Parasuchidae is a clade of phytosaurs more derived than Diandongosuchus, a basal phytosaur. This family was phylogenetically defined by Christian Kammerer and colleagues in 2015 as the last common ancestor and all descendants of Wannia scurriensis, Parasuchus hislopi, and Mystriosuchus planirostris. It encompasses nearly all phytosaurs, including early Parasuchus-grade forms as well as a more restricted clade of more specialized phytosaurs. This more restricted clade is traditionally known as the family Phytosauridae and more recently as the subfamily Mystriosuchinae, defined by Kammerer et al. 2015 as the last common ancestor and all descendants of Mystriosuchus planirostris and Angistorhinus grandis.
