Acanthoceras Ammonite

Ammonoids were an extinct group of marine cephalopods that thrived in Earth’s oceans from the Devonian through the Cretaceous periods. Their distinctively coiled shells, shaped like a ram’s horn, inspired their name—derived from the Egyptian god Amun (or Ammon), who was depicted with ram’s horns. Although Ammonoids resemble modern Nautiloids, their closest living relatives are actually octopus, squid, and cuttlefish.

The shells of Ammonoids were divided into internal chambers by thin walls called septa. The points where these septa joined the outer shell formed intricate suture patterns, which are used to classify different Ammonoid species. Early forms, known as Goniatites, displayed a simple zigzag or “Goniatitic” suture pattern with smooth lobes and saddles. Later Ammonites, however, evolved highly complex, fern-like suture designs, reflecting both their advanced evolution and natural beauty.
