Turlar
  • P. potens Ruskoni 1948 (turi)

Purranisaurus bu yo'q bo'lib ketgan tur o'rtasidan to oxirigacha dengiz timsoliformasining Yura davri davri Chili va Argentina. Ruskoni dastlab qabul qilingan Purranisaurus potens (the tur turlari) bo'lish a plesiosaur;[1] ammo, Gasparini aslida a ekanligini namoyish etdi metriorxinxid timsoliliform va bu kichik sinonim bo'lishi mumkin Metriorhynchus.[2]

Taksonomiya va filogeniya

2000-yillarda filogenetik tahlillar shuni ko'rsatdiki Purranisaurus alohida metriorhynchid turidir.[3][4] Keyingi tadqiqot genusni kengaytirdi Purranisaurus qo'shmoq Metriorhynchus casamiquelai va M. westermanni.[5] Qayta tavsifidan so'ng holotip ning tur turlari, endi faqat shu turga murojaat qilinadi Purranisaurus.
