Homeschool Class: On the Trail of the World's Oldest Dinosaurs

Ages 5+

BadgerTalks presents Dr. Dave Lovelace from the UW Geology Team. For many decades the first dinosaurs were thought to be restricted to the southern hemisphere due to major climatic barriers. It was thought that there was al 10-15 million year lag between their first appearance and when they finally made it north of the equator. However, UWGM-led expeditions to the Popo Agie Formation of Wyoming have uncovered several new taxa that tell a different tale, one that overthrows the ‘southern hemisphere origins’ of dinosaurs and supports an early cosmopolitan distribution.
