Dates up to this point in history are well documented for C14 calibration.

Archaeologists vehemently disagree over the effects changing climate and competition from recently arriving humans had on the Neanderthals' demise. Because we have measured the rate at which the sand grains fall the radiocarbon decay ratewe can then calculate how long it took those carbon atoms to decay, which is how long ago the mammoth died.

Since all pre-Flood plants would have had the same low radiocarbon levels when they were buried, and they all formed into coal beds during that single Flood year, then those coal beds should all have the same low radiocarbon content. If it is low, production rises. This article is reproduced with permission from the magazine Nature.
