Essay on the Theory of the Earth

by baron Georges Cuvier

The Megalonyx has been very similar to it in its characters, but has been somewhat less; its claws much longer and sharper in the edges. Some bones and entire toes of it have been found in certain caves in Virginia, and in an island on the coast of Georgia[327].

These two enormous edentata have only hitherto presented their remains in America; but Europe possesses one of the same class which does not yield to them in magnitude. It is only known by a single terminal joint of a toe, but this fragment is sufficient to assure us that it was very similar to a pangolin or manis, but to a pangolin of nearly twenty-four feet in length. It lived in the same districts as the elephants, rhinoceroses, and gigantic tapirs; for its bones have been found along with theirs in a sandy deposit in the county of Darmstadt, not far from the Rhine[328].

The osseous brecciæ also contain, but very rarely, bones of carnivora[329], which are much more numerous in caverns, that is to say, in cavities wider and more complicated than the fissures or veins containing osseous brecciæ. The Jura chain in particular, is celebrated for them in the part of it which extends into Germany, where, for ages past, incredible quantities have been removed and destroyed, on account of certain medical virtues which had been attributed to them, and yet there still remains enough to fill the mind with astonishment. The principal part of these remains consists of bones of a very large species of bear (Ursus spelæus), which is characterised by a more prominent forehead than that of any of our living bears[330]. Along with these bones are found those of two other species of bear (U. arctoideus and U. priscus)[331]; those of a hyena (H. fossilis), allied to the spotted hyena of the Cape, but differing from it in the form of its teeth and head[332]; those of two tigers or panthers[333], of a wolf[334], a fox[335], a glutton[336], as well as of weasels, viverræ, and other small carnivora[337].

Here, also, may be observed that singular association of animals, the species resembling which live at the present day in climates so widely separated from each other as the Cape, the country of the spotted hyena, and Lapland, the country of our present gluttons. In like manner we have seen in a cave in France, a rhinoceros and a reindeer by the side of each other.

Bears are of rare occurrence in alluvial strata. Remains of the large species of the caves (U. spelæus), are said, however, to have been found in Austria and Hainaut; and in Tuscany there are bones of a particular species, remarkable for its compressed canine teeth (U. cultridens)[338]. The hyenas are more frequently met with. We have remains of them in France, found along with bones of elephants and rhinoceroses. A cave has lately been discovered in England, which contained prodigious quantities of them, where they were found of every age, and of which the soil presented even their excrements in a sufficient state of preservation to be easily recognised. It would appear that they had long lived there, and that it had been by them that the bones of elephants, rhinoceroses, hippopotami, horses, oxen, deer, and various animals of the class of glires, which are found along with them, and which bear evident marks of their teeth, had been dragged into the cave. But what must have been the soil of England, when these enormous animals lived upon it, and constituted the prey of ferocious beasts! These caves contain also bones of tigers, wolves and foxes; but the remains of bears are of excessively rare occurrence in them[339].

However this may be, we see that, at the epoch of the animal population which we are now passing under review, the class of carnivora was numerous and powerful. It reckoned three bears with round canine teeth, one with compressed canini, a large tiger or lion, another feline animal, of the size of the panther, a hyena, a wolf, a fox, a glutton, a martin or pole-cat, and a weasel.

The class of glires, composed in general of weak and small species, has been little observed by the collectors of fossil remains; and, in all cases, where the bones of these animals have been found in the strata or deposits of which we speak, they also have presented unknown species. Such, in particular, is a species of Lagomys found in the osseous brecciæ of Corsica and Sardinia, somewhat resembling the Lagomys alpinus of the high mountains of Siberia: so true is it that it is not always in the torrid zone only, that we are to seek for the animals which resemble those of this period.

These are the principal animals, the remains of which have been found in that mass of earth, sand, and mud,—that Diluvium, which everywhere covers our large plains, fills our caverns, and chokes up the fissures in many of our rocks. They incontestibly formed the population of the continents, at the epoch of the great catastrophe which has destroyed their races, and which has prepared the soil, on which the animals of the present day subsist.

Whatever resemblance certain of these species bear to those of our days, it cannot be disputed that the general mass of this population had a very different character, and that the greater part of the races which composed it have been utterly destroyed.

What astonishes us is, that, among all these mammifera, the greater number of which have their congeners at the present day in the warm parts of the globe, there has not been a single quadrumanous animal,—that there has not been collected a single bone or a single tooth of an ape or monkey, not so much even as a bone or a tooth belonging to an extinct species of these animals.
