View all City Cast Madison episodes

Earlier this month, The UW Geology Museum announced the discovery of the oldest known dinosaur in the northern hemisphere, dating back 230 million years. The two bone fragments, small enough to put in your pocket, were discovered in Wyoming in 2013 by Dr. Dave Lovelace and a field crew. The chicken-sized dinosaur is called Ahvaytum bahndooiveche. Host Bianca Martin chats with Lovelace about Ahvaytum, other Northern Hemisphere dinosaurs, and the collaboration with the Northern Arapaho Tipo and Eastern Shoshone Tipo Tribal Historic Preservation Offices.

The UW Geology Museum at 1215 West Dayton St. is free and open to the public.
