Insect faunas of the last glaciation from the Tame Valley, Warwickshire
Lenses of peaty sand occurring at the base of terrace gravels resting upon Keuper Marl in the Tame Valley, Warwickshire, England, have yielded large numbers of insect remains. Carbon-14 dating of the organic material gives an age of 32160 +1780 -1450 y B.P. The terrace gravels are broadly correlated...
