The presence of more than four different “plagiaulacidan” multituberculate taxa in the late Hauterivianeearly Barremian of the Galve area suggests a high biodiversity of these mammal faunas in the Early Cretaceous age of the Iberian Peninsula.

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 asCaririchnium isp. and Iguanodontipodidae indet.

  • Early Cretaceous) Wessex Formation of the Isle of Wight, Southern England
    A new albanerpetontid amphibian from the Barremian (Early Cretaceous) Wessex Formation of the Isle of Wight, southern England STEVEN C. SWEETMAN and JAMES D. GARDNER Sweetman, S.C. and Gardner, J.D. 2013. A new albanerpetontid amphibian from the Barremian (Early Cretaceous) Wes− sex Formation of the Isle of Wight, southern England. Acta Palaeontologica Polonica 58 (2): 295–324. A new albanerpetontid, Wesserpeton evansae gen. et sp. nov., from the Early Cretaceous (Barremian) Wessex Formation of the Isle of Wight, southern England, is described. Wesserpeton is established on the basis of a unique combination of primitive and derived characters relating to the frontals and jaws which render it distinct from currently recognized albanerpetontid genera: Albanerpeton (Late Cretaceous to Pliocene of Europe, Early Cretaceous to Paleocene of North America and Late Cretaceous of Asia); Celtedens (Late Jurassic to Early Cretaceous of Europe); and Anoualerpeton (Middle Jurassic of Europe and Early Cretaceous of North Africa). Although Wesserpeton exhibits considerable intraspecific variation in characters pertaining to the jaws and, to a lesser extent, frontals, the new taxon differs from Celtedens in the shape of the internasal process and gross morphology of the frontals in dorsal or ventral view. It differs from Anoualerpeton in the lack of pronounced heterodonty of dentary and maxillary teeth; and in the more medial loca− tion and direction of opening of the suprapalatal pit. The new taxon cannot be referred to Albanerpeton on the basis of the morphology of the frontals. Wesserpeton currently represents the youngest record of Albanerpetontidae in Britain. Key words: Lissamphibia, Albanerpetontidae, microvertebrates, Cretaceous, Britain. Steven C.

  • Constraints on the Timescale of Animal Evolutionary History
    Palaeontologia Electronica palaeo-electronica.org Constraints on the timescale of animal evolutionary history Michael J. Benton, Philip C.J. Donoghue, Robert J. Asher, Matt Friedman, Thomas J. Near, and Jakob Vinther ABSTRACT Dating the tree of life is a core endeavor in evolutionary biology. Rates of evolution are fundamental to nearly every evolutionary model and process. Rates need dates. There is much debate on the most appropriate and reasonable ways in which to date the tree of life, and recent work has highlighted some confusions and complexities that can be avoided. Whether phylogenetic trees are dated after they have been estab- lished, or as part of the process of tree finding, practitioners need to know which cali- brations to use. We emphasize the importance of identifying crown (not stem) fossils, levels of confidence in their attribution to the crown, current chronostratigraphic preci- sion, the primacy of the host geological formation and asymmetric confidence intervals. Here we present calibrations for 88 key nodes across the phylogeny of animals, rang- ing from the root of Metazoa to the last common ancestor of Homo sapiens. Close attention to detail is constantly required: for example, the classic bird-mammal date (base of crown Amniota) has often been given as 310-315 Ma; the 2014 international time scale indicates a minimum age of 318 Ma.

    Welcome! Welcome to the VI Symposium on Dinosaur Eggs and Babies, the return of this periodic gathering to the Iberian Peninsula, when it hatched eighteen years ago. From the slopes of the Pyrenees, we have followed the first steps of dinosaurs through France, Argentina, the United States and China. Today, we come back and see the coast where the first theropod embryos were discovered twenty years ago. Since the end of the last century, Paleoology, much like other branches of palaeontology, has evolved thanks to the advance of new methodologies and analytical tools, becoming a progressively more interdisciplinary area of knowledge. Dinosaur babies and embryos, rare findings back when these meetings started, seem to be everywhere now that we learn to look for them under the light of the microscope. New astonishing specimens allow us to understand how Mesozoic dinosaurs mate and reproduce. Oology, our parent discipline in the modern world, has made great advances in understanding the form and function of the egg, and its applications on poultry industry are countless. More than thirty contributions evidence that our field remains small but alive and healthy. We hope that you find in this Symposium an opportunity to share knowledge and open new lines of collaboration. And do not forget to enjoy your stay in Portugal.

Read Full License Page 1/23 Abstract Theropod behaviour and biodynamics are intriguing questions that paleontology has been trying to resolve for a long time. The lack of extant groups with similar bipedalism has made it hard to answer some of the questions on the matter, yet theoretical biomechanical models have shed some light on the question of how fast theropods could run and what kind of movement they showed. The study of dinosaur tracks can help answer some of these questions due to the very nature of tracks as a product of the interaction of these animals with the environment. Two trackways belonging to fast-running theropods from the Lower Cretaceous Enciso Group of Igea (La Rioja) are presented here and compared with other fast-running theropod trackways published to date.
