Ammonites were early mollusks. These marine animals had no vertebrae and were protected by a hard shell (usually coiled) made from calcium. Fast-moving predators, they ate other animals in the sea. They were cephalopods. These animals were protected by a shell (usually spiral-coiled) that contained many air filled chambers, called phragmocones; the animal lived only in the outer chamber. The opening of the shell is called the aperture. The walls of each chamber are called septa; these walls were penetrated by a ventral tubelike structure called a siphuncle that probably regulated the air pressure, allowing the ammonite to float.

| Grasping tentacles and eyes protruded from the opening on the outside of Euhoplites' coiled shell. The animal swam through the water in search of food—pushed along by a system of jet propulsion. A very fascinating fossil for it's size, Euhoplites has a deeply rippled shell pattern that more resembles a monster truck tire than an aquatic mollusk.
