The name literally translates to ‘flesh crocodile’. They look like crocs and alligators but last roamed the surface of the earth 112 million years in the past. These may be the largest amphibious reptiles that ever lived. They frolicked in the African continent during their time. Classified under the ‘Reptilia’ group and ‘Pholidosauridae’ family, they grew to lengths of nearly 3 times that of the largest crocs and weigh about 16,000 lbs. Their skulls are as large as full-grown humans.
