Gower and Sennikov (2000) find the supposed differences between the species to be invalid (premaxillary shape; posteroventral expansion of maxillary ramus; antorbital fossa; posterior jugal process length; pineal foramen; intercentra; triple-headed ribs), except for the possible closer association of teeth and aveolar bone in Vjushkovia. They recommend synonymizing the species. I have no personal opinion, as this is well outside my range of expertise.

Thanks to those who responded to my queries on Postosuchus. While we're on the subject of non-dinosaurian archosaurs, are the erythrosuchids Garjainia and Vjushkovia considered synonymous, with the former having priority? In some resources, I see Vjushkovia triplocostata, the type species, classified under Garjainia. Thanks again, Andrew McDonald
