Description
Original diagnose after Case (1978) p. 180 [388]: Teeth of medium to large size, ranging in their root width from O i a n to 2 a n , and averaging 1.5 cm. Tooth crown is partially plicated at the enameloid border (as in Synechodus), and the plications follow the tooth contour up from the enameloid border approximately 1 the distance of the tooth height, towards the apex of the crown.
