SOUTHAMPTON, ENGLAND—Flint tools discovered in Kent, along with the remains of a prehistoric elephant dating to around 420,000 years ago, were probably used to butcher the animal, according to Francis Wenban-Smith of the University of Southampton. It may even have been possible for early humans to have killed the very large creature with wooden spears. “Although there is no direct evidence of how this particular animal met its end, the discovery of flint tools close to the carcass confirm butchery for its meat, probably for at least four individuals,” he explained.
