A rat-sized Purgatorius hides from a Bistahieversor dinosaur in a cretaceous forest.

A rat-sized Purgatorius hides amongst the undergrowth of a Cretaceous forest while a 30 foot long, 2,000 pound tyrannosaur forages for its next meal in what is today the western United States. Bistahieversor is a genus of tyrannosauroid dinosaur named after Bisti/De-Na-Zin Wilderness where it was found.. . Purgatorius is the genus for several species of small omnivorous mammals that are believed to be the among the earliest ancestors of modern-day chimps, rhesus monkeys, and humans. The extinction of the larger and more powerful dinosaurs may have been what led to world's domination by mammals today.. . While there is no direct evidence that Purgatorius and Bistahieversor ever shared the same wilderness, this image is yet illustrative of the predator-prey relationship that characterized dinosaurs and mammals for many millions of years.
