Acanthoceras Ammonite

Ammonoids were fascinating marine cephalopods that flourished in ancient oceans from the Devonian to the Cretaceous periods. Recognized for their distinctive spiral shells resembling a ram’s horn, their name originates from the Egyptian god Amun (or Ammon), who was depicted with ram’s horns. Although they share a similar shell shape with modern Nautiloids, Ammonoids are more closely related to today’s octopus, squid, and cuttlefish. These prehistoric creatures are prized by fossil collectors and paleontologists for their beauty, scientific significance, and insight into Earth’s ancient marine life.

Ammonoid shells were divided into internal chambers separated by walls known as septa. The junctions where these septa met the outer shell formed intricate suture patterns, which scientists use to classify different types of Ammonoids. Early forms, known as Goniatites, displayed a simple zigzag or “Goniatitic” suture pattern with smooth lobes and saddles. In contrast, later Ammonites evolved more complex, fern-like suture designs, reflecting their advanced evolutionary development. These stunning natural patterns make Ammonoid fossils both scientifically valuable and visually captivating for collectors and researchers alike.
