Contrary to our expectations, extinction selectivity based on
total calorific needs, which emphasises body size, did not differ between hyperthermals and other time intervals [images lightly adapted from Gavirneni et al. 2025, linked above]

Together, this may suggest an evolutionary trend checking heterotroph mass-specific energy and/or oxygen use, with an important role for tropical heat and rapid warming events

Extinction selectivity against a high mass-specific metabolic rate was especially strong in the paleotropics during hyperthermal events

Whole body metabolic rate increased through time, consistent with increasing maximum body sizes and the postulated ramping up of ecosystem energetics. Mass-specific metabolic rate, the energy used per g tissue, however, decreased...
