The Clacton (Essex) Channel Deposits

Abstract
New field evidence of the Clacton channel deposits i3 recorded. A general revision of the non-marine mollusca by the late A. S. Kennard and Mr. C. P. Castell points to the same invasion of Rhenish species that Kennard found in the middle of the Swanscombe sequence. The marine mollusca of the estuarine stage include nothing to distinguish them from the Holocene, although the rest of the biotope points to the mid-Pleistocene.
