And the flood was forty days upon the earth; and the waters increased, and bare up the ark, and it was lift up above the earth. Genesis 7:17
"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." ICR
