What a dinosaur handprint reveals
At left, dinosaur tracks with hand prints show bird-like inward-facing palms
at Johnson Farm, Utah.
At right, an artist's reconstruction shows the formation of the tracks by
the large meat-eating dinosaur Dilophosaurus some 198 million years ago.
The discovery from a 198-million-year-old crouching carnivore indicates that
even early dinosaurs had forelimbs similar to those of birds.
