A new species of Notobatrachus (Amphibia, Salientia) from the Middle Jurassic of northwestern Patagonia
Notobatrachus degiustoi is the most completely known Jurassic frog and has been recorded in many outcrops of the La Matilde Formation of the Deseado Massif area in southern Patagonia. Herein, we erect a new species of the genus based on partially articulated remains collected from the Callovian Las...
