Purranisaurus is an extinct genus of marine crocodyliform from the Late Jurassic aged Vaca Muerta of Argentina and Toqui Formation of Chile.[2] 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.[3] It was about 3.3 m (11 ft) long.[4]
Taxonomy and phylogeny
[edit | edit source]
In the 2000s phylogenetic analysis has shown that Purranisaurus is a distinct metriorhynchid genus.[5][6] A subsequent study expanded the genus Purranisaurus to include Metriorhynchus casamiquelai and M. westermanni.[7] Following the re-description of the holotype of the type species, only that species is now referred to Purranisaurus.
