Royal Tyrrell Museum Speaker Series - Dr. David G. DeMar, Jr.
The evolutionary history of tuatara and its extinct relatives including a new species from the Upper Jurassic of Wyoming, U.S.A.

Rhynchocephalia are a group of lizard-like reptiles that were species-rich and biogeographically widespread during the Mesozoic. Today, only the modern tuatara survives in New Zealand. For my presentation I will reveal new insights into the morphology and evolution of these reptiles on the basis of a nearly complete fossil skeleton of a new, small-bodied rhynchocephalian from Wyoming.
