Great Geologists | 33 rhinoceros, as well as animals such as hyena that no longer occur in Europe. In a brilliant study of forensic paleontology he showed that the bones had been accumulated by hyenas that used the cave as a den. He reconciled this with his flood hypothesis by noting that the bones were buried in waterlain silt which he attributed to the Great Deluge and which led to the extinction of some species. Also in 1823 Buckland discovered a red- stained skeleton in Paviland Cave in South Wales which he named the Red Lady of Paviland. First supposing it to be the remains of a local prostitute he then noted that it occurred in the same strata as the bones of extinct mammals (including mammoth), Buckland shared the view of Georges Cuvier that no humans had coexisted with any extinct animals, and he attributed the skeleton’s presence there to a grave having been dug in historical times, possibly by the same people who had constructed some nearby pre-Roman fortifications, into the older layers. In fact, although it post-dates the mammoth remains, it is the oldest anatomically modern human found in the United Kingdom. Carbon-data tests have since dated the skeleton, now known to be male, as from circa 33,000 years before present (BP). Original illustration of the Megalosaurus jaw by Buckland’s wife Mary. Through the 1820’s Buckland began to realize that the fossil record suggested a more complex view of Earth history than a simple relationship with the great flood. Following the evidence documented by William Smith, Georges Cuvier and others he realized that there was a stratigraphic organization to the fossil record which contained many extraordinary creatures that have no direct counterpart today. This included the fossil ichthyosaurs and plesiosaurs being found by Mary Anning on the Dorset coast and in 1824 his own analysis of the jaw of what he considered an extinct giant lizard – Megalosaurus, later classified as a dinosaur by Richard Owen. This was found by workmen at a quarry in Stonesfield, not too distant from his college rooms in central Oxford. By 1836 he had recognized that the fossil record represented a succession of distinctive past ecosystems and summarized this in his seminal book Idealised geological cross-section across Europe produced by Buckland in 1836 (in Geology and Mineralogy considered with reference to Natural Theology) illustrating the general succession of strata and their constituent assemblages of fossils. Igneous and metamorphic activity is also highlighted.
