Liopleurodon(Lie-oh-ploor-oh-don), Smooth sided teeth, was a pliosaur; the tiger of the sea, preying on sharks, large squid and ichthyosaurs. Two species of Liopleurodon lived during the Callovian stage of the Middle Jurassic Period, while the third, L. rossicus, lived during the Late Jurassic. The largest species, L. ferox, is estimated to have grown up to 21 feet in length (Dixon, 2006).
Liopleurodonwas a powerful swimmer but not a speedy swimmer. It had four flippers; the front paddles were used to steer while the back acted like wings. This method allows for very good acceleration. The skull and jaws take up one fifth of the total length of the body. The arrangement of the nostrils suggests they were not used for breathing but to taste the water. This could enable Liopleurodon to taste the water, perhaps following the blood of fresh kills.
LENGTH: 6 – 7.5 m (33 ft).
WEIGHT: 7 tons.
As the apex predator, it preyed upon other marine reptiles, sharks and the giant fish of the Jurassic. Ichthyosaur fossils show evidence of having been torn to pieces by a large pliosaur.
