Purranisaurus
Purranisaurus is an extinct genus of marine crocodyliform from the Middle to Late Jurassic period of Chile and Argentina. Rusconi originally regarded Purranisaurus potens (the type species) to be a plesiosaur;[1] however, Gasparini demonstrated that it was in fact a metriorhynchid crocodyliform, and that may be a junior synonym of Metriorhynchus.[2]

Taxonomy and phylogeny
In the 2000s phylogenetic analysis has shown that Purranisaurus is a distinct metriorhynchid genus.[3][4] A subsequent study expanded the genus Purranisaurus to include Metriorhynchus casamiquelai and M. westermanni.[5] Following the re-description of the holotype of the type species, only that species is now referred to Purranisaurus.
