No, I am not of the opinion that every thing that dies gets fossilized. Fossilization is a rare event, but even so there are tons upon tons of fossils that have been recovered, and 95% of the total are invertebrates.
The diversity of soft-tissue fossils at Chengjiang is astonishing: alge, medusiforms, sponges, priapulids, annelid-like worms, echinoderms, arthropods (including trilobites), hemichordates, chordates, and the first agnathan fish make up just a small fraction of the total. Numerous problematic forms are known as well, some of which may have represented failed evolutionary attempts at diversity that did not persist for long.
Since many fossils are found on ancient seacoasts, and seacoasts are changing at a rather constant and measurable rate, what effect do you suppose this has on on the availability of fossil finds as we go back billions of years.
I didn't know life went back billions of years. Then again what's a few hundred million years to the availability of fossil finds?
Have you done any math to estimate the effects of subduction on seacoasts? Have you given any consideration to the percentage of seacoasts that have been lost to tectonics?
No. Yes. If the percentage of seacoast that have been lost to techtonics is considerable, the tonnage of fossils recovered is still staggering, and incredibly rich and diverse. What I'm saying is that in all the tonnage of fossils that have been recovered, in the most intact and thorough portions of the extant fossil record, fossils that show any record of the evolution of the complex invertebrates is not there, subduction of seacoasts or not. So if there is evidence of such evolution, it is not to be found in the 95 percent of the extant fossil record that we do have. As the link says, "If their research is valid, at least six major metazoan phyla appeared deep in the Precambrian, hundreds of millions of years before the oldest fossils in the fossil record."
If you are tacitly stating that the fossils are not there (because of subduction of seacoasts) then I will agree with you. Cordially,
Fossils go back billions of years. Fossilization of soft-bodied creatures is rare, and this can be deduced from the lack of fossilized soft-bodied creatures in more recent eras. There are many soft bodied creatures living today, and the conditions for their preservation are unusual.
