Evidence for the Continental Drift Hypothesis
A gradual decline in the number of dinosaur species would likely mirror an equally
gradual cause of their ultimate extinction. Conversely, a sudden "now you see them,
now you don't" end to the dinosaurs implies a catastrophic cause. Depending on
location and interpretation, the fossil record seems to say different things.
According to some scientists, fossil evidence clearly shows a
decline in the number of dinosaur species for several million years leading up to
the end of the Cretaceous.
The presence of 65- to 70-million-year-old fossilized ocean creatures thousands of
feet above present-day sea level strongly suggests that ocean levels fell dramatically
as the Cretaceous period came to a close.
According to many scientists, continental drift and ocean regression
would have caused continents to become drier, cooler, and less hospitable to dinosaur
life than they had been previously.
