Paralligatoridae
Introduction '''Paralligatoridae''' is an extinct family of neosuchian crocodyliforms that existed during the Jurassic and Cretaceous periods. It includes the genera ''Paralligator'', ''Brillanceausuchus'', ''Kansajsuchus'', ''Shamosuchus'', ''Scolomastax'', ''Sabresuchus'', ''Rugosuchus'', ''Batrachomimus'' and ''Wannchampsus'', as well as the yet-unnamed "Glen Rose form".
Evolution Phylogenetic analyses of crocodyliforms find Paralligatoridae to nest within Neosuchia, a large clade (evolutionary grouping) that also includes modern crocodylians. In crocodyliform phylogeny, paralligatorids are usually found near the base of Neosuchia, outside the clade Eusuchia, which includes crocodylians and their closest relatives. Below is a cladogram from Montefeltro ''et al.'' (2013) showing the phylogenetic relationships of Paralligatoridae:
