Paleontologists from the University of Edinburgh found the so-called "super salamander" in southern Portugal, at a site where there had once been a lake. The predator species, Metoposaurus algarvensis, could reach up to six feet in length and lived about 220 million years ago.
Scientists believe the amphibian lived in lakes and rivers and ate a diet consisting primarily of fish. The species, which had hundreds of teeth, was a predator while dinosaurs were still evolving. The findings are described in the latest issue of the the Journal of Vertebrate Paleontology.
