Bunophorus sinclairi

Osteichthyes - Diacodexeidae

Taxonomy
Bunophorus sinclairi was named by Guthrie (1966). Its type specimen is PU 13448, a mandible (right ramus with P4 and M2-3, and a left ramus with P4 and M1-2), and it is not a trace fossil. Its type locality is Davis Ranch, which is in a Bridgerian fluvial-lacustrine mudstone in the Wind River Formation of Wyoming.

It was synonymized subjectively with Bunophorus etsagicus by Guthrie (1971).

Diagnosis
ReferenceDiagnosis
R. K. Stucky and L. Krishtalka 1990iffers from all other species of Bunophorus in having (1) an in- cipient to definite metconid on P4, (2) a pericone (often), large hypocone and isolated metaconule on M1- 2, (3) a weak, incomplete cristid obliqua on M2_3, and (4) an expanded, bulbous entoconid and low, bulbous, subequal molar trigonid and talonid on M1_3 • Also, P4/4 more gracile (less inflated, less bulbous anteriorly) than in B. etsagicus and relatively much more gracile than in B. macropternus; M1_3 paraconid vestigial to absent, unlike B. robustus, B. grangeri, B. pattersoni; P4 lacks paraconid, unlike B. robustus and some B. grangeri; larger than B. ro- bustus, B. macropternus, B. pattersoni.
