The sediments in which the footprints were made has been dated to over 800,000 years before present, and are the oldest known human footprints outside of Africa.[1][2][3] Prior to the discovery at Happisburgh, the oldest known footprints in Britain were at Uskmouth in South Wales, from the Mesolithic, and carbon-dated to 4,600 BC.[4]

Discovery

The footprints were discovered in May 2013 by Nicholas Ashton, curator at the British Museum, and Martin Bates from Trinity St David’s University. The footprints were found in sediment, partially covered by beach sand, on the foreshore at Happisburgh. The sediment underlies the cliff on the beach, and was exposed by erosion of the cliffs.[3] The footprints were recorded using photogrammetry, and within two weeks of their discovery they had eroded away.[5]

Description

The footprints of about five individuals have been identified, including both adults and children. The footprints measured between 140 millimetres (5.5 in) and 260 millimetres (10 in), which are thought to equate to heights of between about 0.9 metres (2 ft 11 in) and 1.7 metres (5 ft 7 in). It is thought that the species that made the footprints was Homo antecessor.[5]

Analysis shows that the group of about five individuals were walking together in a southerly direction along mudflats on the edge of an early version of the River Thames, which flowed into the sea further north than it does today.[5][6]
