First published in 1883, this study of the fossils of Upware and Brickhill originally appeared in 1879 as the Sedgwick Prize Essay for that year. Its author, Walter Keeping, was an expert in the Neocomian faunas of Cambridgeshire and Bedfordshire, and in this comparative study he examines the close palaeontological relationship between the Ironsand and Phosphatic series of fossils found at Upware, Potton, Brickhill, and Farringdon. He goes on to explore the resemblance of Upware oysters to Jurassic species, the distribution of Brachiopod shells, and the difficulties that arise when attempting to date fossils. Containing tables of vertebrate and invertebrate examples from England and Europe as well as an eight-plate section of detailed illustrations, this volume will be of value to anyone interested in geological and palaeontological studies from the nineteenth century.
