Description
Two halves showing well preserved internal structure. Ammonites are an extinct group of marine invertebrate animals of the class Cephalopoda. These molluscs are more closely related to living octopuses, squid, and cuttlefish than they are to the living Nautilus shell species.

Ammonites are excellent index fossils, and it is often possible to link the rock layer in which they are found to specific geological time periods.
The name ammonite was inspired by the spiral shape of their fossilized shells, which somewhat resemble tightly coiled rams' horns. Pliny the Elder (d. 79 AD. near Pompeii) called fossils of these animals ammonis cornua ("horns of Ammon") because the Egyptian god Ammon was typically depicted wearing ram's horns.
