  • Theropod Composition of Early Late Cretaceous Faunas from Central

    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.

This includes the Wukongopteridae, a clade of non-pterodactyloids, where the presence or absence of such head structures, allied with variation in the pelvic canal, have been regarded as evidence for sexual dimorphism. Here we discuss the cranial crest variation within wukongopterids and briefly report on a new specimen (IVPP V 17957). We also show that there is no significant variation in the anatomy of the pelvis of crested and crestless specimens. We further revisit the discussion regarding the function of cranial structures in pterosaurs and argue that they cannot be dismissed a priori as a valuable tool for species recognition.

    EDITORS’CHOICE EDITED BY GILBERT CHIN AND JAKE YESTON B I O M E C H A N I C S No Skimming Allowed Pterosaurs were flying reptiles and the first air-borne vertebrates; they dominated the skies from the late Triassic to the end of the Cretaceous, during the epoch of their relatives, the dinosaurs. On the basis of similarities in jaw structure, it has been suggested that several pterosaurs, including Thalassodromeus and the giant Quetzalcoatlus (with a wingspan of up to 15 m), could have fed by skimming in a manner akin to that of extant ternlike shorebirds (Rynchops spp.) Skimmers fly low over calm shallow water with the tip of their lower beak dipping beneath the water surface. Humphries et al. have used full-sized mod- on August 31, 2007 els of mandibles from Thalassodromeus and the modern skimmer R. niger to demonstrate that the pterosaur bill would have generated an order of magnitude more drag in traveling through the water. Modeling indicated that the energetic cost to a shorebird of flying with its beak in the water is almost prohibitive (~20% of the total cost of flight), and the authors sug- gest this levy might explain the rarity of the skimming life-style. The substantially greater cost for a pterosaur larger than 2 kg appears to exclude outright skimming as a possible means for procuring food. Furthermore, many of the morpho- logical specializations to the head and neck seen in Rynchops are not found in pterosaurs of any size, including the ability to regenerate broken or abraded bill tips and the presence of a reinforced lower jaw.

    National Science Review REVIEW 1: 543–559, 2014 doi: 10.1093/nsr/nwu055 Advance access publication 5 September 2014 GEOSCIENCES Special Topic: Paleontology in China The Jehol Biota, an Early Cretaceous terrestrial Lagerstatte:¨ new discoveries and implications Zhonghe Zhou ABSTRACT The study of the Early Cretaceous terrestrial Jehol Biota, which provides a rare window for reconstruction of a Lower Cretaceous terrestrial ecosystem, is reviewed with a focus on some of the latest progress. A newly proposed definition of the biota based on paleoecology and taphonomy is accepted. Although theJehol fossils are mainly preserved in two types of sedimentary rocks, there are various types of preservation with a complex mechanism that remains to be understood. New discoveries of significant taxa from the Jehol Biota, with an updated introduction of its diversity, confirm that the Jehol Biota represents one of themost diversified biotas of the Mesozoic. The evolutionary significance of major biological groups (e.g. dinosaurs, birds, mammals, pterosaurs, insects, and plants) is discussed mainly in the light of recent discoveries, and some of the most remarkable aspects of the biota are highlighted. The global and local geological, paleogeographic, and paleoenvironmental background of the Jehol Biota have contributed to the unique composition, evolution, and preservation of the biota, demonstrating widespread faunal exchanges between Asia and other continents caused by the presence of the Eurasia–North American continental mass and its link to South America, and confirming northeastern China as the origin and diversification center fora variety of Cretaceous biological groups. Although some progress has been made on the reconstruction of the paleotemperature at the time of the Jehol Biota, much more work is needed to confirm a possible link between the remarkable diversity of the biota and the cold intervals during the Early Cretaceous.
  • An Unusual New Genus of Istiodactylid Pterosaur from China Based on a Near Complete Specimen

    An Unusual New Genus of Istiodactylid Pterosaur from China Based on a Near Complete Specimen

    Palaeontologia Electronica palaeo-electronica.org An unusual new genus of istiodactylid pterosaur from China based on a near complete specimen David W. E. Hone, Adam J. Fitch, Feimin Ma, and Xing Xu ABSTRACT A new genus and species of istiodactylid pterosaur, Luchibang xingzhe gen. et sp. nov., from the Lower Cretaceous Yixian Formation of China is erected based on a near complete specimen lacking only the posterior of the skull and the tail. The holotype individual is skeletally immature and already bigger than most istiodactylids suggesting a large wingspan at adult. This is the most complete istiodactylid specimen known to date and provides new information on the anatomy of this group and their putative ecology. The animal is unusual in having postcranial robust and elongate hindlimbs, which marks it as different to other istiodactylids and other pteranodontoids. David W. E. Hone.

    Is Our Understanding of Santana Group Pterosaur Diversity Biased by Poor Biological and Stratigraphic Control?

    Anhanguera taxonomy revisited: is our understanding of Santana Group pterosaur diversity biased by poor biological and stratigraphic control? Felipe L. Pinheiro1 and Taissa Rodrigues2 1 Laboratório de Paleobiologia, Universidade Federal do Pampa, São Gabriel, RS, Brazil 2 Departamento de Ciências Biológicas, Universidade Federal do Espírito Santo, Vitória, ES, Brazil ABSTRACT Background. Anhanguerids comprise an important clade of pterosaurs, mostly known from dozens of three-dimensionally preserved specimens recovered from the Lower Cretaceous Romualdo Formation (northeastern Brazil). They are remarkably diverse in this sedimentary unit, with eight named species, six of them belonging to the genus Anhanguera. However, such diversity is likely overestimated, as these species have been historically diagnosed based on subtle differences, mainly based on the shape and position of the cranial crest. In spite of that, recently discovered pterosaur taxa represented by large numbers of individuals, including juveniles and adults, as well as presumed males and females, have crests of sizes and shapes that are either ontogenetically variable or sexually dimorphic. Methods. We describe in detail the skull of one of the most complete specimens referred to Anhanguera, AMNH 22555, and use it as a case study to review the diversity of anhanguerids from the Romualdo Formation. In order to accomplish that, a geometric morphometric analysis was performed to assess size-dependent characters with respect to the premaxillary crest in the 12 most complete skulls bearing crests that are referred in, or related to, this clade, almost all of them analyzed first hand. Results. Geometric morphometric regression of shape on centroid size was highly Submitted 4 January 2017 statistically significant (p D 0:0091) and showed that allometry accounts for 25.7% Accepted 8 April 2017 Published 4 May 2017 of total shape variation between skulls of different centroid sizes.

Palaeontology in the virtual era BOOK OF ABSTRACTS 6 4 PRESENTATION The 1st Palaeontological Virtual Congress (1st PVC) is just the natural consequence of the evolution of our surrounding world, with the emergence of new technologies that allow a wide range of communication possibilities. Within this context, the 1st PVC represents the frst attempt in palaeontology to take advantage of these new possibilites being the frst international palaeontology congress developed in a virtual environment. This online congress is pioneer in palaeontology, offering an exclusively virtual-developed environment to researchers all around the globe. The simplicity of this new format, giving international projection to the palaeontological research carried out by groups with limited economic resources (expensive registration fees, travel, accomodation and maintenance expenses), is one of our main achievements. This new format combines the benefts of traditional meetings (i.e., providing a forum for discussion, including guest lectures, feld trips or the production of an abstract book) with the advantages of the online platforms, which allow to reach a high number of researchers along the world, promoting the participation of palaeontologists from developing countries.
