IV.—The Lower Lias of Leicestershire

Published online by Cambridge University Press:  01 May 2009

Extract

The Lower Lias in Leicestershire commences with clays and limestones (Strenshain Series), succeeded by clays and shales. In its palasontological characters, as well as in its petrological features, it agrees in the main with the Lias of contiguous districts. The following life-zones are apparently represented, viz. zones of Ammonites planorbis, angulatus, Bucklandi, semicostatus, oxynotus, armatus, Jamesoni and capricornus.
