| Sumario: | About 100 specimens of the stem-anuran Notobatrachus degiustoi, from several localities of the Middle-Late Jurassic La Matilde Formation of southern Patagonia, were examined. This was aimed at clarifying numerous controversial aspects of its anatomy and executing an updated restoration of its skeleton, presented herein. Additionally, the few available immature specimens provide some data on the osteogenesis of this evolutionarily significant taxon. This study also revealed variation in the morphology of the adult sacral region, this variation being more evident among the specimens from one of the localities. |
