However, a detailed 2022 study of post-Anglian deposits in the Midlands estimates the age of the proto-Soar deposits ("Baginton sands") as around 150 ka - ie, as post-Anglian, not pre-Anglian. This reinforces the refutation hypothesis. See: Gibson SM et al, Timing and dynamics of Late Wolstonian Substage ‘Moreton Stadial’ (MIS 6) glaciation in the English West Midlands, UK, Royal Society Publishing, (Open access), June 2022. Reactions to this study are awaited.
