Crocs rocked pre-Amazonian Peru: New research uncovers 7 crocodile species in single 13-million-year-old bone bed

Thirteen million years ago, as many as seven different species of crocodiles hunted in the swampy waters of what is now northeastern Peru, new research shows. This hyperdiverse assemblage, revealed through more than a decade of work in Amazon bone beds, contains the largest number of crocodile species co-existing in one place at any time in Earth’s history, likely due to an abundant food source that forms only a small part of modern crocodile diets: mollusks like clams and snails.
