New fossils from the Upper Permian Moradi Formation of northern Niger provide an insight into the faunas that inhabited low-latitude, xeric environments near the end of the Palaeozoic era (∼ 251 million years ago). We describe here two new temnospondyl amphibians, the cochleosaurid Nigerpeton ricqlesi gen. et sp. nov. and the stem edopoid Saharastega moradiensis gen. et sp. nov., as relicts of Carboniferous lineages that diverged 40–90 million years earlier. Coupled with a scarcity of… Expand

New Permian fauna from tropical Gondwana
This new fauna constitutes a new biogeographic province with North American affinities and clearly demonstrates that tetrapod dispersal into Gondwana was already underway at the beginning of the Permian. Expand
A review of the Guadalupian (middle Permian) global tetrapod fossil record
Abstract Until recently, the Guadalupian (middle Permian) tetrapod fossil record was known almost exclusively from the Karoo Basin of South Africa and the Cis-Urals region of Russia, limitingExpand
First African record of micromelerpetid amphibians (Temnospondyli, Dissorophoidea)
Abstract Recent fieldwork in late Carboniferous (Kasimovian) continental sediments of the Souss Basin, south-central Morocco, yielded two skeletons of small branchiosaur-like micromelerpetids. It isExpand
Temnospondyls are the most abundant constituent of the Colonia Orozco Local Fauna of the Uruguayan Buena Vista Formation (Parana Basin), contrasting with that observed at most latest Permian andExpand
New continental Carboniferous and Permian faunas of Morocco: implications for biostratigraphy, palaeobiogeography and palaeoclimate
Abstract Late Palaeozoic sediments in central Morocco and the High Atlas Mountains document the development of this area during the formation of the Mauretanide part of the Hercynian orogeny.Expand
Permian anomodonts: Paleobiogeography and distribution of the group
In the Late Permian, higher anomodonts, dicynodonts, reached an almost global distribution. The wide distribution makes this group an important tool in Upper Permian biostratigraphy. ThreeExpand
Late Permian (Lopingian) terrestrial ecosystems: A global comparison with new data from the low-latitude Bletterbach Biota
It is shown that terrestrial ecosystems were structured and provincialised at high taxonomic levels by climate regions, and that latitudinal distribution is a key predictor of ecosystem compositional affinity. Expand

Temnospondyl diversity of the Permian-Triassic Colonia Orozco Local Fauna (Buena Vista Formation) of Uruguay
Temnospondyls are the most abundant constituent of the Colonia Orozco Local Fauna of the Uruguayan Buena Vista Formation (Paraná Basin), contrasting with that observed at most latest Permian andExpand
The vertebrate fauna of the Upper Permian of Niger – VIII. Nigerpeton ricqlesi (Temnospondyli: Cochleosauridae) and tetrapod biogeographic provinces
New cranial material of the derived cochleosaurid Nigerpeton ricqlesi is described and compared to five other Upper Permian assemblage with bipartite taxon–locality occurrence networks, and the fauna of the Moradi Formation is inferred. Expand


Evolutionary Patterns Among Permo-Triassic Therapsids*
Synapsids form the bulk of tetrapod diversity from Early Permian to Middle Triassic times and thus can provide critical information on the nature of the Permo-Triassic extinction in the terrestrial realm. Expand
A Temnospondyl amphibian from the Rio do Rasto Formation, Upper Permian of southern Brazil
A partially preserved lower jaw constitutes the holotype of Bageherpeton longignathus n. g., n. sp., a probable archegosaurid amphibian, which is here assigned to the Platyoposaurinae. The materialExpand
A cochleosaurid temnospondyl amphibian from the Middle Pennsylvanian of Linton, Ohio, U.S.A.
Adamanterpeton ohioensis is a very rare component in the large Linton vertebrate assemblage and may have been a relatively terrestrial form, perhaps similar to Cochleosaurus florensis from the contemporaneous lycopsid–trunk locality at Florence, Nova Scotia. Expand
Continental Permian and Triassic vertebrate localities from Algeria and Morocco and their stratigraphical correlations

Phylogenetic analysis of Russian Permian dicynodonts (Therapsida: Anomodontia): implications for Permian biostratigraphy and Pangaean biogeography
The phylogeny presented here suggests that the genus Dicynodon is paraphyletic, and there appears to be some endemism among Late Permian dicynodont faunas, but a Gondwanan origin is equally likely given the data at hand. Expand
Permian Phytogeographic Patterns and Climate Data/Model Comparisons
The most recent global “icehouse‐hothouse” climate transition in earth history began during the Permian. Warmer polar conditions, relative to today, then persisted through the Mesozoic and into theExpand
