Extract

During a recent examination of the Carboniferous Limestone in the Dove Dale district I have met with an abundance of Productus humerosus. This species is a common fossil in the cliffs extending for a distance of quite 2 miles from the top end of Nabs Dale to beyond Tissington Spires. It is most prolific at and near Reynard's Cave, where the shells occur in clusters, often cupped into each other.
