Brachypterygius
Brachypterygius was a fast-swimming marine reptile that lived in the Late Jurassic seas. It looked a bit like a dolphin but was a reptile, not a fish or a dinosaur. Its short, wide front flippers helped it steer through the water.1

Datu dibertigarriak
Brachypterygius had a short, wide front flipper with up to six fingers, and some fingers had as many as 16 bones.1
Its skull was between 0.5 and 1.2 metres long, about the size of a big dog's head.1
The first fossil of Brachypterygius was just a single right front flipper, found in England.1
Brachypterygius lived during the Kimmeridgian and Tithonian ages, about 154 to 143 million years ago.3
It is closely related to other ichthyosaurs like Platypterygius and Caypullisaurus.1
Scientists once thought Brachypterygius was the same as another ichthyosaur called Grendelius, but now many think they are different.1

- The first fossil, a right front flipper, was described as Ichthyosaurus extremus by Boulenger in 1904. In 1922, Friedrich von Huene gave it the new name Brachypterygius because of its short, wide flipper.1

- Scientists still debate whether the species Grendelius mordax is the same as Brachypterygius extremus or a separate animal.1
