If I understand correctly we can’t do it to anything new because the ratios in the atmosphere got messed up after nuclear weapon testing in the 1950s. Anything breathing after that time can’t be properly compared with this technique. Maybe that will change though.
If my bones survive for 500 years will it be enough?
