MARASUCHUS

Character 2: in Marasuchus the only available cranial elements corresponds to a right maxilla, preserving the horizontal ramus and the base of the ascending process (PVL 3870), probable right squamosal and postorbital (PVL 3872), and a basicranium (PVL 3870, 3872). Accordingly, the morphology of the dorsal region of the antorbital fossa, constituted by the distal end of the ascending process of the maxilla and dorsal end of the lacrimal, is currently unknown. In this regard, the state (?) has been introduced instead of (1) in this taxon.

Character 3: in Marasuchus the available maxilla preserves the anterior and ventral boundaries of a well-developed internal antorbital fenestra (PVL 3870). Accordingly, this character has been codified as (1) instead of (?) in Marasuchus .

Character 34: in the available maxillary teeth of Marasuchus (PVL 3870), the crowns are distally curved. In this regard, the character state (1) has been changed instead of (?).

Character 35: the crowns of the maxillary teeth of Marasuchus are labiolingually compressed (PVL 3870), and as a result the character state has been codified as (1) instead of (?) for this character.
