A new Permian gastropod assemblage from the Roadian (Middle Permian) Khao Khad Formation, Saraburi Group (Lopburi Province, Central Thailand) which is part of the Indochina Terrane, has yielded one of the most diverse Permian gastropod faunas known from Thailand. A total of 44 gastropod species belonging to 30 genera are described herein, including thirteen new species and one new genus. The new genus is Altotomaria. The new species are Bellerophon erawanensis, Biarmeaspira mazaevi, Apachella thailandensis, Gosseletina microstriata, Worthenia humiligrada, Altotomaria reticulata, Yunnania inflata, Trachydomia suwanneeae, Trachyspira eleganta, Heterosubulites longusapertura, Platyzona gradata, Trypanocochlea lopburiensis and Streptacis? khaokhadensis. Most of the species in the studied assemblage represent vetigastropods  (35.6%) and caenogastropods (26.7%) and most of the species belong to Late Palaeozoic cosmopolitan genera. The studied faunas come from shallow water carbonates that are rich in fusulinids, followed by gastropods, ostracods, bivalves and brachiopods. The gastropod assemblage from the Khao Khad Formation shares no species with the gastropod assemblages from other Permian formations in Thailand, the Tak Fa Limestone and the Ratburi Limestone. However, it is similar to the Late Permian gastropod faunas from South China of the Palaeo-Tethys, therefore it suggests that the Indochina Terrane was not located far from South China.

Three productidine brachiopods ofHaydenella, Paraplicatifera,andCompressoproductusare recovered from the Tak Fa Formation (Wordian, Middle Permian) of the upper Saraburi Limestone Group exposed at Khao Wong of central Thailand (the western margin of the Indochina Terrane). The latter two genera are new to the Permian of Thailand, and the new speciesParaplicatifera thaicais proposed herewith. Some taxonomic and nomenclatural problems in relation to the three genera are discussed. The assemblage suggests endemism for a Middle Permian marine faunule of the Indochina Terrane.

The small Paleozoic protozygopteran family Permagrionidae comprises 11 described species in 5 genera from the Lower Permian Chekarda and Solikamsk localities in Russia (Zalessky, 1948; Nel et al., 2012) and Salagou Formation in France (Nel et al., 1999; Fate et al., 2013), the Middle Permian Soyana and Kargala localities in Russia (Martynov, 1932; Martynov, 1937; Nel et al., 2012), and the Upper Permian Bodie Creek Head locality in Malvinas Tillyard (1928). Here we describe the new species, Epilestes rasnitsyni sp. nov. from the Ufimian of Perm Territory, which is characterized by specific arrangement of veins in the petiole and the unique preservation of body structures.

The paper considers a new species of gleicheniacean fern Tumidopteris astra Naugolnykh sp. nov. from the Lower Permian (Kungurian) and the Middle Permian (Roadian) deposits of the Pechora coal-basin, Russia. The new species is characterized both by macromorphology of the fertile and sterile pinnules and micromorphology of the sori and sporangia. Morphology of the most closely related leptosporangiate ferns is discussed.

Isolated teeth from the Middle Permian (early Guadalupian) Kaibab Formation of Arizona are described as a new species of the xenacanth shark genusBransonella. Bransonella tribulan. sp. is a small tooth in which the intermediate cusp is 65% of the length of the principal cusps and the cristae on the labial face extend down over the base, covering it, and bifurcating to form distinctive double crested ridges. Fin spines from the same localities in the Kaibab Formation show the characteristic xenacanth feature of a double row of large thorn-like denticles along the posterior margin.Bransonella tribulan. sp. is the only xenacanth shark known from the Kaibab Formation at present, however, due to the lack of articulated material the fin spines are attributed to ?Bransonella tribulan. sp. The ecomorphology ofBransonellasuggests a primitive, small, gracile, marine xenacanth that fed near the sea floor like the modern catsharks (Scyliorhinidae).

New fusulinid collections from the Baoshan Block in southwest China necessitate paleobiogeographic reevaluation of the Mid-Permian fusulinids in this region. From Xiaoxinzhai Section in the southern Baoshan Block, 32 fusulinid species of nine genera are described and illustrated. Among them,Eopolydiexodina parvais a new species, and elements of Neoschwagerinidae and Verbeekinidae are confirmed. The studied fusulinids are ascendingly grouped into three biozones: theSchwagerina yunnanensisRange Zone,EopolydiexodinaAbundance Zone, andSumatrina annaeRange Zone. The lower two could be assigned in age to the Murgabian and the uppermost one to the Midian. Midian fusulinids are for the first time reported from the Baoshan Block. In terms of fusulinid paleobiogeography, these three assemblages should belong to the western Tethyan Province A because of the presence ofEopolydiexodinaand characteristic Tethyan genera, e.g.,Verbeekina, Sumatrina, and Pseudodoliolina.Moreover, these assemblages may occupy a comparatively high latitudinal region within Tethyan Realm, judging from the overall low diversity.
