Diagnosis
ReferenceDiagnosis
R. K. Stucky and L. Krishtalka 1990Differs from B. robustus, B. grangeri and B. pattersoni in having a vestigial to absent M1_3 paraconid, and in lacking a paraconid on P4; unlike B. macropternus, P4 not as hyperinflated in proportion to and M3 without labial cingulid; unlike B. sinclairi and B. pattersoni, P4 more inflated (and anteriorly bulbous) in proportion to M1; unlike B. sinclairi, P4 lacking metaconid, M1_3 with stronger, uninterrupted cristid obliqua, and P c M 3 less bunodont, with trigonid higher than talonid; larger than B. robustus, B. macropternus and B. pattersoni.
