In 2006 his team uncovered an enormous short-necked plesiosaur, the Pliosaurus funkei, possibly the largest carnivore found to date.
The large pliosaurs, like the Jurassic Rhomaleosaurus, Liopleurodon and Pliosaurus, and the Cretaceous Kronosaurus and Brachauchenius, were the superpredators of the Mesozoic seas, around 7 to 12 meters in length, and filled a similar ecological role to that of killer whales today.
