CHANARESUCHUS

Character 4: in the holotype of Chanaresuchus the upper tooth row presents a sharp inflexion of its alveolar margin between the premaxilla and maxilla articulation, which results in a downturned ventral premaxillary margin ( PULR 07 ). As a result the character state (1) has been rescored as (0) .

Character 8: in Chanaresuchus a pair of aligned foramina is present between the lacrimal and the prefrontal (PULR 07). The character state (1) has been scored instead of (?).

Character 29: in Chanaresuchus PULR 07 an intertuberal crest is present on the parabasisphenoid plate. The character state (0) has therefore been introduced instead of (1).

Character 30: in Chanaresuchus the ventral surface of the parabasisphenoid lacks a semilunar depression (PULR 07). As a result, the character state (1) has been introduced instead of (0).

Character 37: in the holotype of Chanaresuchus the pair of vomerines lacks teeth. Accordingly, the character state has been rescored as (1) instead of (?).

Character 54: in the available materials of Chanaresuchus that we were able to examine, no interclavicle is preserved (PULR 07; PVL 6244). Thus, the character state (1) has been rescored as (?).

Character 57: in PVL 6244 a large notch is present in the anterior margin of the scapulocoracoid contact. Accordingly, the character state has been rescored as (1) instead of (0).

Character 80: in PVL 6244 the metatarsal is longer than 50% of the total tibial length. As a result, the character state (1) has been introduced instead of (0). Character 83: if digit V of Chanaresuchus is absent (Dilkes & Sues, 2009), this character is not applicable for this taxon. Thus, the character state (-) has been introduced instead of (1).
