Description
Original diagnose after Case (1978) p. 190 [388]: Teeth of average size, larger than Odontaspis hardingi CAPPETTA & CASE (1975b), which it closely resembles. The main difference between O. sanguinei n. sp. and O. hardingi is in the structure of the lateral cusplets on either side of the central cusp of the tooth
