This brings to light another interesting anomaly, not related to the
Baumgartner model, but to the whole question of non-uniformity in the
fossil record. As Glenn has just pointed out indirectly, 95% of the
sediments on the ocean floor
today are Mio-Pliocene. This leaves 5% for the Oligocene, Eocene,
Paleocene, Cretaceous and Jurassic. I will be interested in whatever
explanations any of you may have for this, because when I originally heard
the report at GSA, there was a deafening silence from the captivated
audience when the author asked for explanations, and he had none to offer
himself. Looks to me like massive continental runoff characterized the
Mio-Pliocene worldwide. That is something Baumgartner and others should
not ignore in their modeling.
