Modern-day ammonites do not exist, as they are an extinct group of marine mollusks that thrived during the Mesozoic Era. They are closely related to today's cephalopods, such as squids and octopuses. While ammonites themselves are gone, their lineage has evolved into various living cephalopod species, which inhabit oceans worldwide.
mostly fish, but also mollusks such as ammonites
Ammonites were marine animals that likely fed on small fish, plankton, and other small marine creatures. The shape of their jaws and radula suggest a diet of soft-bodied organisms.
ammonites are extinct
They would prey on free-swimming, armored prey like arthropods, ammonites, and other placoderms.
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 named for the Egyptian god Ammon, who had a ram's head. The shells of ammonites are spirals like the horns of a ram.
Various aquatic reptiles were predators of ammonites. Fossils of damaged ammonites have been found with teeth marks from Plesiosaurs.
Squid
Ammonites first appeared during the Devonian Period within the Paleozoic Era.
Ammonites went extinct at the end of the Cretaceous Period.
Ammonites went extinct at the same time as the dinosaurs, about sixty-five million years ago.
Ammonites are very common fossils from the Jurassic Period. They were dominant in the ocean during and before the Jurassic Period.
