HOLOTYPE: PIN 4174 View Materials /2 a dorsoventrally crushed skull and mandible of a juvenile individual.
TYPE LOCALITY: Ulan Malgait Formation, Shar Teg, Mongolia.
REFERRED MATERIAL: IGM 200/50, an anterior portion of the skull including rostrum and palatal and dentary bones recovered from Ulan Malgait Formation, Shar Teg, Mongolia.
REVISED GENUS AND SPECIES DIAGNOSIS: *Palatines small and enclose anterior palatal fenestra; *mediolaterally narrow and anteroposteriorly elongate anterior palatal fenestra; *anterior palatal fenestra begins at level of midpoint of suborbital fenestra and ends beyond anterior margin of suborbital fenestrae; *choana positioned posteriorly on the palate and enclosed by pterygoids.
The name Shartegosuchoidea is proposed for the clade Shartegosuchidae + Shantungosuchus , Sichuanosuchus , and Zosuchus , and we define it here as the least-inclusive clade including Shartegosuchus , Shantungosuchus , Zosuchus , and Sichuanosuchus . The definition of Shartegosuchidae is revised as the most inclusive clade that includes Shartegosuchus and Nominosuchus but not Zosuchus .
