Paraophthalmosaurus
Paraophthalmosaurus was a fast-swimming marine reptile that lived in the Late Jurassic seas. It looked a bit like a dolphin but was actually an ichthyosaur, not a dinosaur. It had a long snout and big eyes to hunt fish and squid.12

Prettige feite
Paraophthalmosaurus lived during the Tithonian age of the Late Jurassic, about 149 to 143 million years ago.1
Its name means 'near Ophthalmosaurus' because it was thought to be closely related to that other ichthyosaur.1
Scientists now think Paraophthalmosaurus might actually be the same as another ichthyosaur called Nannopterygius.2
The first fossils of Paraophthalmosaurus were found in a brick factory spoil heap in Gornyi, Russia.11
It had a femur (thigh bone) with three separate facets, which is a special feature that helps identify it.1
Like all ichthyosaurs, Paraophthalmosaurus gave birth to live young instead of laying eggs.1
