A new Late Silurian plant with complex branching from Xinjiang,China

Wang Yi, Fu Qiang, Xu Honghe, & Hao Shougang, June, 2007. A new Late Silurian plant with complex branching from Xinjiang, China. Alcheringa 31, 111-120. ISSN 0311-5518.

A new fossil plant is described from the middle part of the Wutubulake Formation (late Pridoli) of Xinjiang, China. This plant demonstrates at least two orders of branching. The first-order axis has pseudomonopodial branching with alternately attached second-order axes. Fertile units are alternately inserted along the second-order axis, and consist of a branching system and two sporangia at each tip. Sporangia are narrowly obovate with rounded apex and tapering base. This plant is characterized by more complex branching than other Silurian and Early Devonian plants, and is named Wutubulaka multidichotoma gen. et sp. nov., and placed under open higher-order nomenclature.     

Early Carboniferous brachiopod faunas from the Baoshan block,west Yunnan,southwest China

38 brachiopod species in 27 genera and subgenera are described from the Yudong Formation in the Shidian-Baoshan area, west Yunnan, southwest China. New taxa include two new subgenera: Unispirifer (Septimispirifer) and Brachythyrina (Longathyrina), and seven new species: Eomarginifera yunnanensis, Marginatia cylindrica, Unispirifer (Unispirifer) xiangshanensis, Unispirifer (Septimispirifer) wafangjieensis, Brachythyrina (Brachythyrina) transversa, Brachythyrina (Longathyrina) baoshanensis, and Girtyella wafangjieensis. Based on the described material and constraints from associated coral and conodont faunas, the age of the brachiopod fauna from the Yudon Formation is considered late Tournaisian (Early Carboniferous), with a possibility extending into earlyViséan.     

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.     

Organic-walled microfossils from the Early Cambrian of South Australia

Microfossils which are hollow, possess a two-layered vesicle wall, and occur as single elements or, more rarely, as compound forms, have been recovered from the Early Cambrian Heatherdale Shale, on the Fleurieu Peninsula, South Australia. The microfossils, which range in size from 4 to 14.5 μm, are informally and tentatively assigned to the genus Sphaerocongregus Moorman 1974. Superficially they resemble forms assigned to Pyritosphaera Love 1958 and its probable junior synonym, Bavlinella Shepeleva 1962. Topotypes of these genera, however, have yet to be studied using SEM techniques, and their morphologic details remain uncertain. The organic composition of the present microfossils is supported by energy-dispersive X-ray analyses. Samples of the Heatherdale Shale were also analysed using pyrolysis techniques; the organic matter is, however, over-mature with respect to petroleum generation, and no geochemical assessment of original kerogen type is possible.     

A new Llanvirnian Isograptus from the D. murchisoni Shales of Abereiddy Bay,Wales

Isograptus ovatus davidensis subsp. nov. is described from the D. murchisoni Shales of Abereiddy Bay, Wales. This discovery gives further support to the correlation of the murchisoni Zone with the upper part of the Darriwil Stage of Victoria.     

Late Carboniferous to Early Permian brachiopod faunas from the Bachu and Kalpin areas,Tarim Basin,NW China

Terrestrial reptile remains are very rare in the Lower Cretaceous of South Australia, but include the holotype of the small theropod Kakuru. Here, we review this taxon and other archosaur specimens collected from the Bulldog Shale (Aptian) of Andamooka and Coober Pedy. Kakuru possesses no unique characters or character state combinations and is regarded as a nomen dubium, representing an indeterminate tetanuran theropod. Two other specimens (a left metatarsal and astragalus) can be referred to Dinosauria, but the identity of several other specimens (phalanges and a centrum) can only be resolved to the level of an indeterminate archosaur.     

A new dragonfly,Austroprotolindenia jurassica (Odonata: Anisoptera), from the Upper Jurassic of Australia

Beattie, R.G. & Nel, A., June 2012. A new dragonfly, Austroprotolindenia jurassica (Odonata: Anisoptera), from the Upper Jurassic of Australia. Alcheringa, 189–193. ISSN 0311-5518.

Austroprotolindenia jurassica gen. et sp. nov., a new Mesozoic Australian dragonfly, is described from the Talbragar Fossil Fish Bed (Upper Jurassic) of eastern Australia. It shows some similarities with the Eurasian Mesozoic petalurid family Protolindeniidae, but its incomplete state of preservation prevents us assigning it to a particular anisopteran clade.

Remains of an Eocene skink from Queensland

Azurduya gen. nov. (Brachiopoda: Camarotoechiidae) is described from Early Carboniferous sequences in the Argentine Precordillera and northern Chile. Marine assemblages and the palynoflora associated with this genus suggest a Tournaisian age. The type species Azurduya chavelensis (Amos, 1958) is reviewed and redescribed from material from the type locality. Additional material from equivalent localities in the Rio Blanco Basin (La Rioja and San Juan provinces, Argentine Precordilera) has been used to understand ontogenetic changes as well intraspecific variation. Azurduya cingolanii sp. nov. is proposed.     

New sinoalids (Insecta: Hemiptera: Cercopoidea) from Middle to Upper Jurassic strata at Daohugou,Inner Mongolia,China

Fu, Y., & Huang, D., December 2018. New sinoalids (Insecta: Hemiptera: Cercopoidea) from Middle to Upper Jurassic strata at Daohugou, Inner Mongolia, China. Alcheringa 43, 246–256. ISSN 0311-5518.

A new fossil genus with three species of Sinoalidae, Parasinoala daohugouensis gen. et sp. nov., Parasinoala minuta gen. et sp. nov., Parasinoala magnus gen. et sp. nov., from the Middle to Upper Jurassic Haifanggou Formation at Daohugou, Inner Mongolia, northeastern China, is described and illustrated. The new genus differs from other sinoalids by the tegmen with RA having 2–3 branches, MP with 3–4 branches and MP of hind wings with two branches, which indicates the terminal branches of RA and MP are highly variable within Sinoalidae. The new discovery greatly increases the palaeodiversity of sinoalids in the early assemblage of the Yanliao biota from the Daohugou beds.

Vertebrate microremains from the presumed earliest Carboniferous of the Mansfield Basin,Victoria

The Agnostida are the most important part of the fauna of the Abbey Shales, which is the best-known middle St David's (Middle Cambrian) sequence in Britain. Revision of Illing's (1916) collections allows a correlation of the Paradoxides hicksii fauna with Westergaard's (1946) Ptychagnostus atavus-Tomagnostus fissus Zone, and the Paradoxides davidis fauna with Westergaard's Hypagnostus parvifrons Zone and Ptychagnostus punctuosus Zone (based on the Swedish sequence). A Metadiscus sp. is described. Six species of Condylopygidae are discussed, of which three show a pygidial ‘fringe’. Eleven species of Quadragnostinae, three of Ptychagnostinae (one showing a hypostome), and four of Tomagnostinae (including young growth-stages) are illustrated or discussed. Two species of Diplagnostidae, one species of Phalacroma and two of Phalagnostus are illustrated.

Magnaxyela rara gen. et sp. nov. and Abrotoxyela curva sp. nov. (Xyelidae, Macroxyelinae, Gigantoxyelini) are described from the Middle Jurassic Jiulongshan Formation at Daohugou Village, Inner Mongolia, China. The two new species are confidently assigned to tribe Gigantoxyelini of subfamily Marcroxyelinae based on their wing venation and various other morphological characters. Magnaxyela rara is established based on the following forewing characters: pterostigma sclerotized completely, Sc two-branched and meeting R before origin of Rs, 1-Rs as long as 1-M, but shorter than Rs?+?M, R curved bewteen 1r-rs and 2r-rs and cell 2r longer than 1r. Abrotoxyela curva is differentiated from congeneric forms by the two-branched vein Sc of the forewing, Sc2 short and inclined towards the base of the wing, 1-Rs, 1-M and Rs?+?M nearly equal in length, crossvein 1m-cu longer than 1cu-a. The fossils described herein increase the diversity of the Mesozoic Xyelidae.

A new genus and species of Steninae from the late Eocene of France (Coleoptera,Staphylinidae)

Cai, C., Clarke, D.J., Huang, D. & Nel, A., 2014. A new genus and species of Steninae from the late Eocene of France (Coleoptera, Staphylinidae). Alcheringa 38, 557–562. ISSN 0311-5518.

A remarkable new genus and species of rove beetle, Eocenostenus fossilis gen. et sp. nov., is described and figured based on one well-preserved specimen from the late Eocene of Monteils (near Alès, Gard, France). Eocenostenus is definitively placed in the extant subfamily Steninae, based on the combination of dense and coarse body punctation, globular and protruding eyes, exposed and closely spaced antennal insertions on the vertex, and six visible abdominal terga. Eocenostenus differs from the two extant stenine genera Stenus and Dianous most notably in the structure of the prothorax, which is strongly transverse and with unusual anterolateral projections, and in the anteriorly placed antennal insertions. This new discovery highlights the palaeodiversity of a genus-poor subfamily and suggests that the early diversification of Steninae is probably complicated.

Palynology of glacial sediments from the Guandacol Formation (Middle Carboniferous) in the Cerro Bola area,Paganzo Basin,Argentina

The palynoflora of surface samples of glacial deposits from the Guandacol Formation in the Cerro Bola area of the Argentinian Paganzo Basin is documented. The existence of glacial related diamictites in this area has been previously ignored. The fossiliferous levels are located in section B of the formation, which corresponds to the earlier stages of deglaciation. The assemblage contains abundant monosaccate pollen grains whose global incoming is not older than early Namurian (Middle Carboniferous). Many species of this palynoflora are present in equivalent stratigraphic sequences of Argentina and can be referred to Sub-biozone A of the Raistrickia densa-Convolutispora muriornata Biozone (Namurian-Stephanian). New species described here are Cyclogranisporites rinconadensis and Tricidarisporites gutii.     

Protodammara reimatamoriori,a new species of conifer (Cupressaceae) from the Upper Cretaceous Tupuangi Formation,Chatham Islands,Zealandia

Mays, C. & Cantrill, D.J., January 2018. Protodammara reimatamoriori, a new species of conifer (Cupressaceae) from the Upper Cretaceous Tupuangi Formation, Chatham Islands, Zealandia. Alcheringa XXX, X–X. ISSN 0311-5518.

Isolated conifer female reproductive structures are common fossil elements from Cenomanian (ca 99–94 Ma) charcoal- and resin-rich beds of the Tupuangi Formation, Chatham Islands, southwest Pacific Ocean. Recent findings have proposed that these are the oldest fossil evidence of serotiny, a highly successful fire-adaptive reproductive strategy common among tree species living in fire-prone areas today. Herein, we systematically describe the external morphological and anatomical features of these fossils, by employing a combination of manual extraction and neutron tomography techniques. We propose a new species of conifer, Protodammara reimatamoriori, and a re-examination of fossil material of the Protodammara type species facilitated an emendation of the genus. Protodammara shares numerous features with extant Cunninghamia, Taiwania, Athrotaxis, and several extinct taxa of Cupressaceae, and is interpreted as an extinct lineage of the early-divergent ‘taxodioid Cupressaceae’ stem group.

A new damsel-dragonfly (Odonata: Anisozygoptera: Campterophlebiidae) from the earliest Jurassic of the Junggar Basin,northwestern China

Zheng, D., Wang, H., Nel, A., Dou, L., Dai, Z., Wang, B. & Zhang, H. 27 June 2019. A new damsel-dragonfly (Odonata: Anisozygoptera: Campterophlebiidae) from the earliest Jurassic of the Junggar Basin, northwestern China. Alcheringa XX, X–X. ISSN 0311-5518.

A new genus and species of campterophlebiid damsel-dragonfly, Jurassophlebia xinjiangensis gen. et sp. nov., is described from the Lower Jurassic Badaowan Formation in the Junggar Basin, northwestern China. Jurassophlebia differs from all other campterophlebiid genera in having PsA in the same orientation as the distal branch of AA, and in its uniquely open subdiscoidal cell with very acute apical angle in the hind wing. The new discovery adds to the Asian diversity of damsel-dragonflies in the earliest Jurassic.

A new athyridacean brachiopod from the Carboniferous of Rawdon Vale,New South Wales

Rawdonia nasharae gen. et sp. nov. is described from the Carboniferous Carsonville and Berrico Creek Formations at Rawdon Vale, N.S.W. Rawdonia is distinguished from other athyridaceans by: the possession of a smooth brachial valve; a cardinal process which is rod-like, bordered by extensions of the socket plates, and has an alveolus or pit at the base; the lack of a cardinal plate; and the lack of well-defined dental plates. In New South Wales Rawdonia nasharae ranges from the Delepinea aspinosa Zone to the Rhipidomella fortimuscula Zone.     

China’s urban ideology: new towns,creation cities,and contested landscapes of memory

ABSTRACT

This paper argues that “the urban” has emerged as the most significant ideological realm in contemporary China. In developing this argument, I suggest an alternative approach to how we theorize urbanization in China. Seeking to avoid the dichotomized analyses that often characterize scholarship on China’s urbanization, the paper suggests reading “the urban” as an ideological device. Such a reading calls for an analytical distinction between the city as a technology of socialist party-state planning and government and urbanization as a messy social process over which the state struggles for control. It also calls for a recognition of the ways that ideology itself has shifted dramatically in China, from the Mao-era centrality and coherence of class struggle and its overriding goal of proletarianization to a much less coherent post-reform message of “stability”. The paper begins with a brief discussion of ideology and Gramsci’s notion of “common sense” in a Chinese register. It then considers the film 24 City, directed by Jia Zhangke, as a template for understanding urban spaces as sites of conflict between the city as an ideological device and urbanization as a social process. New urban spaces are then explored in an effort to tease out their complex and contradictory ideological renderings. I conclude with an argument about the openness and contradictions of China’s urban spaces and how an ideological analysis can resist the kind of theoretical closure that much work on urbanization in China seems to aim for.
