Extract

The object of this paper is to describe and to figure accurately a remarkable double-ended rostro-carinate flint implement found by me during this year (1929) upon the north-east coast of Norfolk. The discovery was made upon the foreshore about mid-way between East and West Run ton, where at low water there are exposed considerable areas of the Basement Bed, resting upon the chalk, and referable to either the lowermost division of the Cromer Forest Bed or to the Stone Bed beneath the Norwich Crag. The implement was not found in situ in the Basement Bed, but was lying, with other stones, close to an exposure of this deposit. Apart, also, from this association, the specimen contains, in some of its interstices, portions of the highly ferruginous sand of the Basement Bed, while its colour and condition make it clear to those who are familiar with the stones in this deposit, that the implement at one time—and that recently—formed a part of it. The implement exhibits a typical mottled colouration consisting of areas of black, tawny brown and chocolate brown, while its ridges and outstanding portions show in most cases a rounded and somewhat broken-down appearance, which may be due to attrition by water-rolling, but which I am inclined to regard, as I have stated elsewhere, is to be accounted for by the action of some solvent present in the Basement Bed. The specimen exhibits but few incipient cones of percussion upon its flaked surfaces (which show a well-marked glaze), and cannot, therefore, have been subjected to collisions with other stones set in movement by running water. On the other hand a certain number of striae are to be observed upon the flake-scars of the implement, and these scratches not only, as it appears, cut into the patinated surfaces, but are in a weathered-out condition, thus showing that the flint was first patinated, then striated, and afterwards exposed to atmospheric effects.
