One of the set of tracks, made about 150 million years ago, are the footprints of a small herd of four-legged sauropod dinosaurs .
The other set of tracks was made by a single, two-legged ornithopod dinosaur with a distinctive footprint of three huge toes.
What is mud is made from and how are footprints made?
