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.[5][6]
Isohyaenodon pilgrimi Savage, 1965 was formerly assigned to this genus, but has been renamed Exiguodon pilgrimi.[6]
