If you think of a newt, how big an animal are you imagining? Maybe the side of a human hand? Researchers in Europe say there used to be one that was the size of a car.

FOX News Radio's Simon Owen reports from London.

Never mind the kind of animals you see in 'Jurassic Park'. The first dinosaurs would have been terrorized by this newt, according to researchers in Edinburgh, Scotland.

They say they've found fossil remains in Portugal, of a giant amphibian that roamed lakes and rivers more than 200 million years ago.

They say it looked like something out of a bad monster movie. With hundreds of teeth, and a flat head which looked like a toilet seat when its jaws snapped shut.

The newts were wiped out in a mass extinction -- the same one that paved the way for dinosaurs to take over the Earth.
