English: The enormous freshwater turtle, that existed around 60 million years ago, is depicted here having just snapped up a crocodylomorph from a patiently awaited lakeside ambush. The adult turtle would have been about the same size as a Smart car, and the shell could have been inverted and used as a kiddie pool. Fossil evidence suggest that the jaws were very powerful and most likely would have crushed mollusks and crocodiles with a single snap. Its large size would have made it virtually impervious to attack from the larger crocodillian species of the era. The turtle evolved in a period after the dinosaurs. This is only an artistic depiction since there is not much fossil remains at this time.
