  • Theropod Composition of Early Late Cretaceous Faunas from Central
    CORE Metadata, citation and similar papers at core.ac.uk Provided by Repository of the Academy's Library 1 Feeding related characters in basal pterosaurs: implications for jaw mechanism, dental function and diet RH: Feeding related characters in pterosaurs Attila Ősi A comparative study of various feeding related features in basal pterosaurs reveals a significant change in feeding strategies during the early evolutionary history of the group. These features are related to the skull architecture (e.g. quadrate morphology and orientation, jaw joint), dentition (e.g. crown morphology, wear patterns), reconstructed adductor musculature, and postcranium. The most basal pterosaurs (Preondactylus, dimorphodontids and anurognathids) were small bodied animals with a wing span no greater than 1.5 m, a relatively short, lightly constructed skull, straight mandibles with a large gape, sharply pointed teeth and well developed external adductors. The absence of extended tooth wear excludes complex oral food processing and indicates that jaw closure was simply orthal. Features of these basalmost forms indicate a predominantly insectivorous diet. Among stratigraphically older but more derived forms (Eudimorphodon, Carniadactylus, Caviramus) complex, multicusped teeth allowed the consumption of a wider variety of prey via a more effective form of food processing. This is supported by heavy dental wear in all forms with multicusped teeth. Typical piscivorous forms occurred no earlier than the Early Jurassic, and are characterized by widely spaced, enlarged procumbent teeth forming a fish grab and an anteriorly inclined quadrate that permitted only a relatively small gape. In addition, the skull became more elongate and body size 2 increased. Besides the dominance of piscivory, dental morphology and the scarcity of tooth wear reflect accidental dental occlusion that could have been caused by the capturing or seasonal consumption of harder food items.

Here we provide a detailed comparison of the anatomy of Ambiortus relative to other known Early Cretaceous ornithuromorphs from the Chinese Jehol Group and Xiagou Formation. We include new information on Ambiortus from a previously undescribed slab preserving part of the sternum. Ambiortus is superficially similar to Gansus yumenensis from the Aptian Xiagou Forma tion but shares more morphological features with Yixianornis grabaui (Ornithuromorpha: Songlingorni thidae) from the Jiufotang Formation of the Jehol Group. In general, the mosaic pattern of character distri bution among early ornithuromorph taxa does not reveal obvious relationships between taxa. Ambiortus was placed in a large phylogenetic analysis of Mesozoic birds, which confirms morphological observations and places Ambiortus in a polytomy with Yixianornis and Gansus.

  • A Reassessment of the Phylogenetic Position of Cretaceous Sauropod Dinosaurs from Queensland, Australia
    Asociación Paleontológica Argentina. Publicación Especial 7 ISSN 0328-347X VII International Symposium on Mesozoic Terrestrial Ecosystems: 139-144.Buenos Aires, 30-6-2001 A ReasSessmenT of the phylogenetic position of CretaceoUS SaUROPOd dinosaURS from Queensland, Australia Ralph E. MOLNAR1 Abstract. The Cretaceous sauropod material from Queensland, Australia, has been regarded as pertaining to a persistently primitive sauropod lineage (e.g., Coombs and Molnar). The specimens derive from the Toolebuc and Allaru (Albian marine) and Winton (Cenomanian continental) Formations. Recent phyloge- netic analyses carried out by workers in Argentina, the USA and England permit a reassessment of this fragmentary material. As far as can be ascertained from the material, there is no indication from the char- acter states that more than a single taxon is represented. Character states diagnostic of the Titanosauriforrnes, the Titanosauria, the Somphospondyli and the Titanosauridae are present. Thus the Queensland material does not pertain to cetiosaurids but belongs to titanosaurs, extending their range in- to Australia Key words. Sauropods. Austrosaurus. Titanosaurs. Cretaceous.

Universidad de Zaragoza. 50009 Zaragoza. [email protected] 2 Paleoymás, S. L. L. Nuestra Señora del Salz, 4, local, 50017 Zaragoza. [email protected] RESUMEN La mayoría de los restos fósiles de dinosaurios terópodos de España son dientes aislados y escasos restos postcraneales. La única excepción es el ornitomimosaurio Pelecanimimus polyodon, del Barremiense de Las Hoyas (Cuenca). Hay registro de terópodos en el Jurásico superior (Oxfordiense superior-Tithónico inferior), en el tránsito Jurásico-Cretácico (Tithónico superior- Berriasiense inferior) y en todos los pisos del Cretácico inferior, con excepción del Valanginiense. En el Cretácico superior únicamente hay restos en el Campaniense y Maastrichtiense. La mayor parte de las determinaciones son demasiado generales, lo que impide conocer algunas de las familias que posiblemente estén representadas. Se han reconocido: Neoceratosauria, Baryonychidae, Ornithomimosauria, Dromaeosauridae, además de terópodos indeterminados, y celurosaurios indeterminados (dientes pequeños sin dentículos). La mayoría de los restos son de Maniraptoriformes, siendo especialmente abundantes los dromeosáuridos. Las únicas excepciones son por el momento, el posible Ceratosauria del Jurásico superior de Asturias, los barionícidos del Hauteriviense-Barremiense de Burgos, Teruel y La Rioja, el posible carcharodontosáurido del Aptiense inferior de Morella y el posible abelisáurido del Campaniense de Laño. Además hay algunos terópodos incertae sedis, como los "paronicodóntidos" (entre los que se incluye Euronychodon), y Richardoestesia.

  • Brains and Intelligence
    BRAINS AND INTELLIGENCE The EQ or Encephalization Quotient is a simple way of measuring an animal's intelligence. EQ is the ratio of the brain weight of the animal to the brain weight of a "typical" animal of the same body weight. Assuming that smarter animals have larger brains to body ratios than less intelligent ones, this helps determine the relative intelligence of extinct animals. In general, warm-blooded animals (like mammals) have a higher EQ than cold-blooded ones (like reptiles and fish). Birds and mammals have brains that are about 10 times bigger than those of bony fish, amphibians, and reptiles of the same body size. The Least Intelligent Dinosaurs: The primitive dinosaurs belonging to the group sauropodomorpha (which included Massospondylus, Riojasaurus, and others) were among the least intelligent of the dinosaurs, with an EQ of about 0.05 (Hopson, 1980). Smartest Dinosaurs: The Troodontids (like Troödon) were probably the smartest dinosaurs, followed by the dromaeosaurid dinosaurs (the "raptors," which included Dromeosaurus, Velociraptor, Deinonychus, and others) had the highest EQ among the dinosaurs, about 5.8 (Hopson, 1980). The Encephalization Quotient was developed by the psychologist Harry J. Jerison in the 1970's. J. A. Hopson (a paleontologist from the University of Chicago) did further development of the EQ concept using brain casts of many dinosaurs. Hopson found that theropods (especially Troodontids) had higher EQ's than plant-eating dinosaurs. The lowest EQ's belonged to sauropods, ankylosaurs, and stegosaurids. A SECOND BRAIN? It used to be thought that the large sauropods (like Brachiosaurus and Apatosaurus) and the ornithischian Stegosaurus had a second brain.

Introduction Avian paleontology has long been a poor stepsister to its mammalian counterpart, a fact that may be attributed in some measure to an insufRcien- cy of qualified workers and to the absence in birds of heterodont teeth, on which the greater proportion of the fossil record of mammals is founded.

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.
