???Greetings,



This is a reminder about the technical session on echinoderm paleobiology scheduled for the 2014 annual Geological Society of America meeting in Vancouver, British Columbia  (10/19/14). This session will be titled, "Echinoderm Paleobiology: Phylogenetics, Morphology, and Evolutionary Ecology" and will address recent advances in understanding patterns of echinoderm evolution and paleontology. This session will be chaired by Jeffery R. Thompson (University of Southern California), Selina R. Cole (The Ohio State University), and me (David F. Wright, The Ohio State University).



Invited speakers include Colin D. Sumrall (The University of Tennessee), William I. Ausich (The Ohio State University), and James H. Nebelsick (Universität Tübingen).



Researchers interested in all aspects of echinoderm evolution are welcome to submit a proposal. All echinoderm groups and stratigraphic intervals will be treated with equal interest. A more detailed description of the technical session is provided below.



NOTE that the deadline for submitting a proposal is July 29, 2014.

Session details:

The phylum Echinodermata comprises a diverse and ecologically important member of modern and ancient ocean ecosystems. With recent advances in the understanding of echinoderm phylogeny, brought about through the NSF-funded Assembling the Echinoderm Tree of Life project and other similar research initiatives, it is now a more exciting time than ever for the field of echinoderm paleobiology. Due to their dense, well-sampled Phanerozoic fossil record, echinoderms are ideal organisms for testing broader evolutionary and ecological hypotheses in deep time. Advances in understanding homologies between and among echinoderm clades has informed phylogenetic studies and produced new interpretations of trait evolution within the echinoderm bauplan. This revised evolutionary framework provides a detailed historical context for investigating biologic and geologic processes underpinning macroevolutionary and paleoecological dynamics. The goal of the proposed session is to provide a setting for presenting the most up-to-date and novel research in echinoderm phylogenetics, morphologic evolution, and paleoecological interactions. This session will emphasize the utility of echinoderms in furthering our understanding of global change over geologic time, such as mass extinctions and long-term secular changes in the Earth-Life system. All aspects of echinoderm paleobiology are welcome including, but not limited to:  phylogenetics, macroevolution, diversity, paleoecology, taphonomy, systematics, functional morphological trends, and the use of geochemistry in understanding echinoderm evolution.



Cheers,



-Davey
