Too Big to Walk. Brian J. Ford

continued to attract interest, and in 1796 Thomas Jefferson (who became the president of the United States just five years later) sent a small expedition to look for extinct mastodons and mammoths near the Ohio River in Kentucky. Like most well-educated statesmen of his time, Jefferson liked to keep abreast of discoveries in natural history and science. Indeed, when the White House was first built, it was furnished with a ‘Mastodon Room’ to house fossil collections. In 1797, Jefferson gave a presentation at the American Philosophical Society in Philadelphia, describing a fossilized giant sloth that now bears his name: Megalonyx jeffersonii. When the presentation was printed as an academic paper in the Society’s journal, it became one of the first American publications in the developing field of palæontology.20 More recent American presidents are perhaps less likely to publish academic papers in scholarly journals.

      Dinosaur footprints were now being discovered by new arrivals in the United States. The first we know about were unearthed in 1802 by a farm boy named Pliny Moody of South Hadley, Massachusetts. Moody dug up a slab of red sandstone while ploughing. It showed some small, sharp, clear, three-toed footprints. This fine specimen was fixed above the farmhouse door, where a local physician confidently identified them as being the tracks of Noah’s raven. The story of the biblical flood was still the conventional explanation at the time, because there was no understanding of fossil footprints left by dinosaurs, so although it seems fanciful to us, this was a popular diagnosis at the time. We are quick to ridicule such early conventions, though a glance at today’s religious television channels reminds us that present-day beliefs can be as superstitious and fanciful as anything we have seen in the past.

      The Napoleonic Wars had been raging in Europe and they finally ended in 1815, whereupon Georges Cuvier seized the opportunity to visit England. One of his first ports of call was to meet William Buckland in Oxford. Buckland was born on March 12, 1784, in Axminster, Devon, and spent much of his time as a child walking across the countryside with his father, the Rector of Templeton and Trusham. His father used to show him how to collect fossilized shells, including ammonites, from the strata of Jurassic Lias that were exposed in the quarries. The young Buckland went to school in Tiverton, and eventually entered Corpus Christi College at Oxford University, to study for the ministry. He regularly attended lectures on anatomy given by Christopher Pegge, a physician at the Radcliffe Infirmary in Oxford, and he was particularly intrigued by part of a fossilized jawbone that Pegge had purchased for 10s 6d (now about £40 or $55) in October 1797. Buckland also went to the presentations given by John Kidd, Reader in Chemistry at Oxford, on subjects ranging from inorganic chemistry to mineralogy, and discovered that Kidd had himself collected several fragments of huge bones from the Stonesfield Quarry near Witney, some 10 miles (16 km) away. The plot was thickening.

      Buckland meanwhile continued searching for fossil shells in his spare time. These he initially took as evidence of the biblical story of the flood, but as the years went by he turned towards more scientific reasoning and abandoned the literal truth of the Old Testament. After graduating, he was made a Fellow of Corpus Christi College, Oxford, in 1809, and he was formally ordained as a church minister. In 1813 Buckland was given the post of Reader in Mineralogy, following John Kidd, and his dynamic and popular lectures began to include a growing emphasis on palæontology. By now he was becoming an experienced collector, and in 1816 he travelled widely in Europe, including Austria, France, Germany, Italy, Poland and Switzerland. He visited Cuvier on several occasions.

      Buckland became something of an eccentric. He always wore an academic gown instead of overalls for his fieldwork and claimed to have devoured his way through most of the animal kingdom, serving mice, crocodiles and lions to his guests (and he claimed that the two foods he disliked most were moles and houseflies). On his travels, he was said to have been shown the preserved heart of King Louis XIV nestling in a silver casket and remarked: ‘I have eaten many strange things, but have never eaten the heart of a king before,’ and so he picked it up and bit into it before anybody could stop him.

      Buckland’s first major prehistoric discovery was not of a reptile, but a human – the Red Lady of Paviland, a human skeleton found in South Wales. He decided to explore the largely inaccessible Paviland cave on January 18, 1823, only to find this well-preserved skeleton, which he initially took to be the corpse of a local prostitute. He later concluded that the body had been placed there by early residents in pre-Roman times, though more recent tests have shown that it dates back 33,000 years – indeed, it is now accepted as the most ancient human skeleton ever found in Britain. Buckland married an enthusiastic fossil collector and accomplished artist, Mary Morland, in 1825, and thereafter Mary devoted herself to illustrating her husband’s palæontological publications with flair and skill.

      By the time of Cuvier’s visit, Buckland was studying fossil collections, and among the specimens he showed to his French visitor were the Scrotum humanum and Pegge’s curious specimen of a fossilized jawbone. Cuvier concluded that these were both fragments from gigantic reptiles. William Conybeare, a palæontologist colleague of Buckland’s, referred to these specimens as the remains of a ‘huge lizard’ for the first time in 1821, and the physician and fossil hunter James Parkinson soon announced his intention to call the creature Megalosaurus from the Greek μέγας (megas, large). Parkinson estimated that this had been a huge land animal measuring 40 feet long and 8 feet tall (12 x 2.5 metres). Parkinson is little known today as a palæontologist, though we all know his name in a different context – he is the physician who correctly identified the degenerative disease known, in his time, as a ‘shaking palsy’ and which we now call Parkinsonism. Most palæontologists at the time were physicians, and many made discoveries that resonate beyond the world of the fossil collector.

      Buckland now faced urgent demands from Cuvier for details to include in his own book, and meanwhile Buckland continued to investigate the fossil remains, while his wife Mary began preparing the detailed drawings of the remains for publication that were to be the basis of the published lithographic plates. Buckland had met Mary while travelling by horse-drawn coach in the West Country. An account records:

      Both were travelling in Dorsetshire and each were reading a new and weighty tome by the French naturalist Georges Cuvier. They got into conversation, the drift of which was so peculiar that Dr. Buckland exclaimed, ‘You must be Miss Morland, to whom I am about to deliver a letter of introduction.’ He was right, and she soon became Mrs Buckland. She is an admirable fossil geologist, and makes midels in leather of some of the rare discoveries.21

      They worked together diligently in every spare moment they could find. There was now growing interest in the fossils being found at Lyme Regis on the Dorset coast of southern England. Most people believed these rocky remains to be the fossils of familiar fauna (crocodiles or dolphins). Collectors including Henry de la Beche and William Conybeare carefully examined a range of specimens, and published a joint account in 1821 concluding that they might represent something very different – a new kind of reptile. They mentioned the work of a host of amateur collectors, acknowledging ‘Col. Birch, Mr. Bright, Dr. Dyer, Messrs. Miller, Johnson, Braikenridge, Cumberland, and Page of Bristol,’ and they now concluded that this new type of reptile formed a bridge between ichthyosaurs and crocodiles, and so they coined a new term for these creatures: plesiosaurs.22

      Interest in the fossil reptiles started to spread, and in 1822 James Parkinson published a book on his investigations entitled Outlines of Oryctology, which, although primarily concerned with seashells and other familiar fossils, also reported the latest investigations of the huge reptile fossils that were now beginning to appear. In this book, Megalosaurus was included as ‘an animal, approaching the monitor [lizard] in its mode of dentition, &c., and not yet described,’ while Mosasaurus was defined as ‘The saurus of the Meuse, the Maestricht animal of Cuvier.’ Parkinson reported that Cuvier and others placed this reptile ‘between the Monitors and the Iguanas. But, as is observed by Cuvier, how enormous is its size compared with all known Monitors and Iguanas. None of these has a head larger than five inches; and that of this fossil animal approaches to four feet.’ Suddenly there was a glimpse of the future – the notion of gigantic prehistoric reptiles was began to emerge.23

      The Bucklands had by this time assembled a range of fossils carved out from the Stonesfield strata, including a length of lower jaw with a single tooth,
