Dinosaurs Arithmagons
Dinosaurs lived between 230 and 65 million years ago. Dinosaurs varied greatly in size, from the giants that were the size of a truck to the smaller dinosaurs some of which were the size of a small bird. Dinosaurs are now extinct and much of our knowledege is gained from dinosaur fossils.
