  • Descubren En Huesca Una Especie De Dinosaurios Desconocida En Europa
    TIERRA Descubren en Huesca una especie de dinosaurios desconocida en Europa La Universidad de Zaragoza ha descubierto en el municipio oscense de Arén fósiles de una nueva especie de dinosaurios hadrosáurido del subgrupo de los lambeosaurinos (con cresta), que se creía que nunca había existido en Europa, aunque sí en Asia y América. La revista geológica canadiense Canadian Journal of Earth Science acaba de publicar en su último número (diciembre de 2010) un trabajo con la descripción del nuevo dinosaurio hadrosáurido (“pico de pato”) español, llamado Blasisaurus canudoi. Unizar 9/12/2010 13:02 CEST Imagen de los fósiles hallados en Arén, correspondientes a Blasisaurus Canudoi.Foto: Unizar. Blasisaurus canudoi pertenecía al grupo de hadrosáuridos (picos de pato), llamados lambeosaurinos, que se caracterizaban por la presencia de estructuras alargadas o crestas en la cabeza (un ejemplo sería Parasaurolophus). Se trataba de un dinosaurio relativamente pequeño, que oscilaría entre los cinco y los siete metros de longitud, y con un peso que rondaría entre los 400 y 500 kilos. Además, poseía unas mandíbulas con cientos de dientes capaces de triturar las plantas más duras. La cresta craneal, formada por una serie de tubos por los que pasaba el aire, era utilizada para producir sonido y bramar en época TIERRA de celo. En todo el mundo existen unas 57 especies de hadrosáurios, y la hallada en Arén añade una más. El nombre de Blasisaurus ha sido dedicado al yacimiento Blasi (Arén), en el que se encontraron los restos y Canudoi, al paleontólogo aragonés José Ignacio Canudo, líder del Grupo Aragosaurus-IUCA (www.aragosaurus.com) de la Universidad de Zaragoza, por su contribución al estudio de los dinosaurios ibéricos.

Received: 8 January 2014 / Accepted: 18 December 2014 / Available online: 20 March 2015 Abstract In recent years a rich and diverse fauna of hadrosaurid dinosaurs has been described in the Upper Cretaceous of the Pyrenees. Recent fieldwork carried out in the upper Maastrichtian levels of the Tremp Formation, in the south-central Pyrenees (province of Huesca, north- eastern Spain), has allowed us to recover diminutive fossil bones referable to hadrosaurid dinosaurs. To date, small-sized specimens had not been reported in the area. The remains consist of small vertebrae and fragmentary long bones found in a relatively small area, so it is assumed that they probably belong to individuals of a single population. A morphological examination and a histological study reveal that they represent specimens of advanced ontogenetic stage and allow the identification of an undescribed taxon of small-bodied hadrosaurids.

Basal titanosauriforms were present in Japan during the Early Cretaceous before Aptian, and there is the possibility that the Brachiosauridae may have been included. Basal titanosauriforms with peg-like teeth were present during the “mid” Cretaceous, while the Titanosauria with peg-like teeth was present during the middle of Late Cretaceous. Recent excavations of Cretaceous sauropods in Asia showed that multiple lineages of sauropods lived throughout the Cretaceous in Asia. Japanese fossil records of sauropods are conformable with this hypothesis. Key words: Sauropod, Titanosauriforms, tooth, Cretaceous, Japan.

  • [I]Arenysaurus Ardevoli[I], First Paleoneuroanatomical Description of a European Hadrosaurid

View the peer-reviewed version (peerj.com/articles/802), which is the preferred citable publication unless you specifically need to cite this preprint. Cruzado-Caballero P, Fortuny J, Llacer S, Canudo J. 2015. Paleoneuroanatomy of the European lambeosaurine dinosaur Arenysaurus ardevoli. PeerJ 3:e802 https://doi.org/10.7717/peerj.802 Arenysaurus ardevoli, first paleoneuroanatomical description of a European hadrosaurid The neuroanatomy of hadrosaurid dinosaurs is well known from North America and Asia. In Europe only a few cranial remains have been recovered with the braincase. Arenysaurus is the first European endocast for which the paleoneuroanatomy has been studied. The resulting data have enabled us to draw ontogenetic, phylogenetic and functional inferences. Arenysaurus preserves the endocast and the inner ear. This cranial material was CT-scanned, and a 3D-model was generated. The endocast morphology supports a general pattern for hadrosaurids with some characters that distinguish to a subfamily PrePrints level, such as a brain cavity anteroposteriorly shorter or the angle of the major axis of the cerebral hemisphere to the horizontal in lambeosaurines. Both characters are present in the endocast of Arenysaurus. Moreover, osteological features indicate an adult ontogenetic stage while some paleoneuroanatomical features are indicative of a subadult ontogenetic stage and even a juvenile ontogenetic stage. Finally, a comparison with other hadrosaurids reveals that the low values for the angle of the dural peak may be an autapomorphy exclusive to the Parasaurolophus genus. It is hypothesized that the presence of puzzling characters that suggest different ontogenetic stages for this specimen, may reflect some degree of dwarfism in Arenysaurus.

  • Re-Description of the Sauropod Dinosaur Amanzia (“Ornithopsis
    Schwarz et al. Swiss J Geosci (2020) 113:2 https://doi.org/10.1186/s00015-020-00355-5 Swiss Journal of Geosciences ORIGINAL PAPER Open Access Re-description of the sauropod dinosaur Amanzia (“Ornithopsis/Cetiosauriscus”) greppini n. gen. and other vertebrate remains from the Kimmeridgian (Late Jurassic) Reuchenette Formation of Moutier, Switzerland Daniela Schwarz1* , Philip D. Mannion2 , Oliver Wings3 and Christian A. Meyer4 Abstract Dinosaur remains were discovered in the 1860’s in the Kimmeridgian (Late Jurassic) Reuchenette Formation of Moutier, northwestern Switzerland. In the 1920’s, these were identifed as a new species of sauropod, Ornithopsis greppini, before being reclassifed as a species of Cetiosauriscus (C. greppini), otherwise known from the type species (C. stewarti) from the late Middle Jurassic (Callovian) of the UK. The syntype of “C. greppini” consists of skeletal elements from all body regions, and at least four individuals of diferent sizes can be distinguished. Here we fully re-describe this material, and re-evaluate its taxonomy and systematic placement. The Moutier locality also yielded a theropod tooth, and fragmen- tary cranial and vertebral remains of a crocodylomorph, also re-described here. “C.” greppini is a small-sized (not more than 10 m long) non-neosauropod eusauropod. Cetiosauriscus stewarti and “C.” greppini difer from each other in: (1) size; (2) the neural spine morphology and diapophyseal laminae of the anterior caudal vertebrae; (3) the length-to-height proportion in the middle caudal vertebrae; (4) the presence or absence of ridges and crests on the middle caudal cen- tra; and (5) the shape and proportions of the coracoid, humerus, and femur.

  • Inferring Body Mass in Extinct Terrestrial Vertebrates and the Evolution of Body Size in a Model-Clade of Dinosaurs (Ornithopoda)
    Inferring Body Mass in Extinct Terrestrial Vertebrates and the Evolution of Body Size in a Model-Clade of Dinosaurs (Ornithopoda) by Nicolás Ernesto José Campione Ruben A thesis submitted in conformity with the requirements for the degree of Doctor of Philosophy Ecology and Evolutionary Biology University of Toronto © Copyright by Nicolás Ernesto José Campione Ruben 2013 Inferring body mass in extinct terrestrial vertebrates and the evolution of body size in a model-clade of dinosaurs (Ornithopoda) Nicolás E. J. Campione Ruben Doctor of Philosophy Ecology and Evolutionary Biology University of Toronto 2013 Abstract Organismal body size correlates with almost all aspects of ecology and physiology. As a result, the ability to infer body size in the fossil record offers an opportunity to interpret extinct species within a biological, rather than simply a systematic, context. Various methods have been proposed by which to estimate body mass (the standard measure of body size) that center on two main approaches: volumetric reconstructions and extant scaling. The latter are particularly contentious when applied to extinct terrestrial vertebrates, particularly stem-based taxa for which living relatives are difficult to constrain, such as non-avian dinosaurs and non-therapsid synapsids, resulting in the use of volumetric models that are highly influenced by researcher bias. However, criticisms of scaling models have not been tested within a comprehensive extant dataset. Based on limb measurements of 200 mammals and 47 reptiles, linear models were generated between limb measurements (length and circumference) and body mass to test the hypotheses that phylogenetic history, limb posture, and gait drive the relationship between stylopodial circumference and body mass as critics suggest.

Demandasaurus darwini, a new rebbachisaurid sauropod from the Early Cretaceous of the Iberian Peninsula. Acta Palaeontologica Polonica 56 (3): 535–552. A new medium−sized rebbachisaurid sauropod from the Castrillo la Reina Formation (Upper Barremian–Lower Aptian) in Burgos Province, Demandasaurus darwini gen. et sp. nov., is described. It is known from an incomplete but associated skeleton that includes cranial and post−cranial remains. Demandasaurus darwini gen. et sp. nov. presents 9 autapo− morphies in the teeth and vertebrae. Demandasaurus is the first diplodocoid sauropod described from the Cretaceous of the Iberian Peninsula. Its inclusion in the Rebbachisauridae is well supported by our phylogenetic hypothesis, which situ− ates it as a sister group of Nigersaurus from the Aptian of Niger, with which it shares various synapomorphies. The dis− covery of Demandasaurus provides further evidence of the sporadic use of the Apulian Route by dinosaurs during the Early Cretaceous for moving between the south of Europe (Laurasia) and the north of Africa (Gondwana).

The holotype of this Received 21 November 2018 species, which comes from the Sierra Barrosa Formation (upper Coniacian, Upper Cretaceous), consists of Received in revised form cranial, axial, and appendicular elements presenting an unique combination of plesiomorphic and 3 February 2019 apomorphic characters. The most notable characteristic observed in Kaijutitan is the presence of anterior Accepted in revised form 9 March 2019 cervical vertebrae with bifid neural spines, a condition that would have evolved several times among Available online 28 March 2019 sauropods. The phylogenetic analysis places Kaijutitan as a basal titanosaur, the sister taxon of Epachthosaurus þ Eutitanosauria. The new species supports the coexistence, in the Late Cretaceous Keywords: Sauropoda (Turonian-Santonian), of basal titanosaurs and eutitanosaurian sauropods, at least in Patagonia.

  • Evolution of the Caudal Vertebral Series in Macronarian Sauropod Dinosaurs: Morphofunctional and Phylogenetic Implications
    Evolution of the Caudal Vertebral Series in Macronarian Sauropod Dinosaurs: Morphofunctional and Phylogenetic Implications A Thesis Submitted to the Faculty of Drexel University By Lucio Manuel Ibiricu In partial fulfillment of the Requirements for the degree of Doctor of Philosophy October 2010 © Copyright 2010 Lucio Manuel Ibiricu. All Rights Reserved ii DEDICATION To the people who trusted me and my grandfather (Manolo) iii ACKNOWLEDGMENTS First of all, I want to thank my advisor, Dr. Lacovara, for several things: for admitting me in the program, for supporting me constantly, especially at the beginning of my experience in the United States and for exposing me to ―big‖ people in Paleontology. Ken gave me the opportunity to work and learn; I will always be grateful to him. I also thank Dr. Spotila, the head of my committee, for always supporting me and for helping in the organization, always very important during the PhD. I really appreciate it. In addition, I want to thank Dr. Dodson for accepting to be part of my committee. His presence is a privilege to me and it is an honor to say that he was part of my PhD committee. I would like to express my gratitude to Dr. Gallagher. He taught me the majority of my first courses at Drexel and I always learned a lot from him. Also, my first TA was under his supervision; therefore, I want to thank him for all the support he gave me both as student and as a TA. Likewise, I would like to thank Dr. Kilham, because her presence in my committee pushed me to learn more about ecology, which helped me integrate dinosaurs and their environment.
