PhD Research Fellowship in Paleobiology/Paleontology in Oslo

PhD Research Fellowship in Paleobiology/Paleontology

A 4-year PhD position (SKO 1017) is available at the Natural History Museum (NHM), University of Oslo.

The Natural History Museum, University of Oslo, is the largest of its kind in Norway with approximately 150 employees engaged in research, teaching, curation and outreach in Botany, Mycology, Zoology, Paleontology and Geology.

Job description

The main objective of this PhD project is to investigate the underlying patterns and processes of the Ordovician Radiation, also known as the Great Ordovician Biodiversification Event (GOBE). The Ordovician (488.3 to 443.7 million years ago) was a period in the history of the biosphere that saw a very rapid diversification of many groups of fossilizable organisms. The temporal patterns of diversity changes seem to be in part unique across different groups of organisms and in different geographical regions, yet, there are also suggestions that globally operating agents may have contributed to this mother of all radiations. This controversy calls for both the reanalysis of existing data using better statistical tools as well as new collection of fossil and paleoenvironmental data aimed at answering specific questions, to boost existing knowledge.

This project will involve studying diversification dynamics in the deep past by combining data and insights from fresh field collections, museum collections, the literature and public databases. Depending on the past training and academic inclinations of the successful candidate, she/he may be involved in fieldwork in Ordovician outcrops, compiling existing data, and/or the development of statistical methodology for paleobiology. The successful candidate will join an actively growing Paleobiology and Macroevolution group at the University of Oslo and will be part of the scientific community at both the Natural History Museum and at the Department of Biosciences at the University of Oslo. The Natural History Museum in Oslo has a globally known, large collection of Ordovician fauna that will be crucial to the development of this project. Our research spans analytical paleontology, macroevolution, macroecology and the statistical tools in paleobiological research. This PhD posi! tion is in part funded by Norwegian Research Council grant to Lee Hsiang Liow, and in part by the Natural History Museum of Oslo. The successful candidate will also likely collaborate with Seth Finnegan (University of California, Berkeley), Melanie Hopkins (American Museum of Natural History), and Björn Kröger (University of Helsinki), as well as other colleagues at the Natural History Museum, Oslo and at the Department of Biosciences at the University of Oslo.

Nuevas evidencias de leopardos en el Pleistoceno superior de Valencia



El año pasado para estas fechas os comentamos la noticia de un hallazgo excepcional. El esqueleto de un leopardo fósil completo hallado en una cavidad valenciana (Avenc de Joan Guitón). Ahora tenemos el gusto de comunicaros que el trabajo científico sobre este esqueleto ha salido a la luz recientemente.

En dicho artículo se realiza un completo estudio del esqueleto poniendo de manifiesto que el ejemplar de Avenc Joan Guitón es uno de los más completos del mundo. Además en este trabajo se presentan nuevos restos de leopardo de varios yacimientos de la zona valenciana como son: Cova del Racó del Duc, Cova de les Malladetes, Cova Negra, Cova del Bolomor.

Por otro lado los autores han realizado una profunda revisión de la distribución del leopardo en el Pleistoceno. En ella se pone manifiesto lo abundantes que eran los leopardos en la Península Ibérica donde se ha constatado la presencia de este gran felino en más de ochenta yacimientos. Esto convierte a la Península Ibérica en el área con una mayor densidad de yacimientos con dicho taxón del mundo. Por otro lado en la Península se han constatado algunas de las citas más recientes para este taxón en Europa lo que la convierte en un área refugio para dicho taxón hasta su desaparición de Europa.

La elevada presencia de restos de leopardo en yacimientos arqueo-paleontológicos ha permitido a los autores estudiar las relaciones entre nuestros antepasados y este gran felino. Por tanto ha permitido describir los contextos de aparición y origen de los restos de leopardos, además se han valorado los procesos de interacción con los grupos humanos prehistóricos.

 El trabajo se ha publicado en la prestigiosa revista Quaternary Science Reviews y ha sido liderado por Alfred Sanchis del Museu de Prehistòria de València, en dicho trabajo han colaborado miembros de la Universitat de València, Club d'Espeleologia l'Avern d’Ontinyent, del Museu Arqueològic d'Ontinyent y el aragosaurero Víctor Sauqué.

Sobre la paleobiodiversidad de terópodos en el cretácico superior de los Pirineos


Los dientes aislados de terópodos son los fósiles más abundantes de estos dinosaurios en el Cretácico Superior de los Pirineos, siendo prácticamente inexistente fósiles del resto del esqueleto. A pesar de esto, los dientes son lo suficiente diagnósticos para identificar diferentes tipos de terópodos. De esta manera un equipo formado por investigadores de la Universidad de Alberta (Canadá), la Universidad del País Vasco y nuestro aragosaurero José Ignacio Canudo han demostrado que en los últimos millones del Cretácico vivieron, al menos, ocho especies diferentes de dinosaurios carnívoros en lo que hoy conocemos como los Pirineos.

El trabajo acaba de ser publicado por fin en la prestigiosa revista Acta Paleontologica Polonica. Ha estado casi dos años en prensa, pero ya se puede descargar la versión definitiva. En el trabajo se estudian dientes aislados de los yacimientos de Laño (Condado de Treviño), Arén (Huesca) y diversas localidades del entorno de Tremp (Lleida). Es material obtenido en diferentes campañas de prospección y excavación en la década de los 1990 y 2000. Estudiados en conjunto con métodos multivariantes ha permitido diferenciar, al menos, seis taxones diferentes. Uno de gran tamaño, el resto serían de mediano o pequeño. Estos seis habría que añadir dos más descritos por otros autores, una forma cercana a Richardoestesia y un ornitomimosaurio. De todos estos taxones no se conocen otros huesos. Sin duda es un reto encontrar buenos ejemplares de terópodos en el Cretácico superior del Pirineo en los próximos años.

Este estudio demuestra como una había una significativa paleobiodiversidad de terópodos al final del Cretácico, es decir unos millones de años antes del límite, o dicho de otra forma, un poco antes del impacto de gran meteorito responsable, al menos en parte, de su extinción. El intervalo estudiado es amplio, ya que recoge yacimientos del final del Campaniense hasta final del Maastrichtiense, por lo que no todos los taxones tuvieron que convivir a la vez. Es también reseñable que la mayoría dos terópodos se incluyan en coelurosaurios, es decir terópodos emparentados directamente con nuestras aves. Por tanto, estas formas emplumadas serían uno de los elementos más comunes en las planicies cercanas a la costa que formarían nuestros actuales Pirineos.


Os adjuntamos el resumen original:

The dinosaur record in the South Pyrenees Basin is diverse and rich. A total of 142 theropod teeth were studied for this paper, which constitutes one of the richest samples for these remains in Europe. Eight upper Campanian to upper
Maastrichtian outcrops from the Pyrenees produced six non-avian theropod taxa (Theropoda indet., Coelurosauria indet., ?Richardoestesia, ?Dromaeosauridae indet., ?Pyroraptor olympius, ?Paronychodon). These six taxa are added to two
previously described theropods (a Richardoestesia-like form and a possible ornithomimosaurid), indicating that there was considerable theropod diversity on the Iberian Peninsula during the Late Cretaceous.

Icnitas de hace 250 millones de años en el Moncayo

Una de las piezas del Museo de Ciencias Naturales de la Universidad de Zaragoza con más interés mediático y científico son dos lajas con icnitas del Triásico del Moncayo. Fue descrita inicialmente hace más de 100 años por el padre Navás y forma parte de la Colección Navás de los Padres Jesuitas. Varios miembros del equipo Aragosaurus-IUCA encabezados por Ignacio Martínez de la Universidad Nacional de Río Negro acaban de publicar un interesante artículo en la prestigiosa revista PeerJ donde estudian la placa con las icnitas, lo que les ha permitido encontrar nuevas icnitas y conocer la edad de la roca… y por ende de una de las formaciones que forma el Moncayo.

El padre Navás (1858-1938) fue un naturalista jesuita especialista en insectos, pero que también desarrollo interesantes trabajos en Paleontología. Uno de ellos fue el estudio de una enorme laja de más de 200 kgs recogida cerca del Santuario de la Virgen del Moncayo (Zaragoza) en 1895. En esta laja estudio unas icnitas que describió con el nombre de Chirosaurus ibericus. En 1906 la cambio de icnogénero y la asigno a Chirotherium ibericum. Esta icnogénero se conoce en el Triásico de muchas partes del mundo y lo produjo un tipo de reptiles, posiblemente arcosaurios, emparentados con los dinosaurios.

La nueva revisión apunta que la placa tiene icnitas que pueden identificarse como Chirotheriidae indet., Rhynchosauroides isp. y material sin poder ser identificado, además del holotipo de C. Ibericum. Tras un estudio morfométrico y biométrico la icnoespecie del Moncayo es similar a Chirotherium barthii. Esto tiene un gran interés ya que la icnoasociación C. barthii-Rhynchosauroides es típica del Olenekiense superior – Anisiense inferior en otras partes del mundo, es decir la antigüedad sería de unos 250 millones de años. Los resultados son muy interesantes ya que sitúan internacionalmente al holotipo de C. ibericus poniendo en valor el material depositado en el Museo y además abre una expectativa de trabajo en el área de Moncayo. Se trata de un amplio afloramiento del Triásico de un intervalo poco conocido a nivel nacional (tránsito Triásico inferior-medio) donde prácticamente no se han realizado trabajos de campo.
