Datos curiosos
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

- The first fossil was named Ichthyosaurus leptospondylus by Wagner in 1853. In 2000, scientists Bardet and Fernández gave it the new genus name Aegirosaurus after studying a nearly complete skeleton with soft tissue impressions.12
- Aínda en debate
- Scientists are not sure whether Aegirosaurus had scales on its tail fin, because only one fossil shows possible scale impressions.1
