Passage: During the Late Permian, increasing aridity and the diversification of reptiles contributed into a decline in terrestrial temnospondyls, but semiaquatic and fully aquatic temnospondyls continued to flourish, including the large Melosaurus of Eastern Europe. Other temnospondyls, such as archegosaurids, developed long snouts and a close similarity to crocodiles, although they lacked the armor characteristic of the latter group. These temnospondyls included the largest known batrachomorph, the 9-m-long Prionosuchus of Brazil.

Question: What country was the largest of these creatures from?
Brazil
