Short summary
This project describes mammal faunal response in the zone of the ETM2 and H2 hyperthermals (rapid global warming events) of the early Paleogene in the south-central Bighorn Basin, WY. The response includes changes in faunal structure and species relative body size. Comparative analysis suggests that environmental moisture and rate of change are important moderators of response.
