"The five rules of global Flood paleontology explain the fossil evidence of the rock record and also fit closely with the overall succession of global megasequence deposition by the Flood.
These rules are
1) Sudden appearance: creature kinds appear suddenly in the rock
record with no evidence of evolutionary ancestors;
2) Stasis: fossil creatures look similar to living counterparts as well as fossil counterparts buried later, with no evidence of evolution;
3) Marine mixing: land creatures are often found mixed and buried together with marine creatures;
4) Burial by ecological zonation: as the floodwaters steadily progressed from the oceans onto land, there’s a corresponding representation of ecosystem burial; and
5) Recent burial around 4,500 years ago: soft tissue and biomolecules are found in fossils in all Flood strata."
