David Polly is a vertebrate paleontologist at Indiana University-Bloomington and a Research Associate at the Field Museum in Chicago. He received degrees from the University of Texas—Austin (BA) and the University of California-Berkeley (Ph.D.), and was a postdoctoral fellow with the  Michigan Society and the Museum of Paleontology at the University of Michigan-Ann Arbor. For ten years he was at Queen Mary, University of London.  His current research is on trait-based community dynamics in vertebrates, especially the role of changing Cenozoic climates and environments to the composition of communities and the evolution of traits.  He is also interested in phylogenetics, phylogeography, and genetics of vertebrates.   David is committed to keeping scientific publication under academic control. He is currently an editor for Palaeontology and Palaeontologia Electronica, and has also worked actively to develop scientific internet publishing for the University of California Museum of Paleontology, the Society of Vertebrate Paleontology, and the Natural History Museum.

Dan Ksepka is a vertebrate paleontologist and evolutionary biologist at the National Evolutionary Synthesis Center. He received a BS in Geological Sciences from Rutgers University and a PhD in Earth and Environmental Sciences from Columbia University through the American Museum of Natural History joint fellowship program. His current research focuses on exploring patterns of congruence and disparity between fossil ages and molecular divergence dates. Dan is also interested in major evolutionary transitions in birds, especially the evolution of wing-propelled diving in penguins. He enjoys sharing science with all types of audiences and blogs at March of the Fossil Penguins (

James Parham is an evolutionary biologist at California State University-Fullerton, and the curator of paleontology at the John D. Cooper Archaeology and Paleontology Curation Center. He holds degrees from the University Rhode Island (Geology, BSc.) and the University of California-Berkeley (Integrative Biology, Ph.D). His postdoctoral training includes genomics (at the DOE Joint Genome Institute) and bioinformatics (at Biodiversity Synthesis Center). James has previously held positions as the curator of paleontology at the Alabama Museum of Natural History and as an assistant professor of biology at California State University-Bakersfield. His research interests include conservation genetics, systematic paleontology, and fossil calibrations. In all of these areas, his research utilizes, and demonstrates the important role of, museum specimens.
