HOW BIG IT WAS

Paralegoceras relative size depiction as described below
The diameter of Paralegoceras was 8 cm.

Paralegoceras was an ammonoid – this group of cephalopods possessed coiled shells and were probably active predators or scavengers. Ammonoids almost died out in the Permian extinction but managed to recover and persist until the end of the Cretaceous period. As a group, cephalopods survived the Permian extinction and nautiluses, octopuses and squids still live in the oceans today. However the number and diversity of cephalopods were much reduced by the Permian extinction event.

A TRAIL THROUGH TIME

Cephalopods first appeared in the Silurian and survive to this day. See how this group has changed over time.
