Pervushovisaurus

Pervushovisaurus was first thought to be a type of Platypterygius, but scientists later decided it was different enough to be its own genus.1

This ichthyosaur had a straight snout, unlike some of its relatives that had curved jaws.1

Its teeth had square roots with sharp 90-degree angles, which is unusual for an ichthyosaur.1

One species, Pervushovisaurus campylodon, was originally named Ichthyosaurus campylodon in 1846.1

Pervushovisaurus lived during the Cretaceous period, at the same time as dinosaurs like Tyrannosaurus and Triceratops, but in the ocean.3

Fossils of Pervushovisaurus have been found in the Melovatka Formation in Russia and the La Penthiève Beds in France.1

Like other ichthyosaurs, Pervushovisaurus gave birth to live young, not laying eggs on land.2
