Abstract
The fragmentary material described in this account supplements the initial report on the temnospondylous labyrinthodonts of the Lower Triassic Fremouw Formation of Antarctica given by Colbert and Cosgriff (1974). Some of the fragments are referred to the lydekkerinid Cryobatrachus kitchingi, others (with question) to the brachyopid Austrobrachyops jenseni, and still others to the family Rhytidosteidae without generic or specific determination. The rhytidosteid is a new entry for the tetrapod faunal list of the Fremouw Formation. Taphonomy is considered, and it is shown that the lithologie contexts of the Fremouw Formation which are productive of temnospondyls are consonant with the view that brachyopids, lydekkerinids, and rhytidosteids were tetrapods primarily adapted to the fresh-water and water-edge habitats of the general flood plain regime under which the Fremouw Formation was deposited.
