The Jurassic Rocks of the Neighbourhood of Cambridge

Cambridgeshire is rich in Jurassic fossils, with ichthyosaurs having been found at Mepal and Barrington since 2000, and ammonites and belemnites occurring near Grafham Water. In the later nineteenth century, Thomas Roberts, an assistant to the Professor of Geology at Cambridge, was involved in close study of the Jurassic rocks of the district.
