Bizarre New Dinosaur Shows Evolution to Plant Eating, Study Says

First noticed by a black market fossil dealer, a new species found in a Utah boneyard may be a missing link in dinosaurs’ trend toward vegetarianism.

The 125-million-year-old fossils, from the dinosaur Falcarius utahensis, were discovered in a graveyard of hundreds, if not thousands, of individuals. Though it may have eaten meat, Falcarius’s teeth and guts show the first signs of the species’s change toward a leafy, green diet, said James Kirkland, a paleontologist at the Utah Geological Survey in Salt Lake City.
