Resumen presentado en las XXXVII Jornadas de Paleontología y en V Congreso Ibérico de Paleontología., [ES] Los desiertos son ambientes estresantes para las formas de vida que para sobrevivir deben desarrollar diferentes estrategias. El llamado Sistema Desértico Ibérico se estableció en el norte y este de la península Ibérica desde el Albiense superior hasta el Cenomaniense inferior. Concretamente, los yacimientos del Albiense tardío de la Cuenca del Maestrazgo (Grupo Utrillas, Este de España) se conocen por contener ámbar con abundantes bioinclusiones que incluyen diversos artrópodos. El Grupo Utrillas se interpreta como un sistema desértico situado en las proximidades de la costa de Tethys, y engloba una sucesión sedimentaria formada por una alternancia de depósitos marinos someros y dunas eólicas. Los ecosistemas que se desarrollaron en esta zona fueron biodiversos, y estaban integrados por comunidades vegetales cuyos fósiles se asocian con indicadores sedimentológicos de aridez. La palinoflora identificada en las secciones con ámbar está dominada por granos de polen de gimnospermas transportados por el viento y/o esporas de helecho. Adicionalmente, el polen de angiospermas primitivas muestra una gran diversidad de formas pero nunca alcanza valores numéricos significativos. Por su parte, los quistes de dinoflagelados son raros y su presencia refleja incursiones marinas en ambientes cercanos a la costa. En general, las asociaciones palinológicas estudiadas indican la existencia de bosques de Cheirolepidiaceae y Cupressaceae adaptados a ambientes áridos, entornos costeros con Araucariaceae, y comunidades de interdunas y marismas con helechos y angiospermas. La presencia de asociaciones macroflorísticas poco diversas, caracterizadas por Frenelopsis, Eretmophyllum y algunas angiospermas, también señalan la existencia de marismas. La aparición de granos de polen de Afropollis, Dichastopollenites, Cretacaeiporites, así como los poliplicados producidos por Gnetales, revelan que estos ecosistemas desérticos presentaron influencias de los del norte de Gondwana. Por el contrario, las asociaciones macroflorísticas muestran una composición que las relacionas con comunidades laurasiáticas albienses y cenomanienses de Francia, y de la República Checa., Este estudio forma parte de los estudios realizados en el marco del Proyecto CRE (CGL2017-84419 – Evento cretácico de resina: Un bioevento global de producción en masa de resina en los albores de los ecosistemas terrestres modernos), financiado por la AEI/FEDER y la UE.

Simplifying, adapting and modifying physical education activities can be beneficial for student learning This article explains how to implement the mini-volleyball approach to maximize beginners' participation and learning opportunities in the sport of volleyball.

The purpose of this study was to examine physical education (PE) preservice teachers’ (PSTs) experiences applying the teaching personal and social responsibility model (TPSR) at the elementary level. Fuller’s (1969) theory of concern development served as a framework for this study. A purposive sample of nine PSTs (3 females, 6 males), majoring in PE teacher education, participated in the study. A focus group, observations, and diary reflections were used as data collection methods. Triangulation of the data and a member check process ensured the trustworthiness of the study. Results showed that PSTs were more prepared to teach the TPSR levels of helping others, effort, and autonomy at the elementary level. However, the level of respect was the most challenging level for PSTs to implement. Student misbehavior, planning, communication skills, and environmental factors emerged as practical instructional challenges in applying the TPSR. Finally, participants reported that the TPSR was vital and changed their beliefs regarding PE and contributes to developing values and life skills. Further research should address the concerns and gaps in the levels of respect and effort.

This article provides a practical example of interdisciplinary collaboration for applying the sport education model (SEM) to other subject matters, in this case math.

The Southwestern Iberian Domain (Southiberian Basin) corresponds to one of the five palaeogeographic domains into which the Iberian Basin was divided during the Late Jurassic-Early Cretaceous rifting stage. Although it was already known that this domain was clearly separated into two sub-basins, Cuenca and Valencia, the amelithostratigraphic scheme was assumed to be applicable to the whole domain. In the last decades, new data have been incorporated to the knowledge of the Serranía de Cuenca and the Alto Tajo region, showing that this area underwent a separated palaeogeographic evolution and developed a different stratigraphic record. Evidences of such independence are, among others, the development of a Late Jurassicearly Barremian unconformity with unique features in the Iberian Basin and herein described for the first time. Syn-rift sedimentation was controlled by an intricate extensional geometrical and kinematic pattern of multiple and small half-graben basins, and it is represented by just two unconformity-bounded units, late Barremian and Aptian in age respectively. This work reviews, clarifies, and simplifies old and confusing stratigraphic nomenclatures and proposes a specific lithostratigraphic scheme for the Alto Tajo-Serranía de Cuenca region. It includes the new upper Barremian Tragacete Formation and the redefinition of La Huérguina Formation in terms of lithofacies, lower boundary, age and environmental interpretation.

High-resolution single channel and multichannel seismic reflection profiles and multibeam bathymetric and backscatter data collected during several cruises over the period 1999 to 2007 have enabled characterising not only the seabed morphology but also the subsurface structural elements of the Yuma, Ginsburg, Jesús Baraza and Tasyo mud volcanoes (MVs) in the Gulf of Cádiz at 1,050–1,250 m water depth. These MVs vary strongly in morphology and size. The data reveal elongated cone-shaped edifices, rimmed depressions, and scarps interpreted as flank failures developed by collapse, faulting, compaction and gravitational processes. MV architecture is characterised by both extrusive and intrusive complexes, comprising stacked edifices (including seabed cones and up to four buried bicones) underlain by chaotic vertical zones and downward-tapering cones suggesting feeder systems. These intrusive structures represent the upper layer of the feeder system linking the fluid mud sources with the constructional edifices. The overall architecture is interpreted to be the result of successive events of mud extrusion and outbuilding alternating with periods of dormancy. Each mud extrusion phase is connected with the development of an edifice, represented by a seabed cone or a buried bicone. In all four MVs, the stacked edifices and the intrusive complexes penetrate Late Miocene–Quaternary units and are rooted in the Gulf of Cádiz wedge emplaced during the late Tortonian. Major phases of mud extrusion and outbuilding took place since the Late Pliocene, even though in the Yuma and Jesús Baraza MVs mud volcanism started in the Late Miocene shortly after the emplacement of the Gulf of Cádiz wedge. This study shows that fluid venting in the eastern sector of the Gulf of Cádiz promoted the outbuilding of large long-lived mud volcanoes active since the Late Miocene, and which have been reactivated repeatedly until recent times., Instituto Geológico y Minero de España, España, Instituto de Geociencias, Consejo Superior de Investigaciones Científicas, España, Instituto de Geociencias, Universidad Complutense de Madrid, España

[EN] A coastal marine siliciclastic unit has been studied from a palaeogeographic and structural-stratigraphic point of view. The unit was deposited during the Aptian in the extensional Las Parras sub-basin (Maestrazgo basin, E Spain), and it has been subdivided in four coarsening-upward sequences. A general description of each sequence is done but we focus in the third sequence (S3), which is built up of fi ne to coarse-grained sandstones, representing a vertical facies shift from storm dominated lower shoreface to upper shoreface environments. Both physical and genetic criteria have been used to correlate sequence S3. Top of sequence S3 is a minor erosive surface and is considered a reliable cronostratigraphic datum for correlation across the study area. Lateral facies changes of sequence S3 suggest the location of a siliciclastic discharge system toward the southeast of the study area. Drainage entry could be related to an intersection of basin bounding faults. Over the datum surface, coarsening upwards sequence S4 lacks its lower part in the south-easternmost area. An intra-S4 local discontinuity is defi ned and correlated toward the north-western area. The south-eastern area was located over a different subsiding block than the other sections and different subsidence histories for these blocks are interpreted on the basis of thickness trends and features of the intra-S4 discontinuity. Intra-S4 discontinuity marks the change from siliciclastic to carbonate dominated sedimentation, thus it could be representing a major break in the sedimentary dynamic. Spatial thickness trends of each sequence at the intra-block scale probably represent alternating episodes of homogeneous and heterogeneous subsidence that may be related to extensional dynamics., [ES] Durante el Aptiense, en la Subcuenca de Las Parras (NW Cuenca del Maestrazgo) se depositó una unidad siliciclástica en un contexto tectónico extensional. Esta unidad se ha dividido en cuatro secuencias granocrecientes, de las cuales se analiza en detalle la tercera (S3) ya que presenta un alto potencial de correlación lateral. El análisis sedimentológico de la secuencia S3 ha permitido interpretar una evolución vertical de shoreface inferior con procesos de tormenta, a shoreface superior; también ha permitido correlacionar esta secuencia entre dos sectores de la subcuenca que presentan un desarrollo litológico considerablemente diferente. El techo de la secuencia S3 es una superfi cie erosiva menor con valor cronoestratigráfi co y se ha utilizado como datum de correlación para el análisis de la unidad siliciclástica. Las variaciones laterales de facies de la secuencia S3 permiten interpretar la proximidad de un sistema de descarga siliciclástico hacia el sureste, y se propone una zona de intersección de fallas normales, próxima al sector suroriental de la zona estudiada, como un elemento paleoestructural favorable para la entrada de un sistema de drenaje en la cuenca. En el sector suroriental, por encima del datum de correlación, la secuencia S4 presenta un desarrollo muy reducido debido a la ausencia de su parte inferior; esto ha permitido interpretar la presencia de una discontinuidad local intra-S4. Esta discontinuidad local se correlaciona con otra reconocida en el sector noroccidental. Debido a las diferencias de espesor y al grado de desarrollo de la discontinuidad intra-S4 se deduce que la historia de subsidencia de diferentes bloques de la cuenca no es exactamente la misma. Esta discontinuidad intra-S4 podría tener interés regional ya que separa sedimentos dominantemente siliciclásticos de sedimentos carbonatados y podría indicar una modifi cación importante del sistema sedimentario. Para uno de los bloques estudiados, las variaciones espaciales de espesor para cada secuencia podrían representar un desarrollo de la subsidencia alternando periodos con subsidencia diferencial atenuada y periodos con subsidencia diferencial acentuada, que pueden estar relacionados con la dinámica extensional., Reviews by P. Monaco and P.A. Ruiz Ortiz improved the quality of this work.

[ES] El registro estratigráfico del Cretácico Inferior de la Cubeta de Aguilón está caracterizado por dos unidades litoestratigráficas: Fm. Villanueva de 1-Inerva y Fm. Aguilón. Estas unidades abarcan un intervalo temporal queincluye desde el Valanginiense y/o 1 lauteriviense al Barremiense basal (Soria et al., 1995). El análisis de discontinuidades dentro de la cuenca y la evolución sedimentaria de estas unidades ha permitido identificar a estos autores dos secuencias dc depósito. La Sil inferior comprende la Fm. Villanueva dc Huerva. Esta unidad evoluciona desde depósitos fluviales en su base hacia depósitos lacustres en su techo, dentro de un contexto retrogradante. Sin embargo, el tránsito desde las facies fluviales a las lacustres se produce mediante un sistema deltaico claramente progradante y cuyabase se correlaciona hacia el sur de la cuenca con un nivel calcáreo, con abundantes fósiles marinos (ostreidos, serpúlidos y foraminíferos bentónicos), interpretado como un nivel de tormenta. La S.D. superior comprende la Fm. Aguilón y se inicia prácticamente en toda la cuenca con facies aluviales y palustres. El resto de la secuencia está caracterizada por la expansión-retracción de un sistema lacustre carbonatado somero sometido a una fuerte dinámica de oleaje debido a tormentas. La formación y evolución de esta cuenca es consecuencia de una tectónica extensiva relacionad a conla etapa de rifting que tiene lugar durante el Cretácico Inferior en la Cuenca ibérica (Salas et al., 1991; Salas y Casas, 1993 474 A. 1?. Soria, A. Meléndez, M. 51. Meléndez y C. L. Líesa En esta cubeta, el espesor y distribución de facies de los sistema lacustres está controlado por dos sistemas de fallas. El sistema de fallas principal tiene una dirección WNW-ESE y el secundario es de dirección NNE-SSW., [EN] Two lithostratigraphie units are distinguished within tibe Lower Cretaeeous of the Aguilón subbasin: the Villanueva de Huerva and Aguilón Fms. These units span from the Valanginian-Hauterivian to ffie Eariy Barremian (Soria et al., 1995). The identification of regional unconformities and the sedimentary evolution of these units allows to distinguisli two depositional sequences. The lower depositional sequence corresponds to the Villanueva de Huerva Fm. and it displays a retrogradational pattern. Distal alluvial facies located at ita base grade up into a deltaic progradational system. Evidences for marine influence on the lower part of these facies are iocally found to the south of the subbasin, where an skeletal tempestite level (with serpulids, equinoderms, benthic foraminifera asid ostreids) is recognized. The upper part of the sequence consists of lacustrine carbonates. The upper depositional sequence comprises the Aguilón Fm. It displays alluvial and palustrine systems at ita base. These systems grade upward into a well developed shallow lacustrine system, represented by cross-bedded bioclastie grainstones and packstones, generated by storm-induced waves. The formation and evolution of the Aguilón subbasin is controlled by extensional tectonies related to tibe Early Cretaceous rifting in the iberian Basin (Salas et al., 1991; Salas and Casas, 1993). Two fault systems controlling thickness and facies distribution are identified in tSe Aguilón subbasin. The main fault system strikes WNW-ESE direction, asid tbe secondary fault system shows a .NNE-SSW orientation., Las autores de este trabajo quieren agradecer a Angel Cortés y al Dr. Antonio Casas la revisión y discusión del modelo tectónico y las ideas sugeridas a este respecto.

Trabajo presentado en el II International Symposium on Lithographic Limestones celebrado en Cuenca.-- Field trip guide book. The taphonomic anal ysis of the Las Hoyas site is still at an early stage. This analysis is necessary since it is considered a prerequisite for paleoecological reconstructions (Shipman, 1981). Besides, taphonomic analysis has its own aims; in this case they could be summarized as the establishment of the temporal succession of processes which led to the formation of the site.

Trabajo presentado en el II International Symposium on Lithographic Limestones celebrado en Cuenca.-- Field trip guide book., The biostratigraphic attribution of a fossil Lagerstätten such as Las hoyas is not simple in spite of the rich flora and fauna supplied by the paleontological site.

[ES] La cubeta de Las Hoyas (Serranía de Cuenca, Cordillera Ibérica) sufrió un relleno sedimentario complejo durante el Cretácico inferior. En un contexto de rift intracontinental, la cubeta de Las Hoyas se encontraba localizada sobre un bloque subsidente controlado por directrices tectónicas ONO-ESE y NO-SE. La variación a lo largo del tiempo del equilibrio entre la tasa de sedimentación y la tectónica sinsedimentaria activa, en interacción con una serie de factores intra y extracuencales (producción de carbonatos, llegada de aportes siliciclásticos, clima...) determinó una historia sedimentaria en tres episodios en los que la paleogeografía de esta cubeta estuvo dominada por diferentes arnbientes. En un primer Episodio se instaló una llanura aluvial distal. Un segundo Episodio está definido por la instalación en todo el área de un ambiente lacustre abierto. El tercer y último Episodio está representado por un ambiente de llanura aluvial distal con áreas lacustres marginales dominantes., [EN] Las Hoyas sub-basin (Serranía de Cuenca, Iberian Ranges) had a very complex sedimentary infilling during the Lower Cretaceous. This basin was settled on a subsident block, in a intracontinental rift context. This block was controlled by WNW-ESE and NW-SEtectonic lineations. lts sedimentary history was developped in three stages and was outlined by the interaction and the equilibrium among severa! factors: sedimentation rate, diferential subsidence, carbonate production, siliciclastic supply, climate... During the three stages the paleogeography was dominated by differents environments. During the first one a distal alluvial plain was installed in the area. A lacustrine environment was developped during the second stage. The third síage is represented by the installation of a distal alluvial plain dominated by marginal lacustrine areas.
