Explained: What is Pliosaur?

“They measured over 10 metres in length and could weigh up to several dozen tons. They had powerful, large skulls and massive jaws with large, sharp teeth. Their limbs were in the form of fins. We found bones of these pliosaurs in the north of the Swietokrzyskie Mountains,” palaeontologist Dr Daniel Tyborowski said in a statement released by Poland’s Ministry of Science and Higher Education.

In the Jurassic era, the Swietokrzyskie Mountains area is believed to have been an archipelago of islands, where there were warm lagoons and shallow sea reservoirs, home to the marine reptiles discovered by the palaeontologists.

The locality where the remains were discovered is considered to be rich in the fossils of coastal reptiles. Researchers now hope to find more remains in the coming months.
