"Over time, every living thing on the planet has absorbed this extra Carbon-14 which still persists." Is that as consistent in absorption? More so animals that feed upon different levels and maybe more so - do plankton absorb more or less and any animal feeding upon them would see a higher rate perhaps. I'm still looking into these aspects - fun google time. #1 Another train of thought I have from reading this is: We may well read in the future about plastic pollution being used to measure metrics in life forms. [EDIT ADD] #1 https://en.wikipedia.org/wiki/Carbon-14 https://en.wikipedia.org/wiki/Carbon-14 It is naturally formed by cosmic rays, it has also been measured as highers in area's that atomic testing happened (so near Australia) and with that, Southern hemisphere. Given that, one would expect, any life form that was located near area's near the poles or southern oceans would be more exposed to the natural and atomic unnatural sources and whilst the unnatural sources would dissipate - anything exposed during the early times would also have higher levels than such a lifeform in those same area's today due to decay and dispersion.

I think you can assume they didn't change the diet too much, so before 1945, measuring the carbon in the bones(?) you should get a nice smooth exponential curve, and then a jump in 1945 [Is there a small delay?].

  Whilst their food would not of changed in source, the content would of had spikes above global average it periods of time due to the atomic spike, also how that dispersed and how long until equilibrium would all be factors that come into play. Let alone natural hotspots from solar radiation increase near the poles. But then the error +/- rate would seem to accommodate those kind of margins, but always nice if there is a way of narrowing those margins, so may be a field of research that has some headroom and also help learn many other tangents and maybe another data point for historical solar radiation.
