Crocodylus anthropophagus (man-eating crocodile)

We often hear about man-eating crocodiles, but Crocodylus anthropophagus gets its name from the fact that it was a predator of extinct hominids in Tanzania around 1.8 million years ago. This discovery points to greater diversity in African fossil crocodiles than previously thought.

The type material of Crocodylus anthropophagus is at the National Natural History Museum in Arusha, Tanzania. Other referred material is in the Natural History Museum, London, and other museums in the USA and Cuba.

    Behaviour and biology

    Crocodylus anthropophagus lived alongside early humans and probably had a similar biology to living African crocodiles.

Paranthropus (Australopithecus) boisei

The crocodile Crocodylus anthropophagus lived alongside small hominids such as Paranthropus (Australopithecus) boisei and Homo habilis. Fossil bones of at least 2 hominid individuals bear tooth marks characteristic of crocodile feeding. In both examples, each hominid lost its left foot in the encounter.
