By the start of the Jurassic period (about 200 million years ago), crocodiles had mostly abandoned their terrestrial lifestyles, probably as a response to the terrestrial dominance achieved by dinosaurs. These reptiles, distant relatives of dinosaurs, survived because they were able to adapt to the new environment. The largest dinosaur was the Tyrannosaurus rex, which was about the size of a house cat. Dr Stockdale, a geographical scientist, said: 'Our analysis used a machine learning algorithm to estimate rates of evolution.

In territorial fights they commonly tear each other's legs off. New research by UK scientists at the University of Bristol adds to evidence that the mighty crocodile has existed largely unchanged for 200 million years, having outlasted the dinosaurs and countless other plant and animal species that were wiped out by an asteroid that smashed into the Yucatn Peninsula 66 million years ago.

For example, a crocodile that has been exposed to a temperature of -20C for a period of 24 hours will begin to show signs of hypothermia.
