Jason Head, Earth & Atmospheric Sciences Assistant Professor at UNL, holds a fossil and fossil cast from the jawbone of Barbaturex morrisoni, a giant ancient lizard named for the Doors musician Jim Morrison. The lizard, which roamed the earth 40 million years ago, was the size of a German Shepherd. On either side of Head are a mounted sailfin lizard that was closely related to Barbaturex and a skeleton of the modern plant-eating Iguana. May 15, 2013.
