New dinosaur footprints found F. A. Jones 03.23.01 Scientists have discovered the largest dinosaur footprints ever described. More than 100 footprints, some as large as four feet long and three feet wide, have been discovered in Northwestern China. The footprints are likely 100 million years old and come from at least four different dinosaur species. They were found was likely once the shore of a lake. Research suggests that the dinosaurs were left by a group of plant eating dinosaurs, perhaps being followed by a few meat eating ones.  A.
