The Sound of Little Dinosaur Feet

Paleontologists working just a couple hours' drive from my house, in Morrison, Colorado (west of Denver) report an exciting and unusual find: tracks of baby dinosaurs, in this case some species of Stegosaurus. The tracks are about the size of a U.S. half dollar and indicate the critters were somewhere around the size of human babies at that point. Morrison Natural History Museum director Matthew Mossbrucker says,"The tracks are so crisply preserved that I can imagine the sound of tiny feet splashing up water when the baby dinosaurs came to this ancient river to drink and cool down."
