The tiny skull belonged to a young Heterodontosaurus. Its tooth structure — sharp canine teeth for biting and tearing and flat grinding teeth —suggest the tiny creature was evolving from a meat eater to a plant eater, the scientists said. "This juvenile skull indicates that these dinosaurs were still in the midst of that transition," said Laura Porro, a post-doctoral student at the University of Chicago, who described the skull in the Journal of Vertebrate Paleontology.
