Bunophorus etsagicus
Taxonomy
Mioclaenus etsagicus was named by Cope (1882). Its type specimen is AMNH 4698, a set of teeth (LP3-M3, RP3-M3), and it is a 3D body fossil.
It was recombined as Pantolestes etsagicus by Cope (1883); it was recombined as Systemodon etsagicus by Cope (1884) and Granger (1908); it was recombined as Trigonolestes etsagicus by Roger (1896), Matthew (1899) and Hay (1902); it was recombined as Eohyus etsagicus by Wortman (1898); it was recombined as Eohippus etsagicus by Granger (1908), Hay (1930) and Stirton (1940); it was recombined as Helohyus etsagicus by Matthew (1909); it was recombined as Hyracotherium etsagicus by Denison (1937); it was synonymized subjectively with Hyracotherium angustidens by Kitts (1956); it was recombined as Bunophorus etsagicus by Sinclair (1914), Gazin (1962), Guthrie (1967), Gingerich (1980), Stucky and Krishtalka (1990), Stucky (1998) and Theodor et al. (2007).

Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| R. K. Stucky and L. Krishtalka 1990 | Differs 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. |
