What in the world are you bringing up carbon isotopes for?

Quoted from: Chronological Methods 8: Radiocarbon Dating A University of California in Santa Barbara course.
Thus, when he writes, in Note 9. "The radiocarbon (14C) dating method, although demonstrating that the fossil wood samples cannot be millions of years old......" he is quite wrong. The method demonstrated only that the organic carbon cannot be millions of years old. The stone and fossils are still millions of years old, but the organic carbon is clearly contamination from the "oxidised silty top" that he mentioned as being the fossil's environment. This is 'in situ' contamination, a source of problems well known to those working in the field, but that somehow escaped Dr. Snelling's consideration. Maybe he should have taken the course.
