I had never heard of these fossils, and it is my current understanding that they represent a wide diversity of invertebrates that sprang forth in the Cambrian period. Schroeder claims that according to theories of natural selection and random mutation, such a diversity could not have arisen in such a brief time period without a little design. Many years ago, the puzzle from the Cambrian Explosion did make me think. However, it seems to me that before you can have fossils, you must first have fossil-making processes. My surmisal is that a lot of the limestone which preserved the fossils was precipitated through the buildup of discarded animal shells. If so, the fossil record would not have begun to accumulate under the build-up until after a significant abundance of shell-producing animals had developed, died, and made their contribution to the fossil record and the fossilizing processes. Does anyone know about the mechanisms of fossilization in a marine environment? Does fossilization occur as part of a continuous accumulation of organisms and calcium deposits, or is it periodid and erratic?
