Acanthoceras Ammonite

Ammonoids were fascinating marine cephalopods that thrived in ancient oceans from the Devonian to the Cretaceous periods. Their iconic 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 appear similar to modern Nautiloids, their closest living relatives are actually octopus, squid, and cuttlefish. Today, Ammonoid fossils are prized by collectors and researchers alike for their beauty, scientific importance, and connection to Earth’s deep prehistoric past.

Ammonoid shells featured intricate internal designs, divided into multiple chambers by walls known as septa. Where these septa joined the outer shell, they formed beautiful and complex suture patterns—a key feature used to classify Ammonoids. Early species, called Goniatites, displayed a simple zigzag or “Goniatitic” suture pattern with smooth lobes and saddles. In contrast, later Ammonites evolved highly detailed, fern-like suture patterns, showcasing both artistic beauty and evolutionary advancement. These distinctive structures make Ammonoid fossils valuable to both scientists and collectors, offering insights into ancient marine life and Earth’s geological history.
