There are some interesting facts on the geological column, of the fossils 95 % of them are marine invertebrates, mainly shellfish. Of the remaining 5%, 95% are algae and plant fossils. 95% of the remaining 0.25% includes other invertebrates including insects. The remaining 0.0125% includes all vertebrates, mostly fish. 95% of the few land vertebrates consist of less than one bone. I got these figures from “The Young Earth” (Morris, J .D., 1994). The fossil record doesn’t look like the ones we see in college textbooks with equal space for all the different types of animals. The fossil record seems to point to a marine cataclysmic event and not long ages.
