A prehistoric crocodile dog named Montealtosuchus Arrudacamposi was discovered by Paleontologists. Said to be the "missing link" between prehistoric and present-day crocodiles, this predator measured 1.5-1.7 metres and weighed about 40 kilograms and lived in the late Cretaceous Period in the region of Palo Alto, in Sao Paulo state, Brazil.

Although it has no genetic link to mammals, the creature's stocky build and long snout are uncannily similar to the features of a large dog.

Federal University of Rio de Janeiro paleontologist Felipe de Vasconcellos, who helped research the fossil found in 2004, said the reptile's physical characteristics placed it between prehistoric crocodiles and their current descendants.

It lived on dry land and was quick on its feet, instead of living in marshlands and spending most of its time under water, he said.

"Its nostrils were at the front (of its snout). If it went in the water it had to keep its head erect making it an easy target for other predators. Its eyes were placed laterally, like other land-walking animals," Mr Vasconcellos said.
