Isohyaenodon is an extinct genus of hyaenodont mammal of the family Hyainailouridae. Remains are known from early Miocene deposits in Kenya, East Africa.

Description[]

Isohyaenodon is distinguished from Hyaenodon in having more robust molars, lower molars with a subequal paraconid and protoconid, and upper molars with a more well-developed protocone.^[1]

Taxonomy[]

Isohyaenodon was considered possibly the same genus as from the same region by Van Valen (1967),^[2] but subsequent studies have rejected this assumption.^[3]^[4]

Isohyaenodon pilgrimi Savage, 1965 was formerly assigned to this genus, but has been renamed Exiguodon.^[4]
