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 Leakitherium 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]

gollark: Think about it. Wouldn't *you* like Minoteaur existence?

gollark: I am unfortunately generally too incompetent to create it, but I need it to exist, for purposes.

gollark: Or make Macron make Minoteaur.
