Megafaunal split ends: microscopical characterisation of hair structure and function in extinct woolly mammoth and woolly rhino
The large extinct megafaunal species of the Late Pleistocene, Mammuthus primigenius (woolly mammoth) and Coelodonta antiquitatis (woolly rhino) are renowned for their pelage. Despite this, very little research has been conducted on the form and function of hair from these iconic species. Using perma...
