Plants take in radiocarbon, along with normal carbon dioxide, during photosynthesis and incorporate it into their tissues.

Some may have mistaken this to mean that the pattern had been dated to twenty,000 radiocarbon years. The shells of stay freshwater clams can, and sometimes do, give anomalous radiocarbon results.
