Meet Siats (pronounced SEE-otts) Meekerorum, the first giant mega-predator to be discovered in North America — specifically in the Utah desert — in over 60 years. In this Untamed Science video, we hear from Dr. Lindsay Zanno, Director of the Paleontology & Geology Research Laboratory at the North Carolina Museum of Natural Sciences, who explains how this 30 foot long, 4-ton, carnivorous creature flourished in the tens of millions of years before T-Rex ruled.

Untamed Science has visited Dr. Zanno before: Paleontology 101, a must-watch for anyone who loves dinosaurs.
