Published online by Cambridge University Press: 01 May 2009
Abstract
The marine Johnstone Shell Bed, an important index horizon in the Limestone Coal Group of the Carboniferous of Scotland, is succeeded in North Ayrshire by a bed containing Lingula squamiformis Phillips, and many small shells here referred to a new species of the genus Carbonicola. This Carbonicola community has been examined in detail, and graphical representation of the great variability has been employed.
