Pleistocene hominins at Happisburgh. Illustration of hominins butchering a deer at Happisburgh (now in Norfolk, UK) some 800,000 years ago, during the early part of the Pleistocene epoch. This scene is based on the discovery in 2013 of the Happisburgh footprints, fossilised footprints uncovered in a sediment layer on a beach. It is thought that the footprints were left by a small group of hominins (probably Homo antecessor). The area was the site of an ancient estuary, and had a climate similar to that of modern southern Scandinavia. Fauna included mammoths, giant deer, early horses, and hyenas. The hominins used flint tools and weapons.
