Publisher's Synopsis
Excerpt from A Monograph on Carbonicola, Anthracomya, and Niadites
The fossils to be described in this Monograph are obtained, almost without exception, from the productive Coal-measures of the Carboniferous Series whether they occur, as in Scotland, the North of Ireland, and the North of England, at the base of this formation, as well as in the Coal-measures proper; or, as in the other coal-fields of Ireland, the remainder of England and Wales, and the Continent, above the Millstone-grit, in the upper beds. They chiefly occur in ironstone bands or nodules in indurated marl, and in black carbonaceous shales, and often in such profusion as to constitute shell-beds which extend over large areas. On the Continent it is found that the genera occurring in the Coal-measures pass up into beds of Permian age but it is doubtful at present whether it can be shown that the same species survived through both periods.
