Pucanodus gagnieri Muizon & Marshall 1991
Description
Pucanodus gagnieri Muizon & Marshall, 1991
DIAGNOSIS. — See Muizon & Cifelli (2000).
DESCRIPTION
A mandible fragment bearing m2-3 (MHNC 13869) has been referred to Pucanodus gagnieri (Fig. 11) because it presents the mesiodistal compression of the molars especially m3, which is characteristic of that species (Muizon & Marshall 1991). The specimen is approximately of the size of a small Tiuclaenus. The teeth are almost unworn and better illustrate this taxon than the holotype (a mandible with p3-m3), the teeth of which, are notably worn. The massive proportions of the teeth (large width relative to length) and particularly the shortness of the talonid of m3 are conspicuous on this specimen. As in all kollpaniines and North American mioclaenines, the entoconid and hypoconulid are connate (almost confluent) and the talonid basin is an obliquely oriented groove open anterolingually.
Measurements are provided on Table 5.
