We examine previously identified type material and describe new specimens from the type horizon. Our investigation shows that the Tarim heliolitine assemblage includes protoheliolitids Khangailites sinkiangensis, Wormsipora sinkiangensis, and Wormsipora orientalis, the plasmoporellids Plasmoporella subtilis and Plasmoporella maxima, and a proporid Propora squameosa. These taxa compositionally compare with coeval faunas from the Kazakstan terranes, and more distantly with South China and Australia. *Yunong Cui [ yncui@nigpas.ac.cn], State Key Laboratory of Palaeobiology and Stratigraphy, Nanjing Institute of Geology and Palaeontology and Center for Excellence in Life and Paleoenvironment, Chinese Academy of Sciences, 39 East Beijing Road, Nanjing 210008, PR China; University of Chinese Academy of Sciences, Beijing 100049, PR China; Guangxu Wang [gxwang@nigpas.ac.cn], State Key Laboratory of Palaeobiology and Stratigraphy, Nanjing Institute of Geology and Palaeontology and Center for Excellence in Life and Paleoenvironment, Chinese Academy of Sciences, 39 East Beijing Road, Nanjing 210008, PR China.","PeriodicalId":272731,"journal":{"name":"Alcheringa: An Australasian Journal of Palaeontology","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114191286","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These burrows have ventral surfaces with two parallel grooves likely formed by the trace-makers’ paired legs as they burrowed through dunes on braided-river beds, probably after avulsion of sandy channels. The burrows are morphologically distinct from previously described burrows and a new ichnogenus Gariwerdichnus igen. nov. containing a single new ichnospecies G. warreni isp. nov. is erected. The size of the burrows, together with their ridged ventral surface, rounded dorsal surface with large dorsolateral protuberances, and meniscate backfill, point towards giant myriapods as the tracemakers. This conclusion is further supported by the presence of large Diplichnites isp. (including D. gouldi) trackways of comparable size in a stratigraphically higher unit at Mount Bepcha; large D. gouldi are typically attributed to giant myriapods. Early myriapod groups that could have formed G. warreni include eoarthropleurids, arthropleurids, or a Bennettarthra-like organism.

A comprehensive redescription of the genus Archaeomaene demonstrates that Madariscus robustus is a junior synonym of Archaeomaene tenuis, and thus constitutes an ontogenetic body-size series. A detailed revision of W. oxyops and O. ellioti also confirms their phylogenetic placements within Archaeomaenidae. Furthermore, the incompletely documented taxa Z. qinglongensis and G. mongoliensis are recognized as archaeomaenids. Archaeomaenidae therefore comprises a geographically widely distributed radiation of stem teleosts or teleosteomorphs that is closely related to the archetypal Eurasian clade Pholidophoridae.

The fauna comprises Coreospira rugosa, Hampilina goniospira, Dorispira pacifica, cf. Igorella coreanica, and Helcionelloid indet. Coreospira and Hampilina are distinguished from other helcionelloids by their angular junction between dorsal and lateral surfaces, and from each other by the presence or absence of a rounded ridge along the junction, respectively. The Korean helcionelloids range stratigraphically from the base of Maochuangian to the lower Hsuchuangian using the chronostratigraphical scheme from North China; this correlates with upper Stage 4 to the lower Wuliuan Stage. Unusual septal features, such as complex suture lines in Hampilina and a central circular structure in the simple convex septa of Coreospira, occur in the apical region of the Korean helcionelloids, and could have implications for univalved molluscan evolution.

A total of 5228 conodont specimens, assigned to 20 genera and 29 species, were recovered from 56 carbonate samples. Seven conodont biozones are recognized, including (in ascending order) the Lenodus antivariabilis, the L. variabilis, the Yangtzeplacognathus crassus, the Dzikodus tablepointensis, the Y. jianyeensis, the Baltoniodus alobatus and the Hamarodus brevirameus biozones. They provide new data for an improved biostratigraphic correlation of these formations regionally and internationally. Furthermore, the detailed conodont biostratigraphy reveals a hiatus between the top of the Kuniutan Formation and its overlying Datianba Formation at the Daling section, missing the stratigraphic interval spanning from the Eoplacognathus suecicus Biozone (middle Darriwilian) to the lower part of the Pygodus anserinus Biozone (lower Sandbian). Based on the conodont data from the Daling section, the conodont biodiversity shows a prominent increasing trend within the D. tablepointensis Biozone (middle Darriwilian) in the Kuniutan Formation and a moderately increasing trend in the H. brevirameus Biozone (lower Katian) in the Pagoda Formation.

They occur in the Hirnantian Metabolograptus extraordinarius Biozone. An investigation of their internal structure conducted using focused ion beam-scanning electron microscope (FIB-SEM) and transmitted light microscope shows that the specimens are possibly composed of three parts: cephalis, thorax and foot. Robust, longitudinal costae are developed, sometimes branching at the thorax. The geological distribution of these microfossils in South China indicates that they occurred in a restricted epicontinental sea on the Upper Yangtze Platform, which was connected to the open ocean in the north. It seems likely that these microfossils have a limited temporal range relative to the Late Ordovician Mass Extinction (LOME) in the early Hirnantian. In the absence of coeval graptolites or other index fossils, their occurrence therefore provides an age marker for the LOME, and has utility for future shale gas exploration in the Wufeng Formation.
