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]
