Description
Original diagnose after Case (1981) p. 55 [391]: Anterior tooth : of a juvenile, crown height approximately 1.5 mm, and width of the tooth across the three cusps approximately 1.5 mm, a partially fragmented tooth, missing portions of the root base, enameloid tooth surface is complete, although it is smooth-devoid of any plication or rugosity. Median-lateral tooth : of an adult, approximately 5 mm in its longest width, and approximately 2 mm in its greatest height (from the base of the root to the tip of the crown apex), and in its occlusal aspect, the median-lateral tooth of Heterodontus pineti n. sp., shows an overall "conchoidal" ornamentation on its enameloid surface (pi. 1, fig. 2d), root base slightly less than the length of the crown, and noticeable foramina and fenestration present.
