POSTI IMI

The amphibian, with hundreds of teeth in a flat head like a toilet seat, took the place of crocodiles as a top predator over 200 million years ago. 
Fossil remains of Metoposaurus algarvensis, were found at the site of an ancient lake in south Portugual. 
Edinburgh University’s Dr Steve Brusatte led a study published in the Journal of Vertebrate Paleontology. He said: “This new amphibian looks like something out of a bad monster movie. 
"It was as long as a small car and had hundreds of sharp teeth in its big flat head, which kind of looks like a toilet seat.” 
Co-author Dr Richard Butler, from the University of Birmingham, said: “These giant predators would have made lakes and rivers pretty scary places to be.”
