Alberta scientist finds massive crocodile-like fossil in Hungarian lake
It grew up to six metres long and its toothy mouth and crocodile-like body was the terror of ancient rivers and shorelines many millions of years ago.
Most mosasaurs were giant undersea predators, some growing up to 16 metres long, which breathed air but were full-time, fearsome sea creatures complete with paddle-like limbs similar to those of a whale. They lived around the same time as the dinosaurs and have been called the T. Rex of the sea.
“They were much bigger than T. Rex,” said Caldwell, an expert in mosasaurs. “They really were sea monsters.” (Tibor Pecsics)
