These molluscs are more closely related to living coleoids (i.e., octopuses, squid, & cuttlefish) than they are to shelled nautiloids such as the living Nautilus species.[citation needed] The earliest ammonites appear during the Devonian, & the last species died out during the Cretaceous-Paleogene extinction event. Ammonites are excellent index fossils, & it is often possible to link the rock layer in which a particular species or genus is found to specific geologic time periods. Their fossil shells usually take the form of planispirals, although there were some helically spiraled & nonspiraled forms (known as heteromorphs). The name “ammonite”, from which the scientific term is derived, 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 (Amun) was typically depicted wearing ram’s horns.[1] Often the name of an ammonite genus ends in -ceras, which is Greek (κέρας) for “horn”.
