A newly discovered fossil has revealed the evolutionary adaptations of a 165 million-year-old proto-mammal, providing evidence that traits such as hair and fur originated well before the rise of the first true mammals. The biological features of this ancient mammalian relative, named Megaconus mammaliaformis, are described by scientists at the University of Chicago in the Aug. 8 issue of Nature.
