"Northeast Siberia, which was not covered by ice in the last Ice Age, conceals another enigma. The climate there had apparantly changed drastically since the end of the Ice Age, and the yearly temperature has dropped many degrees below it's previous level. Animals once lived in this region that do not live there now, and plants grew there that are unable to grow there now. This change must have occurred quite suddenly. The cause of this Klimasturz has not been explained. In this catastrophic change of climate and under mysterious circumstances, all of the mammoths of Siberia perished."
"The mammoth belonged to the family of elephants. Its tusks were sometimes as much as ten feet long. Its teeth were highly developed and their "density" was greater than in any other stage in the evolution of the elephants: apparently they did not succumb in the struggle for survival as an unfit product of evolution. The extinction of the mammoth is thought to have coincided with the end of the last glacial period."
"Tusks of mammoths have been found in large numbers in northeast Siberia; this well-preserved ivory has been an object of export to China and Europe ever since the Russian conquest of Siberia and was exploited in even earlier times. In modern times the ivory market of the world still found its main source of supply in the tundras of northeast Siberia."
"In 1799 the frozen bodies of mammoths were found in these tundras. The corpses were well preserved, and the sledge dogs ate the flesh unharmed. "The flesh is fibrous and marbled with fat" and "looks as fresh as well frozen beef." " (footnoted- D.F. Hertz in B. Digby, The Mammoth, 1926 p.9)
"What was the cause of their death and the extinction of their race? Cuvier wrote of the extinction of the mammoths: "Repeated irruptions and retreats of the sea have neither all been slow nor gradual; on the contrary, most of the catastrophes which have occasioned them have been sudden...If they had not been frozen as soon as killed, they would have been decomposed by putrefaction..." "
"....Darwin admitted that he was unable to find an explanation for the extermination of the mammoth, an animal better developed than the elephant which survived.(footnote) But in conformity with the theory of evolution, his followers supposed that the gradual sinking of the land forced the mammoths to the hills, where they found themselves isolated by marshes. However, if geological processes are slow, the mammoths would not have been trapped on the isolated hills. Besides, this theory cannot be true because the animals did not die of starvation. In their stomachs and between their teeth undigested grass and leaves were found. This, too, proves that they died from a sudden cause. Further investigations showed that the leaves and twigs found in their stomachs do not grow in the regions where the animals died, but far to the south, a thousand or more miles away. It is apparent that the climate has changed radically since the death of the mammoths; and as bodies of the animals were found not decomposed but well preserved in blocks of ice, the change in temperature must have followed their death very closely or even caused it."
"There remains to be added that after storms in the Arctic, tusks of mammoths are washed up on the shores of the arctic islands; this proves that a part of the land where the mammoths lived and were drowned is covered by the Arctic Ocean.".....
