I wonder what happens in adults that have reached their final adult size (and thus have a growth rate close to zero. Using the same logic and the same equation that Gillooly et al. use to “calculate” temperature during ontogeny, I calculate that the body temperature of an adult Apatosaurus is close to zero [Kelvin].
T = 10 log [G (M exp -0.75)/g0]
If G is 0, we get T = 10 log 0 = 10 x 1 = 10. Right? Ten kelvin! WooHoo!!!
