Acanthoplites is an extinct genus of cephalopod belonging to the Ammonite subclass. Like many other Ammonites, Acanthoplites was a marine nektonic carnivore.

Fossil Record[edit]

The most commonly preserved remains of Acanthoplites are the animals' shells, which were composed of Aragonite. This animal first appears in rocks dating to the late Aptian portion of the Cretaceous Period. This means that Acanthoplites fossils are 112-125 million years old. No fossils of Acanthoplites have been found post-dating the Aptian. Remains from this genus have been found on multiple continents in the nations of Mexico, Argentina, Morocco and South Africa
