_More than half of these sixteen mammals seem to have died out between 10,000 and 8,000 years ago, when the last glaciers were retreating and early man hunted with Sandia and fluted points. These latest acceptable dates of survival in North America are drawn from Jim Hester’s “Late Pleistocene Extinction and Radiocarbon Dating,” in American Antiquity for July, 1960. The dates vary in precision from 150 to ± 500. There may come later finds._] If the Quito mastodon and pots were indeed neighbors in time, then they provide the only evidence—ex post facto, at that—for the remarkable statement of the geologist William B. Scott in 1913: “Many Pleistocene mammals were in existence only a few centuries ago, in what is called ‘historic time’ in the Old World. Several skeletons of the American Mastodon have been found in bogs, covered by only a few inches of peat, with more or less of the hair and recognizable contents of the stomach preserved.”[12] Eiseley has questioned the evidence that the mastodon had hair, and he has pointed out that a peat bog is an ideal place for the preservation of vegetable matter such as that animal lived upon.[13] The bogs and their fossils lie to the south of the Great Lakes, which formed as the ice fields began to retreat into Canada. Since the retreat began between 10,000 and 12,000 years ago, it is obvious that bogs could have formed and mastodons been trapped in them far longer ago than a few centuries—whether “few” means five, ten, or even fifteen. A hundred years ago Charles Lyell commented on the profusion of mastodon bones in North American bogs compared with the paucity of such fossils in the bogs of Europe; and argued for the late survival of these animals in the New World.[14] Answering him, Eiseley points out first of all that for many centuries such skeletons were hunted out and salvaged by Europeans in search of ivory or the materia medica of the unicorn’s horn. Further, the mastodon, which was a forest lover and fell a natural victim to bogs, was almost unknown to Europe, while the mammoth kept mainly to dry, open steppes. We know that bogs both in our Great Lakes area and in northern Europe were postglacial, “and that is all. There exists no evidence, at present, which seems to demand in the New World a lingering extinction of the American elephants in a way much different from the course of events in Europe.”[15] Sloth and Camel in Dry Caves
