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;〔 however, Gasparini demonstrated that it was in fact a metriorhynchid crocodyliform, and that may be a junior synonym of ''Metriorhynchus''.〔Gasparini Z. 1975. Revison de ?''Purranisaurus potens'' RUSCONI, 1948 (Crocodilia, Thalattosuchia) Los Thalattosuchia como un nuevo Infraorden de los Crocodilia. ''Actas del Congreso Geologico Argentino'' 5: 423–431.〕
==Taxonomy and phylogeny==
In the 2000s phylogenetic analysis has shown that ''Purranisaurus'' is a distinct metriorhynchid genus.〔Young MT. 2007. The evolution and interrelationships of Metriorhynchidae (Crocodyliformes, Thalattosuchia). ''Journal of Vertebrate Paleontology'' 27 (3): 170A.〕〔Young, Mark T., and Marco Brandalise de Andrade, 2009. "What is ''Geosaurus''? Redescription of ''Geosaurus giganteus'' (Thalattosuchia: Metriorhynchidae) from the Upper Jurassic of Bayern, Germany." ''Zoological Journal of the Linnean Society'', 157: 551-585.〕 A subsequent study expanded the genus ''Purranisaurus'' to include ''Metriorhynchus casamiquelai'' and ''M. westermanni''.〔Young, Mark T., Brusatte, Stephen L., Ruta, M., Andrade, Marco B. 2009.
