Why is this a problem for the evolution scenario? We just say that the
angiosperms evolved. You have to explain not only why angiosperms don't
appear as fossils in the flood deposited sediments but also why none of the
unique, angiosperm chemicals appear in any rock until the angiosperm fossils
appear. There is a chemical called Oleanane which is only produced by
angiosperms. It appears in oils that are sourced from late Cretaceous rocks
one. Older oils have no oleanane! There is no oleanane in Cambrian-Lower
Cretaceous oil. If there were angiosperms in the world prior to the flood,
why did the molecules of angiosperms not end up being buried earlier? Even
today one can find oleanane in the organic matter flowing into the seas via
the rivers. Since presumably there were preflood rivers, why no oleanane?
