There is a300 ft Wall in Bolivia which according to researchers has over 10,000 Dinosaur Footprints from approximately 10 Dinosaur species that inhabited our planet some 68 million years ago. link
I found this most interesting! Here's a link to google images if you'd like to see more. link
Those pictures are so cool and I would love to be able to go see it up close. It really gets my imagination going to wonder about all of the animals that made the different prints. My nephew used to be so into dinosaurs and this is something he would have been beyond thrilled to be able to see.
