The cast of a fossil piece, right, is part of the jaw bone of the lizard and is only about a third of the entire jaw. At left is a fossil of a smaller specimen. The lizard was researched by a team led by Jason Head, Earth & Atmospheric Sciences Assistant Professor at UNL. The lizard, which roamed the earth 40 million years ago, was the size of a German Shepherd. Photo by Craig Chandler / University Communications
