The Allosaurus Jimmadseni

Now Introducing…the Allosaurus Jimmadseni (1:05:16) Guest: Mark Loewen, Paleontologist, University of Utah More than 150 million years ago, the Allosaurus walked the earth. It’s one of the biggest predatory dinosaurs that existed, and also one of the most plentiful fossils out there, making it uniquely useful for study. All these specimens have helped paleontologists from the Utah Museum of Natural History identify a new species of allosaur, called the Allosaurus Jimmadseni.
