Comments

Diagnosis—Tristichopterid sarcopterygian referable to

Eusthenodon and differing from the type species by the combination

of: (1) a lack of contact between posterior supraorbital

and lacrimal such that the jugal contributes to the orbital

margin, and (2) contact between posterior supraorbital and intertemporal

in dermal view.
