Dr. Randall Irmis joins Cool Science Radio. Irmis is the Chief Curator and a Curator of Paleontology at the Natural History Museum of Utah, and he had a hand in discovering a new dinosaur right here in Utah in the Grand Staircase-Escalante National Monument. The announcement was made at a recent unveiling at the Natural History Museum of Utah. This dinosaur, the Akainacephalus johnsoni has a spiky bony armor covering the skull and snout and is about 76 million years old.
