A complex of channels underlying the Baginton-Lillington Gravel (Baginton Formation) at Waverley Wood Quarry, Warwickshire is described. Fossil pollen and plant macrofossils, Coleoptera, Ostracoda, Mollusca and Mammalia are described from the channelfill deposits. Consideration of all the evidence allows the identification of four separate stages of channel fill which largely occurred under a cool temperate climate. At the top of Channel 2 evidence for a cold, continental climatic episode can be recognised, suggesting that the whole complex was deposited under a fluctuating climate at the end of a temperate stage. At two levels in the channels human artefacts were recovered confirming the presence of Palaeolithic people in Warwickshire during the deposition of the sediments. Amino-acid geochronology suggests an age within the 'Cromerian Complex' Stage for the channels. The small vertebrate and molluscan faunas indicate that the deposits are no older than the latter part of the 'Cromerian Complex' Stage of East Anglia.

SummaryThe lithostratigraphical division of the Wolstonian Stage of the British Pleistocene is reviewed in the light of borehole records along the line of the M 69 motorway. The Wolston Clay is divided into 5 members. The evidence from the M 69 shows that 2 periods of glacier advance were separated by a major period of recession of the order of 104 years, in which most of the sediments of Glacial Lake Harrison were deposited. It is argued that this recession was interstadial rather than interglacial.
