The conventional methods by which these alleged dates are assigned to these types of discoveries are untrustworthy because they are based on three basic assumptions that cannot be confirmed. The assumptions upon which they are based are:
1. Constant rate of decay.
2. No presence of daughter product alongside parent product.
(What is meant by parent and daughter product is one element produced from another. For example, C-14 from C-12 or Lead from Uranium. C-12 is a parent product and C-14 is the daughter product of C-12. Uranium is a parent product and lead is the daughter product of Uranium)
3. Closed system which is based on the assumption that the sample being dated was not contaminated by any external elements.
With organic material, which would include this wolf’s head, the rate of decay can slow or accelerate under certain conditions which makes C-14 dating under which this wolf’s head would have undergone unreliable.
Because the wolf’s head that was discovered was found under conditions that have kept it fairly intact and preserved, the rate of decay would have been very slow in comparison to other conditions which would have accelerated the rate of decay.
All that C-14 dating can really tell anyone for is the ratio of C-12 to C-14, but it can never really tell you how old something is because, again, the assumptions upon which the entire dating premise is founded cannot be confirmed. The same goes for radiometric dating as well.
