largest reptile ever

[StuartDH]

anyone know what was the largest reptile ever to live on planet earth...I say that because I remember watching some star treks as a kid where they had some massive reptiles on other planets

Not sure what the biggest reptile would have been, but I do know that in Maastricht in the caves/quarries there have been two skeletons found of huge crocodile like animals, Mosasaurus (lizard of the Maas) hoffmanni. The larger of the two was 15 metres, so maybe the largest or at least on of the largest reptiles to roam western Europe?

The largest living reptile is the Australian Saltwater Crocodile (Crocodylus porosus). Largest confirmed adult male reaching 20.6 feet in length, some claims of ones reaching 23ft, but most *only* reach around 17ft.
An extinct relative of the modern Gharial called Rhamphosuchus had an estimated length of 50-60 ft.

The largest extinct Marine Reptile is a Pliosaur. A 150-million-year-old specimen was discovered in Svalbard in 2006 and analyzed at the Natural History Museum at the University of Oslo. It is estimated to be 50 feet long with 10-foot-long flippers.
