“…Gondwana-affinity Early Permian successions in the Lhasa, Tengchong and Baoshan blocks have been identified (e.g. Nie et al, 1993;Wopfner, 1996;Jin, 2002;Metcalfe, 2002;Wang et al, 2003). These successions are characterized by glacio-marine Gondwana sedimentary facies and a Gondwana-affinity biota (e.g.…”

“…And chronologically, only in Late Carboniferous to Early Permian those blocks had cold/cool water fauna due to Gondwanan glaciation. Thus, the Early Permian small and solitary corals found from the Dingjiazhai Formation in the Baoshan block, the Kongshuhe Formation in the Tengchong block, the Angjie Formation in the Lhasa block, and the Zhanjin Formation in the Qiangtang block are probably cold water inhabitants related to Gondwanan glaciation [22]. These small blocks that belong to the Cimmerian continent were located at the northern margin of the Gondwana land.…”

“…Wang et al [17] summarized five different environments of small, solitary, non-dissepimented corals: 1) lower part of continental shelf at warm and barrierless coast; 2) deep water region at continental margin; 3) cold water shallow sea; 4) warm shallow sea with abundant clastic supply; 5) normal shallow sea at biotic crisis events. Wang et al [18][19][20][21][22] also studied Mississippian rugose corals from Baoshan, West Yunnan, Southwest China and suggested that occurrences of the Cyathaxonia fauna are related to mud-rich, deep, and low energy environments.…”

“…Although most abundant small, solitary, and non-dissepimented corals occur in Yunnan [6,7,18,[20][21][22][31][32][33], Tibet (Xizang) [4,5,15,48,49], Xinjiang [16,23,24,[40][41][42]50], and Inner Mongolia [37,38,54], there is no special distribution pattern. Small solitary rugose corals belonging to the Cyathaxonia fauna also occur in many areas of China such as Guangxi, Guizhou, Hunan, Jiangsu, and others, which are paleobiogeographically Tethyan region during Carboniferous and Permian time.…”

The Cyathaxonia faunas are widely distributed in the Carboniferous and Permian strata in China. The fauna in China contains 12 families and 40 genera, and can be recognized as three episodes from Early Carboniferous to the end-Permian in terms of their occurrence and composition: 1) Mississippian; 2) Pennsylvanian-Early Permian; 3) Middle Permian-Late Permian. They were relatively abundant in episodes 1 and 2. A decrease of family Antiphyllidae and an increase of family Hapsiphyllidae can be observed from Early Carboniferous to the end-Permian. Two case studies are given to illustrate the bio-facies of the Cyathaxonia faunas, which are from the Mississippian of Baoshan, West Yunnan and the Mississippian of Chaohu, South Anhui. In both areas, Cyathaxonia faunas occur just below the large dissepimented solitary and compound coral assemblages in a continuous sequence in a single section, which implies that the occurrence of these small, non-dissepimented solitary corals is not strictly related with Gondwanan or Peri-gondwanan cold water environment, but might be controlled by such benthic conditions as deeper, mud-rich, quieter, and darker sedimentary environments.Cyathaxonia fauna was first introduced by Hill [1]. In the investigation of rugose corals from Scotland, she recognized three coral assemblages based on the relationships between coral occurrences and sedimentary facies, i.e., the major coral biofacies, in Carboniferous: 1) Cyathaxonia fauna, 2) Caninid-Clisiophyllum Fauna, and 3) Reef-Coral Fauna. The first assemblage is also known as the small, solitary, non-dissepimented coral fauna due to their simple morphological features that characterized all those corals of this fauna. Incidentally, the taxon Cyathaxonia does not necessarily always occur in this fauna.The occurrences of compound colonies of modern corals, especially the coral reefs, are an index of low latitude temperate zone or tropic areas with moderate temperature, indicating a warm and clean seawater environment. The small solitary corals in present sea, however, not only appear in the coral reefs, but also live in various ecological conditions, e.g., deep water or middle latitude regions [2]. The study on the extinct rugose corals and their ecological significance has had a long history among coral experts [3]. There are few arguments over the ecology of the reef building colonial and large solitary rugose corals. But many disagreements remain on the ecology of small solitary non-disepimented rugose corals. These morphologically simple, widely distributed and slowly evolving taxa in the Carboniferous and Permian are of little use in biostratigraphic aspects but bear relatively highly on the paleoecology and paleogeography. Some Chinese researchers hold that the small, solitary, non-dissepimented rugose corals in the Carboniferous and Permian were cold-water inhabitants [4][5][6][7]. Such an opinion was originated from a relatively abundant occurrence of small solitary rusose corals in Tibet and

A new foraminiferal fauna is reported from the upper part of the Xiala Formation in the Zhari Namco section in the central Lhasa Block, which contains three species of fusulines and 26 species of small foraminifers. The presence of Reichelina and Codonofusiella in the fauna suggests a Wuchiapingian age. A review of the Lopingian faunas in several localities in the Lhasa Block indicates that this block was under a shallow marine environment during the Lopingian, rather than an uplifted terrestrial environment as previously recognized. The Lopingian palaeobiogeography as well as the sequences of the Lhasa Block differs greatly from the adjacent South Qiangtang, Karakorum and South Pamir blocks, and the Tethys Himalaya region of the Indian Plate. It further suggests that the Lhasa Block was separated from the South Qiangtang Block in the north by the Bangong‐Nujiang Ocean and the Tethys Himalaya area in the south by the Neotethys Ocean during the Lopingian time. Furthermore, the dissimilarity of the Guadalupian and Lopingian strata and faunas between the Lhasa and Karakorum blocks and similarity between the Lhasa and Tengchong blocks, may suggest that the Lhasa and Tengchong blocks were linked together during the Permian.
