The earliest reliable record of hair is found in a fossil of the Paleocene period, in which the structure of hair cuticles is preserved. Its appearance suggests that the complicated structure of the hair follicle, closely similar to that of present-day mammals, had already appeared at this time.[well established][VHOG]
Development notes:Formation largely takes place during fetal and perinatal skin development. However, after skin wounding de novo hair follicle formation may also occur in adult mouse and rabbit skin[DOI:10.1016/j.cub.2008.12.005].
