*probable synonyms Docodon (meaning 'beam tooth') is an extinct docodont mammaliaform from the Late Jurassic of western North America.

[4] Docodonts had more complex shaped teeth than other early non-mammalian mammaliaforms, with piercing and crushing surfaces that would have allowed members of this family to eat a wider range of food types.

Unlike many of its coexisting mammal relatives from the Mesozoic, Docodon is known from a large number of teeth and jaws of differing growth stages.

This has made it possible to study the growth of this docodontan, and has revealed how docodont jaws change from juvenile stages to adulthood.

Its height is estimated at 10 centimeters with an approximate weight of 30 grams, making it one of the larger mammaliaforms known from the Morrison Formation.
