Overview

Excerpt from A Catalogue of the Cretaceous Fossils in the Museum of Practical Geology The following catalogue contains lists of fossils beginning with the Neocom'ian or Lower Greensand series of strata, for long known as Lower Cretaceous beds, and these are succeeded in ascending order by lists of the fossils of the Gault, Upper Greensand, and the subdivisions of the Chalk. Occasionally some geologists have been in doubtas to the precise geological nomenclature that ought to be applied to some of the strata mentioned in this catalogue. One of these, the Blackdown beds, has been referred by different persons to the Upper Green sand, the Gault, and the Lower Greensand, in whole or in part. At first sight it appears from ordinary physical considerations that they form outlying patches of the Upper Greensand, the whole of this large outlier of Greensands being fragments of a much larger extension to the west of the Upper Cretaceous series, for they are in places west of the river Axe and Ilminster, capped by patches of Chalk, and it has often been assumed that, as they now stand, they have been simply separated by denudation from. The main body of the Upper Cretaceous series which forms the country from Dorsetshire to Beachy Head, the North Foreland, and Flamborough Head.
