As I understand it, the earliest evidence for hair in _Synapsida_ is
supposed whisker pits in basal _Cynodontia_. This doesn't mean that hair
evolved from sensory bristles -- it could easily be the other way around,
since senory bristles are one of the few types of hair that leave skeletal
indicators. Someone correct me if I'm wrong here.
