Isle of Wight: History
=== Stone Age ===
During Pleistocene glacial periods sea levels were lower than at present, and the area that today forms the Solent was part of the valley of the now-extinct River Solent. The river flowed eastward from Dorset, following the course of the modern Solent strait. The river travelled east of the Isle of Wight before flowing southwest towards the major Channel River system. At these times, extensive gravel terraces associated with the Solent River and the forerunners of the island's modern rivers were deposited. During warmer interglacial periods, silts, beach gravels, clays, and muds of marine and estuarine origin were deposited due to higher sea levels, suggesting similar marine or estuary conditions to those experienced today.
The earliest clear evidence of Lower Palaeolithic archaic human occupation on what is now the Isle of Wight is found close to Priory Bay. More than 300 acheulean handaxes have been recovered from the beach and cliff slopes, originating from a sequence of Pleistocene gravels dating approximately to MIS 11-MIS 9 (424,000–374,000 years ago). Reworked and abraded artefacts found at the site may be considerably older however, closer to 500,000 years old. The identity of the hominids who produced these tools is unknown. However, sites and fossils of the same age range in Europe are often attributed to Homo heidelbergensis or early populations of Neanderthals.
A Middle Palaeolithic Mousterian flint assemblage, consisting of 50 handaxes and debitage, has been recovered from Great Pan Farm in the Medina Valley near Newport. Gravel sequences at the site have been dated to the MIS 3 interstadial during the last glacial period (c. 50,000 years ago). These tools are associated with the late Neanderthal occupation, and evidence of late Neanderthal presence is seen across Britain at this time. …
