Acanthoceras Ammonite

Ammonoids were an extinct group of marine cephalopods that thrived in Earth’s oceans from the Devonian through the Cretaceous periods. Their 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 they resemble modern Nautiloids, Ammonoids are more closely related to octopus, squid, and cuttlefish.

Their shells were divided into internal chambers by thin walls called septa, and where these septa met the outer shell, they formed intricate suture patterns used to classify different species. Early Goniatites displayed simple zigzag or “Goniatitic” suture patterns with smooth lobes and saddles, while later Ammonites evolved highly complex, fern-like designs. These stunning natural patterns make Ammonoid fossils both scientifically valuable and visually captivating, offering a fascinating glimpse into prehistoric marine life.
