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… 

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.


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 and

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.

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. Three

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 and

The Permian-Triassic transition : Historical review of the most important ecological crises with special emphasis on the Iberian Peninsula and Western-Central Europe

One of the most important climatic and biological crises of the history of the Earth occurred 250 m.a. ago, during the transition from the Permian to the Triassic. During the Permian, all of the



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.

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 material

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.

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.

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 the

ABSTRACT The cranial anatomy of the primitive Carboniferous temnospondyl Cochleosaurus bohemicus is described herein from several large, presumably adult, skulls. This new morphological data modifies
