Ammonites • Fossils came from Germany • Date back the Mesozoic Era, about 150 million years ago. • They are cephalopod mollusks, related to octopuses, squid, and cuttlefish • Their bodies occupied the largest section of their shell.
Ammonites • The smaller sections were filled with a gas that helped them maintain buoyancy in the water. • They lived in the open ocean as predators, using their tentacles and rasping beaks to feed on small fish and crustaceans (shrimp, etc.) • They were probably preyed upon by marine reptiles, sharks, and other larger fish.
