Giant crocodile dominates the ancient ocean

Their killer instincts are so scary that this creature is compared to the most famous killer of all time: the T-Rex dinosaur.

Scientists have discovered, topping the food chain in the European oceans 150 million years ago is a crocodile up to 6.8 m long, can tear the prey to death and a giant crocodile another giant drains its prey.

Plesiousuchus alligators have many similarities to skulls with T-rex.

These two prehistoric alligators have the scientific name Plesiosuchus and Dakosaurus , possessing hunting skills comparable to today's killer whales and Jurassic dinosaurs.

'The skulls of these two ocean crocodiles have many similarities with T-rex' , said University of Edinburgh scholar Mark Young with Discovery News. 'The largest skull ever found for Pleisiosuchus is approximately 1.3m in diameter, which is as big as the skull of an adult tyrant dinosaur'.

The size of two prehistoric ocean crocodile species.

Young and colleagues conducted fossil analysis of the two types of crocodiles mentioned above. They once dominated the entire sea around Europe, at the same time that Archaeooteryx dominated the European sky and Diplodocus and Allosaurus dinosaurs rained North America.

They came to the conclusion that Plesiosuchus is the largest ocean crocodile ever, larger than the brackish crocodile and the giant white shark. Their teeth have the same function as the teeth of modern killer elephants, allowing Plesiosuchus to bite both large and small prey.

However, the Dakosaurus itself is an unusual crocodile. Characteristics of the skull and jaw of the 4.5m long crocodile show that it is a blood-sucking animal. It also means that this is the first blood-sucking crocodile ever known in history.

Although there are many similarities, these two prehistoric crocodiles are not related to killer whales, because killer whales are mammals.
