The Irati Formation (Permian, Cisuralian) has several types of aquatic vertebrates, including species of Chondrichthyes. Two members of the Irati Formation are recognized, Assistência (upper) and Taquaral (lower). A sandy facies, at the base of the Taquaral Member, is noteworthy by the richness of the Chondrichthyes. The Holocephali are the most ab...

The South Yellow Sea Basin (SYSB) is an extension of the Lower Yangtze Block to the sea. The basin has undergone a complex tectonic-sedimentary evolution, and there has been no breakthrough in oil and gas exploration. Based on newly collected and processed well drilling data, cores, and seismic data of the central-southern SYSB and adjacent areas, ...
Temnospondyls were a group of early tetrapods notoriously abundant in late Palaeozoic-early Mesozoic terrestrial ecosystems, mainly in aquatic environments. Their extensive skeletal record is complemented by an abundant ichnological record. The diversity of track morphologies and trackway patterns indicates a wide array of locomotion styles in temn...
We report a new palaeontological assemblage from the Sakmarian (Early Permian) of Moulin de Latour in the Saint-Affrique Basin (southern France). Pelitic beds show the co-occurrence of arthropod (Diplopodichnus biformis) and tetrapod (Batrachichnus salamandroides and Dromopus lacertoides) tracks with jellyfishes (Medusina atava). Ichnofossils also ...
Karooprosbole magnifica gen. et sp. nov., oldest African cicadomorphan Prosbolidae, is described from middle Permiandeposits (Abrahamskraal Formation, Karoo Supergoup) at the Onder Karoo locality in South Africa. It is comparedto the genera currently included in Prosbolidae but also those in the Tettigarctidae: Cicadoprosbolinae. The limits anddefi...
We use a recently completed airborne magnetic and gamma-ray spectrometric survey, and new U/Pb and 40Ar/39Ar age determinations, to revise and clarify several aspects of Brook Street Terrane geology in the Takitimu Mountains. Steeply dipping and homoclinal Permian Takitimu Subgroup formations defined in the central part of the range can, with moder...

Though Paleozoic ray-finned fishes are considered to be morphologically conservative, we report a novel mode of fang accommodation (i.e., the fitting of fangs inside the jaw) in the Permian actinopterygian †Brazilichthys macrognathus, whereby the teeth of the lower jaw insert into fenestrae of the upper jaw. To better understand how fishes have acc...
The Xenacanthiformes are a Palaeozoic chondrichthyan order mainly present from the late Carboniferous to the early Permian deposits of the intra-mountainous basins of the European Hercynian Mountain Belt. This order is characterised by a tumultuous systematic history, resulting in various dubious species. At the same time, their palaeoecology is al...
The tetrapod tracksite from Le Bousquet (Permian, Red Sandstone Group from the Rodez Basin, southernFrance) was discovered during the second half of the 20th century. At this time, the tracksite was onlyweakly prospected and underestimated. Deposits exposed near Le Bousquet were recently re-investigated.New prospections led to: 1) enlargement of th...
