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. The words ammonite and ammonoid are both used quite loosely in common parlance to refer to any member of subclass Ammonoidea. However, in stricter usage the term ammonite is reserved for members of suborder Ammonitina (or sometimes even order Ammonitida).
