Scientists have discovered two new crocodile species that lived between 18 and 15 million years ago and likely preyed on early humans, an advance that sheds more light on the evolution of the reptiles.
These crocodiles, which may have grown to over 3.5m (12 ft) in size, formerly inhabited east Africa between 18 and 15 million years ago before “inexplicably becoming extinct”, scientists from the University of Iowa in the US say.
