R. K. Stucky and L. Krishtalka 1990 | Distinguished from all species of Bunophorus by hyperinflation of P4/4 (in proportion to Ml/1) and lingual area ofM1-3; strong cingulid on M3• Additionally: unlike B. robustus, B. grangeri and B. pattersoni (most), P4 paraconid absent, M1_3 paraconid vestigial or absent; differs from B. sinclairi in lacking a metaconid on P4 and pericone, hypocone and isolated metaconule on M1- 2 , and retaining a complete, distinct cristid obliqua on M1_3 • |
