Lophiodolodus chaparralensis
Diagnosis: The specimen is a heavily worn right lower molar, M1; bunodont; enamel thick; four main cusps, opposite, not oblique in position; main cusps worn off so cusp arrangement is difficult to interpret; triangular in outline; apparently bracyo-lophiodont; wide anterior lingual cingulum; protoconid, though worn off , was evidently the largest cusp on the tooth, possibly it was conical and some what isolated, thoug not as much so as in Phenacodus nor as in Didolodus, thus being more of a lophiodont type.
