Massive marine reptiles that fed on just about anything they came in contact with. Abundant during the latter part of the Cretaceous but wiped out with the Dinosaurs.

'Dolphin like' marine reptiles that were around for a similar duration to the Dinosaurs. Normally fossils available from the Jurassic but they appeared in the Triassic and died out before the end of the Cretaceous. Spectacular complete specimens collected from the 'Jurassic coast' in the UK are on display in museums around the world.
