Study suggests the T-Rex was about as smart as today's alligator

A study released last year suggested the Tyrannosaurus Rex were much more intelligent than what was assumed. VOA’s Rick Pantaleo spoke with Cristian Gutierrez, PhD, a research associate at the University of Alberta and author of a new study that disputes the previous findings, saying the brains of dinosaurs like T-Rex were more like reptiles and were about as smart as alligators.
