Utuntu dushimishije

1

Paraophthalmosaurus lived during the Tithonian age of the Late Jurassic, about 149 to 143 million years ago.1

2

Its name means 'near Ophthalmosaurus' because it was thought to be closely related to that other ichthyosaur.1

3

Scientists now think Paraophthalmosaurus might actually be the same as another ichthyosaur called Nannopterygius.2

4

The first fossils of Paraophthalmosaurus were found in a brick factory spoil heap in Gornyi, Russia.11

5

It had a femur (thigh bone) with three separate facets, which is a special feature that helps identify it.1

6

Like all ichthyosaurs, Paraophthalmosaurus gave birth to live young instead of laying eggs.1
