Crocodiles - History

Crocodiles have arisen about 200 million years ago and outlasted the dinosaurs by 65 million years. Probably, it was thanks to water, where climatic changes were less intense. People failed to force into extinction any of 23 species of crocodilians, even when their impact has been appalling. The fossils of Crocodiles are identical to present-day Crocodiles. Crocodiles have a great chance to survive a nuclear winter and feed on the dead stuff while the rest of the fauna will die out.
