| Abstract |
The mollusc fauna is studied qualitatively and quantitatively. The fauna, as well as the lithofacies, indicate the following sequence (from top to bottom) : -sandy beach deposits with shell accumulations (bed C) ; -finely grained sediments, probably deposited in an intertidal Zone; fauna much comparable with that of the actual Dutch "Waddenzee" (bed D) ; -sublittoral, sandy deposits. Transgressive phase. Climate probably slightly warmer than that of the actual Belgian Coast. Possible Eemian age (bed E). A statistical study of Amygdala collected from bed E is included. The variation in length of specimens of this bivalve is greater than the combined variation of the same measurement in A. aurea and A. senescens. It is also shown that hand picked samples of Amygdala differ markedly from sieved samples in mean dimensions. In view of the foregoing, the only diagnostic criterion separating A. aurea and A. senescens appears useless, and both species have been lumped under the name Amygdala aurea (Gmelin, 1791) (= Venerupis aurea; Paphia aurea). |
