A newfound crocodile had a body as long as a bus and a head as large as a man. It belongs to a previously unknown species of crocodile and was discovered by paleontologists in Tunisia.

It was nearly 10 meters long (32 feet), with a weight around 3 tons (6,000 pounds).

This species existed during the early Cretaceous period 130 million years ago and has been given the Latin name Machimosaurus rex. It is the largest known ocean-dwelling marine reptile to have ever existed.

It was not as long as some of their later freshwater relatives, however. Sarcosuchus imperator lived some 110 million years ago, and it is the largest known freshwater crocodile to have ever existed. It could be up to 12 meters long (39 feet) and weigh about 8 tons 16,000 pounds).

The largest thalattosuchian (Crocodylomorpha) supports teleosaurid survival across the Jurassic-Cretaceous boundary
