Nuevas icnitas de dinosaurios del Barremiense en Teruel


  Los aragosaureros acabamos de publicar un nuevo artículo sobre unas varios yacimientos icnitas de dinosaurios de la Formación Mirambel en el entorno de Ladruñán (Teruel). Es la primera vez que se describen icnitas en esta formación que permiten documentarlas en facies transicionales del Barremienses ibérico

La publicación forma parte de un volumen de la revista New Mexico Museum of Natural History and Science Bulletin. El volumen está dedicado el periodo Cretácico y lleva por título: "Cretaceous Period: Biotic Diversity and Biogeography". A lo largo del mismo pueden verse trabajos sobre temáticas muy variadas, desde trabajos más sedimentológicos a otros paleontológicos sobre grupos tan variados como ostrácodos, forminíferos, crustáceos, nanoplancton calcáreo etc.

Los vertebrados y dinosaurios ocupan una parte importante del volumen y hay varias publicaciones sobre material de la Península Ibérica. Por nuestra parte, hemos aportado nuestro granito de arena con una publicación sobre los yacimientos de icnitas de dinosaurios de la Fm. Mirambel, descubiertos en las campanas de prospección del año 2011.  De esta forma hemos descrito nuevas huellas de dinosaurios atribuidas a alguno de los principales grupos: terópodos, ornitópodos y saurópodos.

El modo de conservación es variado, las hay en forma de contramoldes, huellas verdaderas, subhuellas, algunas de las icnitas tienen una conservación excelente como la de terópodo de la fotografía. Es de destacar que los yacimientos con icnitas de la Fm. Mirambel están dominados por huellas de terópodos mientras que los yacimientos con restos osteológicos de la misma formación están dominados por ornitópodos, siendo los restos de terópodos muy escasos.

Os dejamos el resumen

Up to now, the ichnological vertebrate record from the Barremian Mirambel Formation (NE Spain) has remained completely unknown despite the fact that osteological findings have been reported in recent years. Here we provide an overview of 11 new dinosaur tracksites found during a fieldwork campaign in the year 2011. The majority of these tracksites (seven) preserve small- to medium-sized tridactyl tracks here assigned to indeterminate theropods. Only one footprint presents enough characters to classify it as Megalosauripus isp. Ornithopod tracks identified as Caririchnium isp. and Iguanodontipodidae indet. and sauropod tracks are recorded at two tracksites. The footprints are preserved in a variety of paleoenvironmental conditions and thus display different kinds of preservation (true tracks, shallow undertracks, natural casts and undertrack casts). The ichnological record from the Mirambel Formation seems to be theropod dominated. This is a clear discrepancy with the osteological record identified in this formation, which shows a predominance of ornithopod dinosaurs.

Postdoctoral Position: The interplay between Global Climate, Monsoons dynamics and the India-Asia collision

The Institute of Earth and Environmental sciences offers to join an interdisciplinary and international group of PhDs, postdocs and researchers focusing their expertise on solving one of the most fascinating question of Earth Sciences today: the interplay between global climate evolution, monsoonal dynamics and the India-Asia collision during the still enigmatic Paleogene greenhouse to icehouse transition.

This project is in the framework of the European Research Council (ERC) project MAGIC: “Monsoons in Asia caused Greenhouse to Icehouse Change?”

The primary goal will be to collect and identify fossil pollen assemblages from exceptional well-dated sedimentary archives from Central Asia and the Tibetan Plateau. The samples that you will work with are expected to contain a Laurasian flora ranging from humid to arid assemblages. Central to your research will be to record mountain uplift, sea retreat, aridification and monsoonal intensification as well as major global climate events such as the Eocene-Oligocene Transition (EOT) or the Paleocene Eocene Thermal Maximum (PETM).

The palynologic database produced will be used to reconstruct of past environments and geographies to ultimately calibrate geochemical, biomarker and sedimentologic proxies, to establish paleobiogeographies as well as constrain climate and vegetation models in collaboration with other scientists involved in the project.

Employment could start on October 1, 2016.

The position is for 40 hours of work per week (100 %). The salary is determined by the collective bargaining agreement for public employees in Germany (TV-L 13; Ost). This is a temporary position limited to a term of 24 months in accordance with Section 2 Para 1 of the Academic Fixed-Term Contract Law (WissZeitVG).

Los Tercios de Aragosaurus viajan al EAVP de Haarlem (Holanda)

Con motivo del XIV Congreso de la European Association of Vertebrate Palaeontologists (EAVP) realizado la semana pasada, varios investigadores del grupo Aragosaurus tuvieron la oportunidad de exponer sus últimos resultados científicos, siendo uno de los grupos de investigación con más asistentes al congreso. El lugar, Haarlem, una bonita localidad holandesa situada a 20 km al oeste de Ámsterdam y rodeada río Spaarne cercano a su desembocadura. El congreso tuvo lugar en el Teylers Museum, un bello edificio en pleno centro de la ciudad, dedicado a las artes y las ciencias, y que además es el museo más antiguo de los Países Bajos.

Como parte de la comitiva “maña” de la Universidad de Zaragoza, los investigadores Antonio Alonso, Pablo Navarro, Julia Galán, Raquel Moya, Carmen Núñez, Jara Parrilla, Ester Díaz y Eduardo Puértolas expusieron varios pósteres sobre temas tan dispares como arcosaurios (dinosaurios y cocodrilos) del Mesozoico del Pirineo oscense y Teruel, mamíferos (sirenios) del Eoceno de Huesca y micromamíferos (musarañas, aves y murciélagos) del Pleistoceno de Atapuerca (Burgos). Además, los aragosaureros Miguel Moreno de la Universidade Nova de Lisboa (Portugal) y Diego Castanera de la Ludwig-Maximilians-Universität de Múnich (Alemania) también estuvieron presentes con dos interesantes charlas sobre la acumulación de cáscaras de huevo de tortuga en un yacimiento de vertebrados en el Sobrarbe (Huesca) y sobre las icnitas de tetrápodos mesozoicos de la Cuenca de Cameros. 


En resumen, el congreso fue muy interesante ya que se trataron temas que iban desde la aparición de los primeros tetrápodos hasta la dispersión de los homínidos desde África. Además no faltó cierta polémica ya que parte de las charlas fueron enfocadas a los problemas y soluciones que afectan al patrimonio paleontológico, donde se pudieron escuchar los distintos puntos de vista entre paleontólogos, coleccionistas, vendedores de fósiles, así como las problemáticas asociadas con la legislación sobre el patrimonio de cada país.



Ahora solo queda esperar hasta el próximo congreso que será el año que viene por estas fechas en Múnich (Alemania), donde esperemos que la ciencia, la paleontología y las jarras de cerveza nos auguren otro interesante EAVP.

UN DIMINUTO DINOSAURIO DE BURGOS SOLUCIONA UN LINAJE FANTASMA

La Universidad de Zaragoza en colaboración con el Museo de Salas de los Infantes de Burgos ha descrito los restos de un nuevo y diminuto dinosaurio ornitópodo del Barremiense superior (125 millones de años) de Burgos en la prestigiosa revista PlosOne. Además han reconocido un nuevo grupo llamado Rhabdodontomorpha, de los cuales se conocían representantes en el Cretácico Superior, pero no en el Cretácico Inferior, intervalo temporal que se le consideraba como un linaje fantasma.

El nuevo estudio permite agrupar por primera vez a un tipo de dinosaurios con el nombre de Rhabdodontomorpha.  Se trata de un grupo de pequeños dinosaurios bípedos comedores de plantas bien representado en el final del Cretácico de diferentes yacimientos de Norteamérica y Europa, sin embargo carece de especies descritas en el Cretácico Inferior por lo que se ha considerado un ejemplo típico de Linaje fantasma en este intervalo temporal. Lo que en otros contextos se ha usado  como “eslabones perdidos”.  La historia de la evolutiva de los dinosaurios tiene numerosos huecos por rellenar, intervalos temporales que conocemos que un determinado grupo debía vivir, pero del que no se conoce registro fósil, ahora hay uno menos.


Los restos de un pequeño dinosaurio ornitópodo de Burgos encontrados hace más de 20 años y que estaban sin estudiar ha deparado la sorpresa de ser un representante primitivo de Rhabdodontomorpha. Dado que el material estudiado es fragmentario no se le ha asignado un nuevo nombre de especie, aunque claramente se trata de un nuevo taxón sin nombrar. Los huesos pertenecen a cinco ejemplares, al menos, procedentes yacimiento de Vegajete. Hay huesos de individuos adultos y juveniles o inmaduros, pero todos ellos son muy pequeños. El material es fragmentario y desarticulado, a pesar de lo cual hay representación de todos las partes del esqueleto, cráneo, vértebras, miembros, conservando casi completo uno de los pies. Diferentes investigadores habían predicho que tenía que haber estos pequeños dinosaurios bípedos en rocas de más de 100 millones de años (Cretácico Inferior), ya que sus descendientes se conocen en rocas de hace 70 millones de años (Cretácico Superior). El nuevo estudio confirma esta hipótesis, y por tanto han dejado de se un linaje fantasma. Un buen ejemplo de investigación científica aplicada a dinosaurios. 


La investigación forma parte de un convenio de colaboración entre la UZ y el Museo de Salas de Infantes. Ha sido liderada por los investigadores Paul Emile Dieudonné y José Ignacio Canudo del Grupo Aragosaurus-IUCA de la Universidad de Zaragoza, además han participado Fidel Torcida (Colectivo arqueológico y paleontológico de Salas), Thierry Tortosa (Réserve Naturelle Nationale Sainte-Victoire, Marsella, Francia), Ignacio Díaz Martínez (Universidad Nacional de Río Negro, Argentina).  Los fósiles se encuentran depositados en el Museo de Dinosaurios de Salas de los Infantes.
