Acanthodian,onychodontid and osteolepidid fish from the middle-upper Taemas Limestone (Early Devonian), Lake Burrinjuck,New South Wales

A meagre ischnacanthid acanthodian fauna, known from fragmentary dentigerous jawbones from Lake Burrinjuck, Yass district, New South Wales, consists of three taxa: Taemasacanthus narrengullenensis, Taemasacanthus cooradigbeensis and an indeterminate ischnacanthid. The fossils are from three Early Devonian (Emsian) units at Taemas: the Bloomfield Limestone Member, the Currajong Limestone Member and the Warroo Limestone Member, which constitute the middle-upper parts of the Taemas Limestone (Murrumbidgee Group); and from Unit 6 of the ‘Upper Reef formation’ at Wee Jasper. Whereas ischnacanthid acanthodian remains are increasingly rarer in the higher levels of the Taemas Limestone, remains of onychodontid and osteolepidid fishes are relatively abundant; Onychodus yassensis sp. nov., Onychodus sp. and isolated osteolepidid teeth are locally common.     

Early Devonian Pacificocoelia sinica (Brachiopoda) from Northeastern Inner Mongolia

Leptocoeliid brachiopods from the Early Devonian Baruntehua Formation of Dong Ujimqin Qi, northeastern Inner Mongolia were assigned to Leptocoelia by Su (1976) and Zhang(1983), and subsequently to Pacificocoelia by Hou & Boucot (1990). Transverse serial sections of Pacificocoelia sinica are illustrated hère, for the first time, based on topotype specimens. The known geographic range o Pacificocoelia is from northern China, North America, South America and Kazakhstan (Eastern Americas Realm and also occurs in east-central Asia). Atlanticocoelia is regarded hère as a junior synonym of Pacificocoelia.     

Sewn Boats of Southeast Asia: the stitched‐plank and lashed‐lug tradition

This article updates research into the sewn‐boat traditions of Southeast Asia with recent finds that provide evidence of the transition from stitched planks with lashed‐lug frames to planks fastened with dowels and locked dowels alongside lashed‐lug frames. The differences between Southeast Asian, East Asian, and Indo‐Arabic boatbuilding are discussed and the meaning of anomalies, such as the Maldivian dhonis, examined. Considering the known history of trade and exchange throughout the South China Sea and the Indian Ocean, the lack of hybridization between boatbuilding traditions is noted.     

Microdictyon plates from the lower Cambrian Ajax Limestone of South Australia: Implications for species taxonomy and diversity

A small assemblage of isolated Microdictyon plates is described from the lower Cambrian Ajax Limestone, Mt Scott Range (Flinders Ranges), South Australia. Microdictyon plates are primarily known from single, isolated, perforated phosphatic sclerites; only one species (M. sinicum) from the Chengjiang Lagerstätte is known from soft-bodied preservation of the complete organism. The isolated plates from South Australia display a wide range of morphologies potentially reflecting: 1, considerable diversification within the group at this time; 2, extensive intraspecific morphological variation; 3, different plate morphotypes along the trunk of the animal; or 4, significant ontogenetic variation in successive growth stages. The South Australian specimens are similar to several individual sclerites described from other Cambrian palaeocontinents, but appear closest to faunas described from South China. Problems associated with the taxonomy of isolated Microdictyon plates are discussed, including the lack of knowledge associated with intraspecific and/or ontogenetic variability and how individual plate morphology may relate to size or relative position along the length of the complete organism.     

China's Emergence and Impact on Technology in East Asia: The Case of Machinebuilding

Two Taiwan-based economists estimate the technology content of exports by the machinebuilding industry of the East Asia region during 2004-2008, using comparative analysis to clarify changes in the relative competitiveness of four East Asian nations (China, Japan, South Korea, and Taiwan) accompanying the formation of a regional trading bloc and production networks. In particular, they examine the technology content of these countries' machinebuilding sub-industries' exports within the Southeast Asian market (documenting the rise of the machinebuilding industry in China) as well as the penetration of Japanese, South Korean, and Taiwanese sub-industries into China's market. The results point to areas of emerging competition among China, South Korea, Japan, and Taiwan for East Asian markets, which can only be expected to intensify in the future.

Archaeocyaths from Yorke Peninsula,South Australia and archaeocyathan Early Cambrian zonation

Zhuravlev, A. Yu., & Gravestock, D. I., 1994:03:28. Archaeayaths from Yorke Peninsula, South Australia and archaeocyathan Early Cambrian zonation. Alcheringa 18, 1–54. ISSN 0311-5518.

Two assemblages of archaeocyaths are documented from Lower Cambrian outcrops and drillholes on Yorke Peninsula. South Australia. The older assemblage (11 species) occurs in the uppermost Kulpara Formation and conformably overlying basal Parara Limestone, and is equivalent to Lower Faunal Assemblage II in the Flinders Ranges. The younger assemblage (28 species plus Acanthhcyathus and Rodiocyathus) occurs in the Koolywurtie Member near the top of the Parara Limestone. Equivalent taxa are widespread in the Flinders Ranges, western New South Wales and Antarctica. Archaeocyathan distribution is now sufficiently well known to propose three assemblage zones and two informal assemblages for regional correlation. No new taxa have been added, but Erugatocyathus scutatus (Hill) and Pycnoidocyathus latiloculatus (Hill), hitherto known only from Antarctica, are found in the upper assemblage on Yorke Peninsula. Irregular archaeocyathan systematics are discussed, the ontogeny of Archaeopharetra irregularis (Tylor) clarified, and Kruseicnema Debrenne. Gravestock & Zhuravlev, represented by K. gracilis (Gordon), is fully described.     

A new late Oligocene to early Miocene species o Apatopygus (Echinoidea: Cassiduloida) from the Maltese Islands

The occurrence of Apatopygus gaudensis sp. nov. in the upper part of the late Oligocene (Chattian) Lower Coralline Limestone division, and the lower part of the early Miocene (probably late Aquitanian) Lower Globigerina Limestone division of the Maltese Islands (Central Mediterranean), is the first confirmed record of Apatopygus outside the Australia-New Zealand region. Apatotygus vincentinus (Tate, 1891) from the middle to late Eocene of southern Australia is the earliest known occurrence of the genus, possibly suggesting that Apatotygus may have evolved earlier in the Australasian region, or merely that it is yet to be discovered in pre-Oligocene strata in the Mediterranean area.     

A global analysis of distribution and endemism within Late Llandovery (Telychian) brachiopods

Cocks, L.R.M. & Jiayu, R. 10 July 2019. A global analysis of distribution and endemism within Late Llandovery (Telychian) brachiopods. Alcheringa 43, 406–422. ISSN 0311–5518

The genera of brachiopods of early Silurian (late Llandovery: Telychian) age have been critically reviewed and are listed from the major continental areas: South China, Avalonia-Baltica, Laurentia, Siberia and adjacent areas, and Gondwana (including the adjacent Kazakh terranes, Southwest Tien Shan and Iran). All those continents lay within tropical latitudes, apart from the South American sector of Gondwana, which hosted the Clarkeia Fauna, the earliest constituent of the largely high-latitude Devonian Malvinokaffric Province in the southern hemisphere. Additionally, the then northern (today’s southern) part of the Siberian continent, which included parts of Mongolia and North China, was at temperate latitudes in the northern hemisphere so that it hosted the Tuvaella Fauna, which was also dominated by endemic brachiopod genera. Of the 202 genera listed, 50 are endemic to one of the six regions, and a further eight must have lived during Telychian times since they are known from both the underlying Aeronian and the overlying Sheinwoodian.

Pragian and lower Emsian (Lower Devonian) conodonts from Liujing,Guangxi, South China

LU, J.-F., QIE, W.-Q. & CHEN, X.-Q., July 2016. Pragian and lower Emsian (Lower Devonian) conodonts from Liujing, Guangxi, South China. Alcheringa 40, xxx–xxx. ISSN 0311-5518.

Lower Devonian (Pragian and Emsian) conodonts are described from the Liujing section in Guangxi, South China, highlighting the phylogeny of early polygnathids and establishing the basis for faunal correlations with deposits throughout the world. Records of Eognathodus kuangi sp. nov. and E. nagaolingensis Xiong increase the biodiversity of the Pragian eognathodids in South China and represent intermediate stages and probably the latest eognathodids in the evolutionary succession from Eognathodus to Polygnathus. During this evolutionary succession, the degeneration of the sulcus (or the flattening of the upper platform surface) is the most important morphological change, especially in the eognathodid lineage. Polygnathus trilinearis, P. pireneae and P. sokolovi are recognized together for the first time in South China. The contemporaneous occurrences of the kitabiformis and sokoloviformis morphs of P. pireneae with P. sokolovi and their respective similarities to P. kitabicus and P. sokolovi suggest that the latter two species are phylogenetically linked with P. pireneae. Evidence from the Liujing section also favours Polygnathus probably having evolved from Eognathodus in a tropical or subtropical area.

Lower Devonian ischnacanthid fish (Gnathostomata: Acanthodii) from the Taemas Limestone,Lake Burrinjuck,New South Wales

Dentigerous jawbones of ischnacanthid acanthodians from the Lower Devonian Currajong Limestone Member and the lower part of the Bloomfield Limestone Member of the Taemas Limestone (Murrumbidgee Group: early Emsian) in the Murrumbidgee valley at Good Hope, Taemas district, and the Goodradigbee valley at Wee Jasper are described. Three taxa of Taemasacanthus are recognized: T. sp. cf. erroli Long, 1986; T. narrengullenensis sp. nov. and T. cooradigbeensis sp. nov. Fragmentary fin spine remains and scales are also described.     

Ordovician (Bendigonian,Darriwilian to Gisbornian) faunas from the northern Molong Volcanic Belt of central New South Wales

Diverse shallow water assemblages dominated by brachiopods, molluscs, sponges and stromatoporoids, and a tabulate coral, in the Wahringa Limestone Member (Darriwilian-Gisbornian), and Yuranigh Limestone Member (Gisbornian, or early Late Ordovician) of the Fairbridge Volcanics, are documented from the northern Molong Volcanic Belt in central N.S.W. New species described include Billingsaria spissa, Shlyginia printhiensis and Sowerbyites? wahringaensis. Elements of the Wahringa Limestone Member assemblage such as Labechia banksi, Labechiella regularis, and Maclurites cf. M. florentinensis are biogeographically significant in displaying strong similarities with contemporaneous Tasmanian faunas. The brachiopods Ishimia and Shlyginia from the Yuranigh Limestone Member are recognised for the first time outside Kazakhstan and Sibumasu. The presence of the brachiopod Anoptambonites in allochthonous limestone breccia within the lower Fairbridge Volcanics provides evidence of a regionally significant hiatus of 10–15 Ma duration separating this unit from the underlying Hensleigh Siltstone, of Early Ordovician (Bendigonian) age. The sponge Archaeoscyphia?, from allochthonous limestones in the latter formation, is the oldest macrofossil yet described from the Lachlan Fold Belt in central N.S.W.     

Chonetoidea (Brachiopoda) from the Lopingian (Late Permian) of South China

Ten species of the superfamily Chonetoidea from the Lopingian (Late Permian) of South China are described or revised. A review of all recorded Chonetoidea species from the Lopingian (Late Permian) of South China indicates that some 22 species of five genera can be recognised. Species of Tethyochonetes and Neochonetes are characteristic in the lithofacies dominated by mudstone, siltstone or siliceous rocks in the Lopingian and some argillaceous limestone and clay rock facies near the Permian-Triassic boundary. New taxa are Neochoneles (Zhongyingia) subgen. nov., Neochonetes (Huangichonetes) subgen. nov. and Tethyochonetes flatus sp. nov.

A new trilobite species from the upper Rhuddanian (lower Silurian) of South China,and its biogeographical implications

Anacaenaspis yanpingensis sp. nov., from the lower Niuchang Formation (upper Rhuddanian, lower Llandovery, lower Silurian), is the first record of this genus from South China. The biogeographical distribution of Anacaenaspis and some other trilobite genera from South China (e.g., Gaotania, Hyrokybe, Aulacopleura and Raphiophorus) in the Llandovery evidences faunal exchanges between Avalonia–Baltica, Laurentia, Australia and South China. We attribute these dispersals to prevailing ocean currents, and especially equatorial countercurrents, which would have propagated dispersals during the Rhuddanian, shortly after the end-Ordovician mass extinction.     

Assessment of the Southern Dispersal: GIS-Based Analyses of Potential Routes at Oxygen Isotopic Stage 4

This paper explores the geographic and environmental context of the Southern Dispersal Route, which has been proposed as a migratory route for Homo sapiens from East Africa to Australasia during oxygen isotope stage (OIS) 4 (71–59 kyr). A series of assumptions and constraints garnered from modern hunter-gatherer observations are used to build a model of coastal foragers, which is then integrated with high-resolution physiographic analyses to produce a potential dispersal route along the coastline of the Indian Ocean. Paleoenvironmental conditions that may have supplied critical resources or served as obstacles to human colonization are identified and discussed in regards to human subsistence, the speed of migration, and demographic expansion. These factors suggest that rapid dispersals along coastlines and river valleys would have occurred upon the initial expansion out of Africa, but slowed as populations expanded demographically into South Asia and the Sunda Shelf. This also suggests that archaeological signatures relating to the earliest modern Homo sapiens are more likely to be recovered in South Asia.     

New Early Triassic Lingulidae (Brachiopoda) genera and species from South China

Two new genera, Sinolingularia gen. nov. and Sinoglottidia gen. nov., together with three new species, Sinolingularia huananensis gen. et sp. nov., Sinolingularia yini gen. et sp. nov. and Sinoglottidia archboldi gen. et sp. nov., are described on the basis of a large collection of well-preserved specimens from several sections straddling the Permian – Triassic boundary in South China.     

Late Silurian pentameride brachiopods from Yass and Molong,New South Wales

The five known species of pentameride brachiopods from the Yass Syncline Ludlow (LateSilurian) succession, belonging to the superfamilies Pentameroidea, Gypiduloidea and Clorindoidea, are fully revised; no new species are recognised. The pentameroids Conchidium sp. cf. hospes and Aliconchidium yassi are confined to the Bowspring Limestone Member (Silverdale Formation). The gypiduloid Ascanigypa glabra and externally homeomorphic clorindoids Barrandina wilkinsoni and Clorinda minor replace them in the overlying Barrandella Shale Member, the last two extending into the Yarwood Siltstone Member (Black Bog Shale). Clorinda minor is also possibly present in the Rainbow Hill Member (Rosebank Shale). All except C. minor are uncommon to rare components of the Yass brachiopod fauna. Clorinda molongensis, a species of uncertain mid- to late Silurian age from the Molong Limestone, is also revised. Aliconchidium and Barrandina are known only from Yass, whereas Clorinda is cosmopolitan. Conchidium alsois widespread, but C. hospes is a species from the Prague Basin probably also known from the Urals and the Tien Shan. Ascanigypa is another Prague Basin taxon, recently recognised in Arctic Canada.     

Late Mississippian (Early Carboniferous) brachiopods from the western Daba Mountains,central China

Qiao L. & Shen S.Z., September 2012. Late Mississippian (Early Carboniferous) brachiopods from the western Daba Mountains, central China. Alcheringa 36, 287–309. ISSN 0311–5518.

Fifteen brachiopod species in 12 genera are described for the first time from four intervals in the middle and upper parts of the Zhanpo Formation at the Huoyanxi section near Zhenba in the western Daba Mountains, southern Shaanxi, central China. The Zhenba brachiopod fauna is dominated by diverse and abundant species of Productida, together with some species of Athyridida, Orthida, Orthotetida and Spiriferida. It ranges from late Viséan to Serpukhovian in age based on the presence of Gigantoproductus species in association with diagnostic foraminifera and conodonts. This fauna generally shows palaeobiogeographical links with the palaeoequatorial realm, including Western Europe, the Moscow Basin, the Ural Mountains, Japan, eastern Tibet and South and North China. Its closest palaeobiogeographical affinity is with South China assemblages rather than those of North and Northwest China, therefore, indicating that the Zhenba area was palaeogeographically close to the South China Block and relatively far from the blocks in Northwest China (e.g., the Qilian Mountains and Qaidam Basin, Kunlun Mountains, Tarim Basin and Tianshan Mountains) during the late Viséan–Serpukhovian.
