Description
Their shells had ornate ribs whose function is unknown, although some scientists have speculated that these ribs helped strengthen the animals' shells to allow them to live at greater depths where the water pressure is higher. An adult had a shell diameter of approximately 100 centimetres (39 in).
Distribution
Acanthoceras fossils can be found in Western Europe, western North America and northern Australia.
