2013 and runs to some 1,000 pages. It tells a curious story and is excellent bedtime reading, although, as we know, no book on the future of our climate is destined to have a happy ending.

Philosophers took a long time to accept that the world had once been a different place. The next step up our ladder of understanding was the dawning realization that huge monsters had once lived on our Earth – creatures whose remains we could find, yet whose nature we could not yet discern. It was the insight of a young French naturalist that introduced the revolutionary idea that there had once been gigantic life forms that had long since ceased to exist. This great step was the brainchild of Jean Léopold Nicolas Frédéric Cuvier. Cuvier – known ever since as Georges – became the greatest naturalist of his age in France, and arguably in Europe. He was born in 1769 in the ancient town of Montbéliard, nestling close to the border with Switzerland, which at the time was ruled by Germany. His father, Jean Georges Cuvier, served in the Swiss Guards, and his mother, Anne Clémence Chatel, was devoted to him and spent much time teaching him. By the time he went to school he showed a fearsome eidetic memory and could recite in detail the chronology of kings and queens, princes and emperors. An enduring fascination for unravelling the past drove his lifetime of study. As a boy, working with his mother, the young Cuvier pored over the antiquated works on natural history by the great French naturalist Georges-Louis Leclerc, Comte de Buffon, and also those by Conrad von Geßner, the influential Swiss zoologist. As a result, by the age of 10 Cuvier was fully conversant with zoology and the classification of all the main animal types.1
Throughout his twenties, Cuvier became increasingly interested in fossils. In 1796 – aged just 27 – he was elected a member of the Academy of Sciences in Paris and presented his first paper on the comparisons between Asiatic and African elephants, and the fossilized remains of mammoths. He listed the differences between African and Asiatic elephants and clearly showed that they were distinct species. Cuvier carefully concluded that the fossils must represent creatures that were extinct. Some of the fossils he studied were of the animal still known as the ‘Ohio Animal’ – the monstrous bones were first excavated in the U.S. in 1739 and were always thought to be the remains of elephants. Cuvier demonstrated that they were anatomically distinct, and he subsequently proposed the name ‘mastodon’. Later that year he spoke of a huge skeleton that had been excavated in Paraguay. He compared its skull with the appearance of present-day sloths, and concluded that this was another kind of gigantic ground-dwelling sloth. He decided to name it Megatherium. These were two crucial papers – first, they demonstrated the value of comparative anatomy, and they also established the view that there were huge forms of life which no longer existed. The young Cuvier ensured that the idea of extinct giants was formally established, and his two lectures set the science of palæontology onto a firm footing.
In 1784 an Italian philosopher, Cosimo Alessandro Collini, reported on a curious fossil that had been dug out of the smooth, creamy Solnhofen limestone in Bavaria. The fossil was part of the cabinet of curiosities in the palace of Charles Theodore, Elector of Bavaria at Mannheim, and it had perfectly preserved wings. Collini concluded that these were the remains of a sea creature with huge fins, though a French/German naturalist named Johann Herman insisted that the fossil represented some kind of bat. Collini heard of Cuvier’s growing interest in fossils, and wrote to him about it, and by 1801 Cuvier had concluded that the fossil represented a flying reptile. He gave it a name we recognize today: ptero-dactyle. Other investigators continued to debate its true nature; it was sometimes claimed to be a bird, a catfish, or a lizard. Not until the 1860s was the nature of a pterodactyl – as a winged reptile – generally agreed.2
It was also Cuvier who recognized the true nature of Johann Scheuchzer’s fossilized skeleton; in 1812 he correctly identified it as a fossil salamander. Until that time the petrified remains had been accepted by every scholar as evidence of a drowned man from the biblical flood, and it fell to the French philosopher’s genius to reveal the truth. The specimen had been purchased by the Teylers Museum in Haarlem, the Netherlands, in 1802 and it remains there on display to this day. It was formally named Salamandra scheuchzeri by a German botanist, Friedrich Holl, in 1831.
Cuvier’s work was widely disseminated and in 1799 it came to the attention of a physics professor in the Netherlands, Dutch scientist Adriaan Gilles Camper. He had been contacted by both Hoffmann and Drouin about the ‘monster of Maastricht’ to resolve whether it truly was a fish, a crocodile or a sperm whale. The fossil had remained a mystery and in England it had become a topic of fascination for James Parkinson, a young and enthusiastic physician with a passion for geology. Parkinson didn’t enjoy trudging over rocks and was no great enthusiast for fieldwork. He obtained most of his specimens from the London dealers and eventually amassed a collection of over 3,000. Parkinson became Britain’s leading palæontologist.
Meanwhile, an enthusiastic student of rocky strata was a young resident of southern England who spent much of his time collecting in the field. This bright young man was Gideon Algernon Mantell, born in Lewes, Sussex, on February 3, 1790, an enthusiastic youngster destined to study medicine and eventually to become a leading obstetrician. Although medicine was to be his profession, his enduring passion was the study of fossils. During Mantell’s childhood, words like geology, scientist and palæontology were largely unknown. There was, however, nothing new about the term fossil. It derives from the Latin fossilis, the past participle of the verb fodere, ‘to dig’, and once meant anything excavated from the ground. It acquired its modern-day meaning in the 1730s, some 70 years after Robert Hooke was writing about fossils in his book Micrographia.
The young Mantell was keen to meet the great James Parkinson, but the enthusiasm was not reciprocated for several years. This was frustrating for a budding enthusiast, for there were few scientific publications that one could study. Parkinson was persuaded that it was time to publish a formal account, and he compiled three majestic folio volumes entitled Organic Remains of a Former World, each extensively illustrated. They were published in London in 1804, 1808 and 1811 – the last being the same year in which Gideon Mantell graduated from St Bart’s Hospital in London. In later life, the elderly Parkinson was more inclined to meet Mantell, and eventually they became firm friends. Parkinson wrote:
I am totally ignorant of the science [of fossils] which teaches us their natural history … I find myself so totally ignorant of their origin, as not even to know in what class of nature’s works to place them.3
This was an honest reflection of the degree of understanding at the time, and his three volumes represent an impressive collation of what was then known. There are separate sections dealing with fossilized shells and familiar marine creatures, of course; and he went on to describe fossils of what he concluded were whales, crocodiles, elephants, mastodons, and even several rhinoceroses. Petrus Camper, the Dutch physicist, had by this time speculated that perhaps a fossil he had found was the skull of a giant monitor lizard, and in 1808 Cuvier agreed. Cuvier published an engraving of what he called ‘the large fossil animal of the quarries of Maastricht’ and he decided to name it Mosasaurus, after the River Meuse, near where it was found.4
Parkinson later reproduced the illustration as Plate XIX Fig. 1 in his own book. The original specimen taken back to Paris by Napoleon’s troops is still on display at the Muséum National d’Histoire Naturelle in the Jardin des Plantes, though the Netherlands authorities have recently been demanding its return.
Nobody dwelled on the significance of these early finds; the fossilized remains of seashells continued to be taken by everybody as proof of the biblical story of the flood. Similarly, when three-toed dinosaur footprints were
