Brachiopods from the Permian–Triassic boundary beds at the Selong Xishan section, Xizang (Tibet), China

The brachiopods from the Waagenites Bed and the upper part of the Coral Bed above and below the Permian–Triassic sequence boundary at the Selong Xishan section of southern Xizang suggest a rich brachiopod fauna existing in Selong, and a rapid invasion of Tethyan brachiopods into the Himalayas at the very end of the Permian. A transgression beginning from the Waagenites Bed and a rapid flooding at the beginning of the Triassic is reflected by changes in composition of the Permian brachiopod assemblages in Selong. However, the dominant forms in the Permian–Triassic sequence boundary beds, including Krotovia, Spiriferella and Neospirifer, extend from the underlying beds of the Selong Group without significant evolutionary change. A brief discussion of each taxon and descriptions of two new species, Stenoscisma selongensis and Martinia attenuatelloides, are presented.

Late Devonian (Famennian) brachiopod Yunnanella from the Junggar Basin, northern Xinjiang, China

The Late Devonian (Famennian) brachiopod Yunnanella is reported from the western Junggar Basin, northern Xinjiang, on the basis of Yunnanella hanburii (Davidson) and Yunnanella sp.

Gondolininae, a new carboniferous productide brachiopod subfamily

The upper Lower Carboniferous, Serpukhovian (=Chesterian) productide brachiopod genus Gondolina , from China, is made the type for the new subfamily Gondolininae in the Aulostegidae. Sectioned specimens reveal an unusual posterior dorsal flap of shell partially covering the ventral interarea.
