Great Basin Chapter Online Meeting, February 8 at 7:00 PM MT with speaker Alex Ruebenstahl

Join the Great Basin Chapter of Utah Friends of Paleontology for an online meeting, February 8 at 7:00 PM MT.

Speaker: Alex Ruebenstahl, graduate student at Yale University.

Alex’s talk will be about the early evolution of coelurosaur dinosaurs and the importance of the historically significant Coelurus fragilis in understanding this. “Coelurosaurs are a clade of diverse theropod dinosaurs which includes Tyrannosaurus rex and Velociraptor mongoliensis but also birds and several lineages of bizarre herbivorous dinosaurs. The majority of species from this clade are known from the Cretaceous. We know that these groups originated in the Jurassic but are rare. As such, the early evolution of many coelurosaur groups is not well understood. One of the first described coelurosaurs, Coelurus fragilis, is from the Jurassic, but its relationships are poorly understood. New analyses of the syntype material, using CT scans, has revealed new information about the ecology, ontogeny (age) and evolutionary relationships of this taxa which has implications for the ecology of the Morisson formation and the early evolution of one major coelurosaur clade.”
