pose unknowns about the ionic exchanges between the mineral phases of the sediments and the fossils they house. Therefore, mineralogical and geochemical studies are important to establish and clarify the trans- formation processes between mineral phases and fossils. It is observed that the sediments are formed by phyllosilicates, quartz and feldspars, as well as minor amounts of calcite. Several clay minerals are distin- guished, among which various phases of the dioctahedral smectites series (montmorillonite-beidellite) stand out, showing different cations in octahedral positions. Kaolinite and micas (di and trioctahedral) are also present. The coexistence of different types of smectites could indi- cate various transformation processes from pre-existing minerals (in- herited from the source area) or the presence of mixed-layer minerals. These results are in accordance with sedimentary media of alluvial fans and lakes, in an environment with contrasted hydric seasonality., Depto. de Geodinámica, Estratigrafía y Paleontología, Fac. de Ciencias Geológicas, TRUE, pub

Abstract

This study addresses the need to include notions about the importance of natural heritage in subjects related to Biology and Geology in Secondary Education. For this, it has been analyzed the explicit presence of words related to paleontological, geological and natural heritage within all the laws implemented since 1970 in the educational curricula at the state level in Spain. The results reflect the scarcity of references to these concepts and point out that they are not always homogeneously treated. Conversely, in all the educational laws, mentions of cultural heritage stand out clearly, both in its historical and artistic denotations. Finally, a thoughtful approach and suggestions are presented as a proposal to discuss the expansion of these concepts and for their greater integration in matters related to natural sciences. These suggestions have meaning in the context of a slow but continuous educational change towards positions favorable to sustainability, in which equitable inclusive education in close contact with nature should be the fundamental pillars to raise awareness of tomorrow’s citizens.

Abstract

Pocos aspectos de las Ciencias de la Tierra y la vida, impartidos en Bachillerato, muestran las interrelaciones entre la Geología y la Biología. Además, los estudiantes españoles valoran, en general, mejor la Biología que la Geología, por la concurrencia de diversos factores como el desconocimiento de la Geología por su menor carga lectiva, los temarios excesivamente teóricos de esta, la escasa relación entre ambas ciencias o el mejor conocimiento que tienen de las salidas laborales de la Biología. En este trabajo revisamos el currículo estatal de Bachillerato para encontrar los bloques en los que es posible introducir una visión interdisciplinar relacionada con la Cristalografía y la Mineralogía, cuya enseñanza actual es poco integrada y motivadora como muestran diversos estudios. Proponemos diversos contenidos que se podrían abordar en las programaciones de aula relacionando los biominerales del cuerpo humano (huesos, dientes, etc.) y sus características mineralógicas y cristalográficas con su función anatómica y fisiológica. Los objetivos son, por una parte, utilizar la buena valoración de cuestiones sobre anatomía para introducir conceptos de Mineralogía menos conocidos y, por otra, motivar al alumnado por su estudio y valoración mostrando la importancia de estos en investigaciones y salidas laborales emergentes como la Geología Médica.

37. Messor barbarus ants as soil bioturbators: Implications for granulometry, mineralogical composition and fossil remains extraction in Somosaguas site (Madrid basin, Spain)

Abstract

Few studies have inquired about the relationship between myrmecological activity and the granulometry and mineralogy of sediments of a palaeontological site. The objectives of this article are to determine the sedimentological or mineralogical distinctions produced by ants of the species Messor barbarus when excavating their nests and extracting grains and vertebrate fossil remains from the Miocene palaeontological site of Somosaguas (Madrid, Spain), to evaluate the degree of taphonomic influence this myrmecological activity has on the fossil remains, and to decide whether or not it can be used as a tool for palaeontological prospection. Results show that Messor barbarus does not alter fossil remains when examined under a 10× binocular magnifying glass. Ants preferentially extract from the ant nest grains of medium sizes (0.25–2 mm) compared to the non-ant-modified soils, and also extract a higher quantity of feldspars. These significant granulometric and mineralogical modifications should be considered when carrying out compositional, sedimentological or stratigraphical studies, since these can become biased and alter geological interpretations as provenance or palaeoclimatic signal. Grain size selection could be due to Messor barbarus' physical capacities or the use of clay particles as cementing elements in nests. Mineralogical distinction may be related to feldspars' embayments and pits filled with finer material (mainly smectites), making transportation and pheromone impregnation easier. Results show that the ant mounds had increasing concentrations of fossil remains the nearer they were from the main excavation area, therefore the study of ant mounds in potentially fossiliferous zones can indeed be used as a new method of palaeontological prospection., Depto. de Geodinámica, Estratigrafía y Paleontología, Fac. de Ciencias Geológicas, TRUE, pub

Abstract

The mineralogical composition of the clay stratum (level 22) that contains the FLK Zinj-DS-PTK-AMK complex, the only example of pene-contemporaneous early Pleistocene sites occurring on the same palaeolandscape and simultaneously covered by the same ash fall tuff, shows significant intra-site and inter-site differences. Overall, level 22A is related to a more hydrologically closed system, with higher salinity and alkalinity than level 22B. Both levels show fresher water was entering the system from the DS area during deposition. Textural analysis of the studied samples shows great microporosity and abundant edge-to-edge and edge-to-face contacts between crystals. These results have major repercussions for the interpretation of the archaeological assemblages in the FLK Zinj-DS-PTK-AMK palaeolandscape. First, this implies that two distinct archaeological levels formed at different times with different environmental conditions in most of these localities. Second, textural analyses provide evidence that no important sedimentary compaction took place after the deposition of this layer. This affects interpretations of palaeolandscape geomorphology. Third, it shows that the sedimentary processes during all the clay sequence occurred in very low-energy conditions. This reinforces that no significant physical forces disturbed the original configurations of materials contained within these assemblages and reinforces their autochthony. Behavioural interpretations can, thus, be more solidly built upon the conception that those sites preserve most of their original in situ properties., Ministerio de Economía y Competitividad (MINECO), Ministerio de Cultura, Depto. de Mineralogía y Petrología, Fac. de Ciencias Geológicas, TRUE, pub

Behavioural interpretations can, thus, be more solidly built upon the conception that those sites preserve most of their original in situ properties.

Abstract

Democricetodon larteti es un roedor cricétido hallado en los yacimientos paleontológicos de Húmera (Aragoniense, Mioceno medio, Madrid). El estudio del desgaste en sus terceros molares (superiores e inferiores) ha permitido establecer un patrón de mortalidad que muestra un predominio de formas juveniles. Dicho patrón de mortalidad es similar al descrito en el cercano yacimiento de Somosaguas, en el que se considera que los individuos más jóvenes son los que más fácilmente morían debido a unas condiciones de vida muy adversas. El patrón de mortalidad de Húmera indicaría que los individuos de Democricetodon larteti podrían, como se ha descrito para Somosaguas, estar sometidos a una gran presión, por lo que raramente llegaban a alcanzar la edad adulta Democricetodon larteti is a cricetid rodent found in the paleontological deposits of Húmera (middle Aragonian, middle Miocene, Madrid). The study of wear in third molars (upper and lower) has allowed establishing a pattern of mortality that shows a predominance of juvenile forms. This mortality pattern is similar to that of the nearby Somosaguas site, where it is considered that the youngest individuals were most likely to die because there were very adverse living conditions. The mortality pattern of Húmera would indicate that the individuals of Democricetodon larteti could be subjected, similarly as described for Somosaguas, to a great enviromental pressure, so that they rarely reached adulthood

Abstract

Somosaguas-North (Madrid Basin, Spain) is a Middle Miocene mammalian fossil site embedded in debris-flow deposits. Very few debris-flow sites of Cenozoic age are known so an exhaustive taphonomic study of this site has been carried out in order to increase our knowledge about the formation of this type of assemblages. The deposits consist of matrix-supported, poorly-sorted coarse arkosic sandstones and fine conglomerates. A total of 6592 large-mammal remains have been retrieved, belonging to at least 10 different species. The most abundant taxa are the proboscidean Gomphotherium angustidens (11.92%) and the equid Anchitherium cursor (7.34%). Other taxa found at the site include the rhinocerotid Prosantorhinus douvillei, the suid Retroporcus complutensis, the moschid Micromeryx sp., the cervid Heteroprox sp., the bovid Tethytragus sp., the amphicyonid Amphicyon sp., the hemicyonid Hemicyon sp., and the felid Pseudaelurus sp. Although breakage is extremely common, well-preserved, complete to almost complete skeletal elements are also found. Bone remains are isolated, indicative of long exposure times (enabling decay and complete disarticulation) There are no associations of same-individual elements, suggesting that bones were profusely dispersed before or during debris-flow transport. The predominance of weathering stages 0 and 1 indicates that most of the bones were exposed a maximum of 3 years before burial. Based on the taphonomic evidence, we suggest that Somosaguas-North assemblage was formed by successive debris-flow transport and burial of different pre-existing thanatocoenoses, with varying taphonomic characteristics depending on their exposure time.
