Covering a wide area of the London and Hampshire basins, the London Clay has been famous for over two hundred years as one of the richest Eocene strata in the country. In this work, first published between 1849 and 1858, Fellows of the Royal Society Richard Owen (1804-92) and Thomas Bell (1792-1880) describe their findings from among the reptilian fossils found there. The book is divided into four parts, covering chelonian, crocodilian, lacertilian and ophidian fossils, and includes an extensive section of detailed illustrations. Using his characteristic 'bone to bone' method and an emphasis on taxonomy, Owen draws some significant conclusions; he shows that some of Cuvier's classifications were wrongly extended to marine turtles, and adds to the evidence for an Eocene period much warmer than the present. The work is a fascinating example of pre-Darwinian palaeontology by two scientists later much involved in the evolutionary controversy.

These two short monographs, published under the auspices of the Palaeontographical Society in 1851 and 1854, show Charles Darwin as a meticulous research scientist, poring over fossils collected by himself and other enthusiasts in Britain and in Europe. The first volume is devoted to the Lepadidae, and the second to the Balanidae and Verrucidae (all types of barnacle, members of the infraclass Cirripedia). Darwin's interest in barnacles had first arisen in his student days in Edinburgh, under the guidance of Robert Grant, and increased during his detailed work in dissecting and classifying the specimens he had collected on the Beagle voyage. The publication of his findings cemented his reputation as a expert taxonomist and biologist, and his observations over eight years of the minute differences between males, females and an apparent hermaphroditic stage of development lent support to his developing theory of evolution.

This multi-part monograph by the geologist Searles Valentine Wood (1798-1880) covers more than 650 species and varieties of fossil mollusc found in the Pliocene-Pleistocene Crags of East Anglia. Illustrated with dozens of detailed plates, the work and its supplements originally appeared between 1848 and 1882.
