This Paleontologist made a surprising discovery after she dug up this Tyrannosaurus Rex & found this. Today, we take a look at what this Paleontologist found inside this Tyrannosaurus Rex.
66 million years ago, at the end of the Cretaceous period, the dinosaur's reign would come to an end. When the KT-extinction event occurred, about 70% of all species disappeared, and paleontologists who've studied this event have said that an unusually high number of large asteroid impacts struck the planet, setting off a chain reaction. Although researchers have done a great job at helping us understand dinosaurs, some mysteries still remain.
