and if it's determined to be the print of someone born feb. 29th ... it's only 5 million years old.

I think I’ve seen this guy before on CNN. Or was it perhaps MSNBC?

Scientists are using carbon tests on plants found in the rock to determine its exact age, Hawass said. Hawass knows better. This gives geology a bad name.
Or journalists. I would prefer to think that the journalist was completely confused about the different radiometric dating methods.

I think they were talking about organic material in the mud, but I don’t think radiocarbon dating goes much further back than 60,000 or 70,000 years. Wikipedia seems to support those dates. Coyoteman is the expert however. Two million years???? The normal upper limit for most labs and most equipment is in the 50,000 year range, with some experimental AMS work extending toward the 80,000 year range.
I am not sure what radiometric test they would use on old mud; most of the test used in fossil studies in Africa I believe are applied to volcanic layers above and below the fossil-bearing layers.
