Cretaceous mammal tracks

Scientists have found rare mammal tracks from the dinosaur age at two sites in Colorado.

The tracks were found at a Golden, Colo., golf course known for fossil findings, and at another site often associated with dinosaur tracks 65 to 75 million years old.

Although fossilized dinosaur tracks are relatively common, mammal tracks from the same period are very rare, scientists said. One reason is mammals of the late Cretaceous era were about the size of rats and their footprints were small, inconspicuous and almost never register clearly.
