1888 H. F. Osborn in Amer. Naturalist 22 972 (table) Terms proposed... Protoconule... Terms now in use... Anterior-intermediate cusp.

1905 Amer. Geologist 35 244 The intermediate cusps (protoconule and metaconule) are both well-defined.

1933 A. S. Romer Vertebr. Paleontol. xii. 248 Between protocone and paracone there is often a smaller cusp, the protoconule.

1968 R. Zangerl tr. B. Peyer Compar. Odontol. 187 Intermediate cusps occurred along the trigon, a protoconule between protocone and paracone and a metaconule between protocone and metacone.

1996 Jrnl. Mammalogy 77 75/1 In Hylopetes, protoconules are absent, but there is usually a narrow isthmus on the protoloph close to the protocone.
