Uncovering the Enormous Marine Creatures of the Jurassic Era.
Paleontologists from the University of Portsmouth have discovered evidence suggesting that pliosaurs, closely related to the Liopleurodon, could have reached up to 14.4 meters in length, twice the size of a killer whale, after finding four large vertebrae in an Oxfordshire museum. Pliosaurs were at the top of the marine food chain and probably preyed on ichthyosaurs, long-necked plesiosaurs, and maybe even smaller marine crocodiles, simply by biting them in half and taking chunks off them. The discovery could prove that there was indeed a truly gigantic pliosaur species in the Late Jurassic seas.
