Smilodectes gracilis had a dental formula of 2:1:4:3 on both the upper and lower jaw (Fleagle, 1988). This species had a relatively short snout and rounded frontal bone as compared to other notharctines (Fleagle, 1988). This species lacked symphyseal fusion (Martin, 1990). This species had comparatively reduced olfactory bulbs and a more expanded visual cortex, and this suggests that this was a diurnal species (Fleagle, 1988). This species had a cranial capacity of 9.5 cc (Martin, 1990). This species had an average body mass of around 2.1 kilograms (Fleagle, 1988).
Smilodectes gracilis was found on the continent of North America and occurred during the middle Eocene (Fleagle, 1988).
Based upon dental morphology this was a folivorous species (Fleagle, 1988).
Based upon the postcranial skeleton this species was a vertical clinger and leaper (Martin, 1990).
