Classification and phylogeny
Taxonomy
Isohyaenodon was considered possibly the same genus as
Leakitherium from the same region by Van Valen (1967), but subsequent studies have rejected this assumption.
Isohyaenodon pilgrimi Savage, 1965 was formerly assigned to this genus, but has been renamed Exiguodon.
