MEETING ANNOUNCEMENT

LONG NECKS, STRONG BITES,AND MONKEY LIZARDS:

Discovering the Weirdness of Early Mesozoic Reptiles

Dr. Adam Pritchard

Postdoctoral Fellow, Department of Geology and Geophysics

Yale University, New Haven, Connecticut.

Sunday, February, 19, 2017           2:00 P.M.            Room 319

American Museum of Natural History         New York City 

The Permo-Triassic Extinction 251 million years ago wiped out an estimated 90% of species living on Earth at that time. In the wake of that catastrophe, reptiles rapidly became the dominant back-boned animals across the planet, dominating land, sea, and air. Paleontologists have only just begun to understand this defining event in vertebrate evolution. Our understanding of this evolutionary radiation comes largely from records of large-bodied animals (total body length > 1 meter), although fragmentary and tantalizing evidence suggests that smaller reptiles were every bit as diverse. New paleontological field techniques, high-resolution CAT scanning, and three-dimensional modeling have begun to reveal such small reptiles for the first time.

Field excavations in the Triassic of New Mexico continue to produce new and bizarre small reptiles, from long-necked tanystropheids to chameleon-like drepanosaurs. However, the strangest of reptiles still linger unstudied in collections for decades. Scanning and modeling of skulls in the collections of the American Museum of Natural History and the Yale Peabody Museum reveal and entirely new group of lizard-like reptiles with powerful jaw muscles and a bird-like beak and expanded brain in a new species of drepanosaur. Our understanding of reptilian diversity at the dawn of the Mesozoic Era is only beginning.
