Ammonites begin showing up in the fossil record from about 300 million years ago and went extinct with the dinosaurs. They were a very common animal that lived in oceans all over the world. We know a lot about ammonites including that they are the relatives of the still-living nautiloid. The fossils have been found ranging from very tiny to full-grown human size. The intricate patterns in the fossil are created from the interior structure of the shell. As it grows the animal creates a new, larger chamber to live in and seals up the previous chamber.
