Stenopterygius was a fast-swimming marine reptile that lived in the Jurassic seas. It looked a bit like a dolphin but was actually an ichthyosaur, not a dinosaur. It had a long beak full of teeth and chased after fish and squid.1

Stenopterygius had a small skull and narrow flippers compared to its relative Ichthyosaurus.1

One well-preserved fossil shows traces of skin, revealing that Stenopterygius was countershaded: darker on the back and lighter on the belly.1

Fossils of Stenopterygius often contain the remains of its last meal in the stomach area.1

The tail ended in a large, semicircular, leathery vertical fin, and it also had a triangular dorsal fin on its back.1

Stenopterygius lived during the Early and Middle Jurassic, about 183 to 173 million years ago.1

The type specimen of Stenopterygius quadriscissus is a complete skeleton that even preserved a very large embryo inside.1

?What did Stenopterygius eat?

Stenopterygius hunted fish, cephalopods, and other animals in the open sea. Fossils often contain the remains of its last meal in the stomach area.1

?Was Stenopterygius a dinosaur?
