The Earth's Shifting Crust by Charles Hapgood - wire of information

THE GREAT EXTINCTIONS 271
are today (141:217). Kulp found, by radiocarbon dating, that
deposition of sediments along the eastern coast of North
America occurred at a fast rate prior to about 15,000 years
ago (262). Millis cited evidence of very violent winds during
the melting phase of the Wisconsin icecap (308:14). Violent
storms would seem a very natural explanation for the peculiar
finds of many bodies of animals crammed into caverns
and fissures, dating from various geological periods, that
have been found in various parts of the world. Hibben men-
tions one of these (212:173-74). It would seem possible that,
in storms of the character that may have occurred, caverns
may have been the only refuges available for man and beast
alike. Dodson refers to the fact that the destruction of ani-
mals in dust storms was apparently the cause of the preservation
of many fossils (115:77). Volchok and Kulp, in their ex-
amination of ionium dating as applied to several Atlantic
Ocean deep-sea cores, remarked that "at the close of the Wis-
consin [glacial period] the rates of sedimentation for both
sediment types [red clay and Globigerina ooze] increased by
factors of 2-4" (442a:2ig). This means that the rate of dep-
osition of sediment in the deep sea at these points was in-
creased by from 200 to 400 per cent. This certainly suggests
an unusual turbulence for the climate.
It is little wonder that, faced by all these unpleasant con-
ditions, a good many species in all parts of the world, even
very far from the icecaps, gave up the struggle for existence.
In conclusion, it appears to me that the whole mass of the
evidence relative to the animal and plant remains in the
Siberian tundra, interpreted in the light of the evidence
from North America, sufficiently confirms the conclusion
that there was a northward displacement of Siberia coincident
with the southward displacement of North America
