Insights from 3D-imaging based analyses of carnivoramorphans and their relatives: Systematics, sinuses and sabertooths

Résumé

Techniques and methodologies that digitally capture three-dimensional information of fossils and extant specimens have become an integral and exciting part of current research in vertebrate paleontology. Over the past 25 years or so, advances in the computational capability of personal electronics and the more affordable availability of 3-D imaging instrumentation and related softwares (i.e., Computed Tomography facilities, 3-D laser surface scanners, 3-D photogrammetry and 3D-printing technologies) have permitted faster and more efficient 3-D acquisition of biological and paleontological data for visualization and analysis of new morphological information. We would like to highlight how exactly those impressive progresses can provide vertebrate paleontologists new tools to enhance the study of their respective taxonomic groups, but also to improve collection management, public exhibitions, and student training. This symposium will focus on developments of 3-D based analyses of placental carnivorous mammals (Carnivoramorpha) and their close relatives. Since their first appearance in the Paleocene continental deposits of North America, different carnivoramorphan clades emerged and experienced multiple diversification bursts through the Cenozoic. They now represent both an extremely rich source of modern biodiversity coupled with a tremendously diverse fossil record, and also are an essential guild component in terrestrial and aquatic ecosystems. A wide range of specialists from Europe and North America will provide examples of the latest insights on systematics and paleoecology, notably functional anatomy and sensorial capabilities, of various extant families of carnivorans as well as extinct hyaenodontids and basal carnivoramorphans based on cranial and postcranial digital data. In addition to highlight a particular 3-D imaging method for each poster, we will emphasize the related software programs and materials to use for education and research purposes. We strongly believe that his symposium will be relevant for the paleontologist community, pointing out the accessibility and efficiency of 3-D imaging data acquisition and analysis for the exploration of new anatomical information and the better understanding of macro-evolutionary process of evolution in diverse taxonomic groups. This annual SVP also provides a very appropriate host location for this symposium since the first scientific publications exploring CT-based 3D-imaging applications on paleontological specimens came of the largest NSF-funded scanning facility in the U.S. in Austin, Texas.
