The Flood, fossils, & the geologic evidence

Perhaps, but I think the smart money is on axial tilt. And signatures of seasons are documented well past 500,000 years ago in a good selection of ice cores. And there's no signature of seawater in those ice cores whatsoever - one would think a global flood might leave one.

Including, slevesque, the ones that Mary Schweitzer and group found the flexible remains of blood vessels in. See Soft tissue and cellular preservation in vertebrate skeletal elements from the Cretaceous to the present | Proceedings of the Royal Society B: Biological SciencesSchweitzer calls it "bone" pretty much throughout, but she points out that the collagen is gone and the hard parts are "crystalline" - indicating that they aren't fibrous hydroxyapatite any more.

And the problem with that is what, exactly? We can measure how fast the Himalayas or the California Coast Ranges are growing. We can measure how long rocks on those have been exposed to the sky, and how old the insides of some of them are. All the results point to millions of years. What has Oard measured?
