We studied pictures of different fossils and drew and painted some of our own representations of Ammonites.
Marine animals, Ammonites lived during the periods of Earth history known as the Jurassic and Cretaceous, from about 201 million years ago, ending about 66 million years ago; the Ammonites became extinct at roughly the same time as the dinosaurs disappeared.
However, we know a lot about them because they are commonly found as fossils. Fossils are formed when the remains or traces of the animal became buried in sediment that later solidified into rock. Fossils of Ammonites can range in size from 22mm to over 2.5m in diameter.
