Talk:Paleorhinus

Chatterjee (2001) petitioned the ICZN to replace the original type specimen of Parasuchus hislopi, a fragmentary premaxilla, with a complete skeleton. The ICZN (2003) officially designated a complete skeleton, ISIR 142, as the neotype of Parasuchus. Thus, Parasuchus is confined to India but the ICZN ruling does not render Paleorhinus a junior synonym of Parasuchus. After all, a revision of Paleorhinus is overdue (Stocker 2010).

Paleorhinus paraphyly
The cladistic analysis of Stocker (2010) recovers the genus Paleorhinus is paraphyletic with respect to more advanced phytosaurs, with P. bransoni (the type species) and P. sawini being closer to advanced phytosaurs than P. scurriensis. However, Stocker did not include other putative synonyms of Paleorhinus in her analysis (Francosuchus, Ebrachosuchus, Arganarhinus, Mesorhinosuchus, and Promystriosuchus). Until a revision of Paleorhinus is undertaken, I would recommend placing Mesorhinosuchus, Francosuchus, and Promystriosuchus in separate pages.
