Ammonite (Mammites nodosoides)

A Creataceous fossil ammonite (Mammites nodosoides) from Morocco.

Ammonites were marine creatures that lived millions of years ago, during the Paleozoic and Mesozoic Eras. They were distant relatives of modern-day octopuses and squids, and their fossilized shells are often found in sedimentary rocks.

Mammites nodosoides is a fascinating Late Cretaceous ammonite from the Turonian stage (approximately 90 million years ago), commonly found in the Atlas Mountains of Morocco and other regions like Tunisia and Texas. It has a distinctive coiled shell with strong ribs and prominent tubercles and belongs to the Acanthoceratidae family, known for heavily ornamented shells. The complex ammonitic sutures—intricate, frilled patterns where chamber walls meet the shell—suggest a strong, buoyant structure adapted to withstand deep-sea pressures. Fossils of this species often show a robust, globular shape with a wide umbilicus (central opening).
