About Arachana
Arachana is an extinct genus of rhinesuchid-like temnospondyl known from the Late Permian to Early Triassic Buena Vista Formation of northeastern Uruguay. Arachana was first named by Graciela Piñeiro, Alejandro Ramos and Claudia Marsicano in 2012 and the type species is A. nigra. It shares characteristics with both rhinesuchids and lydekkerinids, making it a transitional form between basal and more advanced stereospondyls.
