Purranisaurus is an extinct genus of marine crocodyliform from the Middle to Late Jurassic period of Chile and Vaca Muerta of 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] It was about 3.3 m (11 ft) long.[3]
Taxonomy and phylogeny
In the 2000s phylogenetic analysis has shown that Purranisaurus is a distinct metriorhynchid genus.[4][5] A subsequent study expanded the genus Purranisaurus to include Metriorhynchus casamiquelai and M. westermanni.[6] Following the re-description of the holotype of the type species, only that species is now referred to Purranisaurus.
