Behaviour and biology


This crocodile lived alongside the early humans Homo habilis and Paranthropus (Australopithecus) boisei.

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.


Crocodylus anthropophagus probably had a similar biology to living African crocodiles.

Crocodile embryos do not have sex chromosomes, and unlike humans, sex is not determined genetically. Sex is determined by temperature:

  • males are produced at around 31.6°C
  • females are produced at slightly lower and higher temperatures
