Dinosaur Tracks

Seeing a dinosaur skeleton in a museum may be thought-provoking, but seeing actually tracks in nature is downright exhilarating. Just South of Tuba City, Arizona, on a large tract of Navajo Nation land are the footprints of countless dinosaurs that roamed a marsh during the Jurassic Period about 200 million years ago. These are known as "trace fossils" since it is hard to say whether the prints are from one or many different, in this case plant-eating, Dilophosaurus wetherilli. What became of them, who knows? Tyrannosaurus Rex didn't arrive on the scene until 65 million BC, 135 million years later and the above herbivore had long been extinct. Tapir and Friends Animal Store encourages people to study the facts about dinosaurs and extinct animals and to become comfortable with the incredibly long history of life on the planet. See the wide selection of plastic dinosaurs and dinosaur skeleton puzzles for sale. They are so useful for science projects and as teaching devices.
