HYAENODONTIDAE LEIDY, 1869

Diagnosis

Elongate, narrow skulls with narrow basicrania and high, narrow occiput; frontals concave between orbital regions; tritubercular to sectorial molars with carnassial blades in P 4, M 1, M 2, and M 1, M 2, and M 3 (except in Limnocyoninae and Machaeroidinae); M 3 present in most taxa; M 3 generally present; manus and pes mesaxonic, ranging from plantigrade to digitigrade; fibula articulated with calcaneum; astragalar−cuboid articulation reduced or absent; terminal phalanges compressed and fissured at tip; central, scaphoid, and lunar unfused (except perhaps for the hyainailourine Pterodon ). Distribution

Africa, Asia, Europe, and North America; Selandian (Palaeocene) to Serravallian (Miocene).

Subfamilies

Apterodontinae Szalay, 1967; Arfiinae Solé, 2013; Hyaenodontinae Leidy, 1869; Hyainailourinae Pilgrim, 1932; Indohyaenodontinae Solé et al., 2013b; Koholiinae Crochet, 1988; Limnocyoninae Wortman, 1902;?Machaeroidinae Matthew, 1909; Proviverrinae Schlosser, 1886 ; Sinopinae Solé, 2013; Teratodontinae Savage, 1965.

Note

The systematic position of the sabre-toothed Machaeroidinae amongst ‘Creodonta’ is presently uncertain (see Gunnell, 1998).
