Phylum: Chordata
Class: Sauropsida
(unranked): Mesoeucrocodylia

Family: Metriorhynchidae
Genus: Purranisaurus
Rusconi, 1948 [1]
Species
  • P. casamiquelai Gasparini & Chong, 1977 [2]
  • P. westermanni Gasparini, 1980 [3]
  • P. potens Rusconi, 1948 (type)

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.[4]

Taxonomy and phylogeny

Recent 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]

Valid species

  • P. casamiquelai: Middle Jurassic of Chile (Callovian);[2]
  • P. westermanni: Middle Jurassic of Chile (Callovian). Although previously considered a junior synonym of P. casamiquelai,[8] it has been revalidated;[9]
  • P. potens: End Jurassic of Argentina (Tithonian).
