A fast and accurate method of measuring angles of features of microscopic fossil teeth [using stereoscopic camera lucida and contact goniometer] is offered which in no way endangers fragile specimens. It is hoped that this will allow angles in degrees to replace vague statements such as; 'The apex is more attenuate than that of . . .' or 'The re-entrant folds are more open in . . ..' It is also suggested that the accurate measurement of occlusally related angles of upper and lower mammalian dentitions will be another major consideration in associating isolated upper and lower teeth.
