Ancient mammal tracks found at dinosaur site

SALT LAKE CITY — Scientists at Dinosaur National Monument say they have found hundreds of tiny footprints left by mammals 190 million years ago.

Dan Chure, paleontologist at the monument, says he and paleontologist George Engelmann of the University of Nebraska at Omaha spotted the tracks earlier this month on a canyon wall.

Chure says the tracks are a rare find. They were left when the area was a vast Sahara-like desert, where towering sand dunes seldom preserved signs of life.
