It is worth noting that the analysis cannot at present resolve endotherms
vs. ectotherms. It is just a thermometer: it is not a thermometer with a
time component.

Too many people in the press about this seem to think that warm-blooded
animals actually have higher body temperatures than cold-blooded ones.
There is a good research protocol to try and test this (basically
following Barrick et al.'s and Fricke et al.s work back in the 1990s), but
it hasn't been done yet.
