A new fossil crocodile species has been discovered in Ethiopia, which is believed to have lived at the same time as the early human ancestor Australopithecus afarensis. The crocodile is described as large, potentially up to 15 feet in length, and may have preyed upon early humans. Reports suggest that this discovery provides insight into the environment and potential threats faced by early human ancestors, such as "Lucy", although the details of their interactions are still being explored.
