Sichuanosuchus is an extinct genus of crocodyliform from the Late Jurassic and possibly Early Cretaceous of China.
Systematics
Poll and Norell (2004) recovered Sichuanosuchus as sister to Shantungosuchus and Zosuchus based on the presence of a ventrally deflected posterior region of the mandibular rami. [1] Buscalioni (2017) recovered Sichuanosuchus as sister to Shantungosuchus, Zosuchus, and Shartegosuchidae, [2] and Dollman et al. (2018) went further by erecting Shartegosuchoidea for the clade formed by Shartegosuchidae, Sichuanosuchus, Zosuchus, and Shantungosuchus. [3]
