this more restricted sense. Promystriosuchus ehlersi Case, 1922 - Gregory (1962) and Hunt and Lucas (1991) referred this taxon to Paleorhinus on the genus level, and considered it to be a nomen dubium on the species level, due to the poor preservation of it holotype and only known specimen. Stocker and Butler (2013) suggested that P. ehlersi may not be referable to Paleorhinus and referred it to Phytosauria incertae sedis. Phylogeny The following cladogram, from Kammerer et al., 2016, shows the relationships of P. bransoni, P. angustifrons, and "P." sawini to other phytosaurs. The authors placed P. bransoni and P. angustifrons into the genus Parasuchus, owing to their close relationship with Parasuchus hislopi.
