UT research instrumental in determining extinction of the dinosaurs

It’s probably the very first “unsolved mystery” – what happened to the dinosaurs? Why aren’t they still with us? And it’s been an unsolved mystery for more than 60 million years. It may not be anymore, thanks to important work done by UT Austin. On Good Day Austin Saturday morning, Sean Gulick, a research professor at UT’s Jackson School of Geosciences joined Good Day’s Casey Claiborne and Chelsea Andrews to talk about how it’s clear now: an asteroid really did take out the dinosaurs.
