Aegirosaurus had a very long snout that made up 62 to 73 percent of its lower jaw length.1

Its front flippers were narrow and elongated, but its hind flippers were wide because of extra soft tissue.1

Aegirosaurus had a crescent-shaped tail fin, like a fish, to help it swim fast.1

Fossils of Aegirosaurus show skin impressions, including what might be tiny scales on the upper part of its tail fin.1

This ichthyosaur lived from the Late Jurassic to the Early Cretaceous, about 149 to 133 million years ago.3

Aegirosaurus is one of the few ichthyosaurs known from the Valanginian stage of the Early Cretaceous.1
