Description
Original diagnose after Chapman (1913) p. 143 [442]: Description of Carcharoides tenuidens, sp. nov.
Holotype. — Tooth of slender habit. Root slightly arched and moderately stout. Crown acutely triangular, flattened on the outer face near the junction with the root, and otherwise depressed convex ; inner face roundly convex ; edge view showing a wide recurvation of the lateral line, as in Odontaspis. Edge crenulate, with blunt serrae. Lateral denticles well developed, sharp, and turned towards the crown.
Measurements. — Total length from base size. to apex, 20.25 rnm. Extreme width at base of root, 12 mm.; thickness, 4.5 mm. Width of crown at junction with root, 7.25 mm. ; thickness, 3.75 mm. Length of lateral denticle, 3.75 mm.
Occurrence. — Waurn Ponds quarry, near Geelong. Cainozoic (Janjukian) age. This specimen was found by Mr. J. F. Mulder, to whom the credit is due of discovering many interesting and rare fossils in the Geelong area.
