IV.—The Northfleet 50-foot Submergence later than the Coombe Rock of post-Early Mousterian times

Abstract

Researches conducted during the past twenty years have definitely succeeded in establishing the sequence, both archaeological and geological, of the Boyn Hill or ‘100-foot’ terrace of the Lower Thames. The culture-stages there represented are set out hereunder in ascending order, beginning with the oldest:(1) Clactonian 1; these specimens, many of which are striated, have been derived from some earlier deposit not yet located :(2) Clactonian 2 and 3 :(3) Acheulian :(4) Early Mousterian (Levalloisian A of mid-Pleistocene times).
