Mammoths
Because of their prized ivory tusks, much is known about preserved mammoths in the Arctic. Convoys would return each year from one island in particular with mammoth tusks, each weighing 150-200 pounds. In 1809, 10,000 pounds of fossil ivory were taken.[18]
From about the 1300's onwards, this area supplied the ivory demands of China, and from the 1700's on, also met European demand.. In the last decades of the 19th century, 20,000 pairs of tusks in perfect condition were exported for the ivory trade.[18]
According to a recent estimate, there may be around 3 million mammoths still buried in Siberia.[18]

Woolly Mommoths: Surprises In the Snow!
As it thawed, the flesh of a frozen mammoth found near the mouth of the Lena River in 1799 was eaten by dogs, polar bears, wolves, wolverines, and foxes. Georges Cuvier (1769-1832) wondered what natural process today rapidly buries and then freezes large animals so quickly that their thawed flesh is edible? If they freeze slowly, Cuvier wrote, they would putrefy to the extent that their flesh would be entirely inedible.[18]
The megacatastrophe (Noah's Flood?) that befell the mammoths involved a sudden and intense widespread rush of water (Sea shells were found with some mammoths.[18]) that not only killed the animals but also buried them along with trees and other vegetation under continuous beds of loam and gravel. Immediately afterwards the land became frozen by a sudden and permanent climate change.[51]
Late in the nineteenth century, Sir Henry Howorth wrote Darwin, asking him to explain the mammoths' demise. Darwin replied that for him it was an insoluble problem. That is, it was "insoluble" for the theory Darwin was proposing.[18]
