A Prehistoric 'Lizard King' Named for Morrison

Caption

Barbaturex morrisoni -- "Morrison's Bearded King" -- lived in an ecosystem with a diversity of both herbivorous and carnivorous mammals during a warm age in the earth's history 36 to 40 million years ago. It was larger than most of the mammals with which it lived, suggesting that competition with mammals did not restrict its evolution into a giant.
