Did you know the UW Geology Museum is home to fossils from the oldest known dinosaur in the northern hemisphere? The two bone fragments belong to a creature called Ahvaytum bahndooiveche that lived 230 million years ago and were discovered in Wyoming in 2013 by a UW-Madison team led by Dr. Dave Lovelace. 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 W. Dayton St. is free and open to the public.
