PSW: The ‘Chicken from Hell’

The Paleontological Society of Washington

Wednesday, January 21, 7:00 pm, in the Cooper room (E-207A), National Museum of Natural History, Constitutional Ave. entrance

The ‘Chicken from Hell’ – an unusual new theropod dinosaur from the Upper Cretaceous of North America

Dr. Hans-Dieter Sues, Curator of Vertebrate Paleontology, NMNH

Oviraptorosauria is a clade of maniraptoran theropod dinosaurs with peculiar craniomandibular specializations. Most discoveries of oviraptorosaurs have been made in Asia, principally Mongolia and China, and as a result, the balance of our knowledge of the group is derived from fossils found on that continent. Anzu wyelei, a new, large-bodied (total length ~3.5 m) oviraptorosaurian taxon based primarily on three well-preserved partial skeletons from the late Maastrichtian of North and South Dakota, will be discussed. The new taxon offers the first comprehensive picture of the skeletal structure of Caenagnathidae and sheds light on long-standing controversies regarding the taxonomy and interrelationships of North American oviraptorosaurs. Furthermore, its analysis confirms caenagnathid monophyly and provides additional insight into the paleobiology of this enigmatic clade.

(Non-Smithsonian visitors will be escorted to the Cooper Room at 6:30 and 6:55 p.m.) Society members will host the speaker for dinner at the Elephant & Castle (1201 Pennsylvania Ave.) shortly after 5:00 prior to the meeting. Members may meet inside the Constitutional Ave. entrance of the NMNH at 5:00 and walk to the restaurant as a group.
