It(fossilization) ordinarily is a chemical process that takes years of action by silica-bearing water or perhaps other mineral values percolating through the soil with relatively little oxygen, perhaps water whose oxygen content has been consumed by other organic debris in the soil. . . . I don't think we have even developed laboratory methods that could do this inside a year.
I agree with your paragraph about how fast fossilization occurs on an individual fossil. Taken by itself, my statement does not mean what I was trying to say. Rather, I was trying to dispute the notion that fossils would occur at a steady rate over the eons.
I spent some time examining some geological contact lines between fossilized strata and unfossilized strata. It seemed in my specific sites that it was a very sharp line of demarcation. Rates of deposition of carbonate rock vary from place to place. In some sites it can be two or three feet in one year, but the general rate is likely a few hundred feet in anything from ten million to a hundred million years. But what has not been reported is a transitional layer where a few fossils are present grading into something with much more, except in places where the conditions for fossilization were marginal and then improved. . . ..
Exactly. Rivers change course, populations change habitat, etc. There is no reason to expect a smooth fossil transition.
the sense I get from what I have read or seen would lend more credence to the argumentative position that life came on very rapidly. . . . stabilized for millions to hundreds of millions of years, and then made remarkably sudden changes. . . .over and over again. Probably due to sudden changes in gross chemical mass equations or sensational climate changes. . . .
Life "came on" about 3.5 billion years ago, over the course of about .5 billion years. I don't see that as "rapidly". However, seeing fossils stabilize and then change suddenly sounds like what we should expect when a planet has periods of stability followed by periods of sudden change.
