Research being published today in the science journal Nature details what paleontologists in Utah are calling the first dinosaur to go vegetarian.

The dinosaur, found in the mountains of eastern Utah, lived about 130 millions years ago. Scientists said an examination of its teeth showed it began to turn away from meat to plants.

The new species is the first to show the change, according to paleontologists, who aren't sure what prompted the dinosaur to change diets.
