The Tyrannosaurus Rex is the indisputable king of the dinosaurs, but it wasn’t always that way. Lindsay Zanno -- director of paleontology and geology research at the North Carolina Museum of Natural Sciences, and assistant research professor in the department of biology at North Carolina State University -- helped discover a new dinosaur in North America. It is called Siats meekerorum, and it was one of the top three predators ever discovered in North America. In fact, it ruled over the early ancestors of the T-Rex.
Host Frank Stasio talks to Lindsay Zanno about her discovery.
