Notobatrachus is an extinct genus of frog from the Lower Jurassic (Toarcian) Cañadon Asfalto Formation, Cañadón Asfalto Basin and Middle Jurassic La Matilde Formation, Deseado Massif of Patagonia, Argentina.[1] N. degiustoi is the most completely known Jurassic frog and has been recorded in many outcrops of the La Matilde Formation of the Deseado Massif in southern Patagonia.[2]
Most of the specimens of N. degiustoi are postmetamorphic individuals, snout-vent length between 90mm150mm. CPBA-V-14003 consists of disarticulated cranial and postcranial elements, and may correspond either to a late metamorphosing tadpole or an early postmetamorphic individual.[3]
