DOI: 10.1002/bies.202100060
Abstract: We suggest that mammalian endothermy was established amongst Middle Jurassic crown mammals, through reviewing state‐of‐the‐art fossil and living mammal studies. This is considerably later than the prevailing paradigm, and has important ramifications for the causes,… read more here.
