Schweitzer herself wonders why these materials are preserved when all the models say they should be degraded.
That is, if they really are over 65 million years old, as the conventional wisdom says. A lone femur bone was excavated in 2004 in Cretaceous clay at 47 6 18N by 104 39 22W in Montana by the O. Miller team in 2005 to retrieve samples for C-14 testing. Collagen: Proteins that are the main component of connective tissue.
It is only useful for once-living things which still contain carbon, like flesh or bone or wood.
Rocks and fossils, consisting only of inorganic minerals, cannot be dated by this scheme.
But, carbon dating can't be used to date either rocks or fossils.Critics charged that the findings were mistaken or that what she called soft tissue was really biofilm produced by bacteria that had entered from outside the bone.Schweitzer answered the challenge by testing with antibodies.Since it would only take less than 50,000 years to reach equilibrium from a world with no C-14 at the start, this always seemed like a good assumption.That is until careful measurements revealed a significant disequalibrium. All the present C-14 would accumulate, at present rates of production and build up, in less than 30,000 years!
