Various aquatic reptiles were predators of ammonites. Fossils of damaged ammonites have been found with teeth marks from Plesiosaurs.
Ammonites lived in the oceans during the Mesozoic era, between 240-65 million years ago. They dwelled in various marine habitats, preferring areas with shallow waters and abundant food supply. Ammonites are extinct cephalopods characterized by their coiled shells.
Ammonites are the most widely known fossil. They are cephalopods and first appeared in the seas 415 million years ago, in the form of a straight shelled creature known as Bacrites. They do not have legs.

Some index fossils during the Triassic period include ammonites, conodonts, and certain marine reptiles like nothosaurs and thalattosaurs. These fossils are used by paleontologists to help date and correlate rock layers from that time period. They provide important information about the environments and life forms of the Triassic era.
