Flint Implements of Upper Palæolithic Types from Glacial Deposits in Norfolk and Yorkshire

Abstract

MY researches in East Anglia have demonstrated that palæolithic flint implements occur in the glacial Boulder Clays of this region, and that these deposits, and their contained artefacts, are of widely differing ages. Thus, in the Tills overlying the Cromer Forest Bed of Norfolk, have been discovered specimens of Chellean type,¹ while, in what I term the Upper Chalky Boulder Clay of Suffolk, which appears to be separated from the Cromer Tills by a series of sands, gravels, and brick-earths, I have found specimens referable to Late Acheulean and to Early Mousterian times.² Upon the surface of the Upper Chalky Boulder Clay in the Ipswich district are situated, at certain places, two superposed and ancient occupation-levels yielding implements of Upper Mousterian and of Aurignacian types, and these floors are covered by a considerable thickness of hill-wash which, some years ago, I correlated with the latest glacial conditions obtaining in Suffolk.³
