A study led by scientists at the American Museum of Natural History has resolved a long-standing controversy about an extinct “horned” crocodile that likely lived among humans in Madagascar. Based on ancient DNA, the research shows that the horned crocodile was closely related to “true” crocodiles, including the famous Nile crocodile, but on a separate branch of the crocodile family tree. The study, published today in the journal Communications Biology, contradicts the most recent scientific thinking about the horned crocodile’s evolutionary relationships and also suggests that the ancestor of modern crocodiles likely originated in Africa.
