Abstract The Katian (Late Ordovician) saw the origin and early evolution of heliolitine tabulate corals; however, the group has not been well depicted owing to the lack of an adequately documented fossil record from this interval. In this paper, we systematically revise heliolitines from the upper Katian Hadabulaktag Formation of northern Kuruktag in northeastern Tarim, Xinjiang, China. 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.

Abstract To date, there is no published information on the Holocene bryozoans from India. In this study, we describe 10 species of lepraliomorph bryozoans collected from Holocene rocks along the Konkan coast between Maharashtra and Goa in western India. One of these species is new to science: Mucropetraliella malwanensis sp. nov. Five species are already known from elsewhere but are reported from India for the first time; four species are retained in open nomenclature because of insufficient material. These bryozoan assemblages likely inhabited warm water tropical to subtropical environments with euhaline to euryhaline salinities. The regional relationships show Indo-Pacific affinities. Mohan A.

Abstract Large Late Silurian burrows are preserved in fluviatile trough cross-bedded sandstones at Mount Bepcha and Mount William in the Grampians in western Victoria (Australia). 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.

摘要在澳大利亚维多利亚州西部格兰屏山脉的Bepcha山和William山的流槽交错层状砂岩中,发现了大型晚志留世洞穴。这些洞穴的腹面有两个平行的凹槽,可能是在沙质河道崩裂后,当它们在辫状河床的沙丘上挖洞时,留下痕迹的成对的腿形成的。这些洞穴在形态上不同于先前描述的洞穴和一个新的鱼属Gariwerdichnus igen。11月含一新种。11月是竖立的。洞穴的大小,连同其隆起的腹面,圆形的背表面和大的背外侧突起,以及半月形的回填,都指向巨大的多足类动物作为追踪者。这一结论进一步得到了大型双斑星isp的支持。(包括D. gouldi)在比普查山地层较高的单元中有相当大小的足迹;大型龙眼通常被认为是巨型多足类动物。可能形成warreni的早期多足类动物包括eoarthropleurids, arthropleurids或bennettarra样生物。Chris Gouramanis [chris.gouramanis@anu.edu.au],澳大利亚国立大学地球科学研究学院,澳大利亚首都领地,0200;Anthony, J.

Abstract Archaeomaenidae is a clade of Mesozoic freshwater fishes that includes the Australian species Archaeomaene tenuis, Madariscus robustus and Wadeichthys oxyops, the Antarctic Oreochima ellioti, the Chinese Zaxilepis qinglongensis, and the Mongolian Gurvanichthys mongoliensis. 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.

Abstract Sixteen species of trilobites are described from the Middle Ordovician (mid-Darriwilian, Da2) Stairway Sandstone and Stokes Siltstone at multiple spot localities from the Amadeus Basin, Northern Territory, central Australia. New trilobite taxa described include two new genera: Ghanaspis gen. nov. and Iridis gen. nov.; as well as five new species; Eisarkaspis jonesi sp. nov., Ghanaspis ritchiei gen. et sp. nov., Iridis schoonorum gen. et sp. nov., Lycophron titan sp. nov., and Norasaphus (Norasaphus) patersoni sp. nov. Of these, Lycophron titan sp. nov. is the largest species of trilobite so far documented from Australia and possibly the third largest in the world. Also redescribed is Basilicus thorntoni [=Asaphus (Megalaspis?) thorntoni] based on the recently rediscovered type material and additional specimens from elsewhere in the basin. *P.M.

Abstract Helcionelloids from the Korean Peninsula are revised based on a re-examination of type specimens and new material collected from the Cambrian Mungyeong Group of South Korea. 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.

Abstract Darriwilian to early Katian conodonts are documented herein from the Kuniutan, Datianba and Pagoda formations at the Daling section of southern Anhui Province, East China, representing a typical Ordovician succession of the marginal Yangtze Platform. 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.

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.

Abstract Abundant cone-shaped siliceous microfossils have been recovered from Upper Ordovician black shales of the Wufeng Formation in South China. 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.

Abstract The oldest fossils referable to the marsupial order Peramelemorphia (which includes modern bandicoots and bilbies) stratigraphically date from the upper Oligocene of Australia. Here we describe new ancient peramelemorphian remains from the Etadunna, Namba and Wipajiri formations, which fill gaps in the documented evolutionary history of the clade spanning some 10 million years. The identified taxa include three new species of Bulungu that incorporate the oldest stem peramelemorphian known to date from Faunal Zone A of the Etadunna Formation. We also report a new genus and species of potential thylacomyid, which pushes back the divergence of bilbies by ∼10 million years. Finally, we present a phylogenetic analysis that clarifies the evolutionary relationships of these new taxa with a reassignment of the genus Bulungu to Yaraloidea. Kenny J.

Abstract A new family of planthoppers, Szeiiniidae fam. nov., is described on the basis of a well-preserved forewing from the Upper Triassic Yanchang Formation of Huanglong County, Shaanxi Province, China. As the only specimen of the new family, Szeiinia huanglongensis gen. et sp. nov. differs from other families within Fulgoroidea by a unique combination of venation characters, and most significantly, the early branching of the MP vein, and low length/width ratio of the forewing. Our finding adds to the current understanding of morphological variability amongst planthoppers, and confirms high levels of diversity within Fulgoroidea at an early stage of the Mesozoic.
