Uncovering the Massive Fossilized Sea Monster Twice the Size of a Killer Whale.

Palaeontologists from the University of Portsmouth have discovered the fossil of a new species of prehistoric marine reptile that could have been twice the size of a killer whale. The fossils, which are vertebrae belonging to a pliosaur, suggest that these animals could be much larger than previously thought, adding to a debate that has divided experts for some time. The pliosaur was a large, fearsome marine predator that lived during the Late Jurassic era, around 145-152 million years ago. The study was published in Proceedings of the Geologists’ Association.
