Note 3 — Chapter III · ALLUVIAL DEPOSITS AND CAVES

The formation of the High Terrace drift is earlier than the date of arrival of the ‘Siberian’ invasion of Britain by certain Voles. Already in Pliocene times, some Voles had come into Britain from the south-east of Europe. But the Galley Hill man, if contemporary with the High Terrace drift, had arrived in Britain ages before the appearance of Homo aurignacensis supposed by Klaatsch to be closely allied, and to have come into Europe through Central if not Northern Asia. The ‘High Terrace’ mammals have a ‘Pliocene’ facies.
