“They’ve done some extensive excavations and geological studies, and they’ve done a tremendous job integrating a variety of dating techniques to show very tight age constraints for that fossil bed and by inference the last appearance of Homo erectus,” says Rick Potts, a paleoanthropologist and head of the Smithsonian’s Human Origins Program.
