Poorly known tarsiiform belonging to the subfamily Anaptomorphinae, family Omomyidae. Found in early to middle Eocene deposits from the Rocky Mountain region of North America. Three to seven species, two of which may be in an ancestor - descendant relationship; Tetonius homunculus is suggested as an ancestor for at least one species. Dental formula: or, depending on the species. Absarokius differs from other anaptomorphines in the enlargement of the third and fourth premolars and in thickening of the mandible, suggesting a diet of hard morsels.
