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

For object over 4,000 years old the method becomes very unreliable for the following reason: Objects older then 4,000 years run into a problem in that there are few if any known artifacts to be used as the standard.

Libby, the discoverer of the C14 dating method, was very disappointed with this problem.

He understood that archaeological artifacts were readily available.

So when you hear of a date of 30,000 years for a carbon date we believe it to be early after creation and only about 7,000 years old.

Shell may succumb to isotopic exchange if it interacts with carbon from percolating ground acids or recrystallization when shell aragonite transforms to calcite and involves the exchange of modern calcite.

The surrounding environment can also influence radiocarbon ages.

by Helen Fryman Question: What about radiocarbon dating? Response: I asked several people who know about this field. (1.) C14 dating is very accurate for wood used up to about 4,000 years ago.

This is only because it is well calibrated with objects of known age.
