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.  相似文献

Taylor, P.D., & Gordon, D.P., December, 2007. Bryozoans from the Late Cretaceous Kahuitara Tuff of the Chatham Islands, New Zealand. Alcheringa 31, 339-363. ISSN 0311-5518.

Fourteen bryozoan species are described from the Campanian – Maastrichtian Kahuitara Tuff of Pitt Island, substantially increasing the known diversity in this deposit from the two species recorded previously and making it the most diverse bryozoan biota yet described from the Cretaceous of Australasia. Nine of the Kahuitara Tuff bryozoans are cyclostomes, four are cheilostomes, and one is a shell-boring ctenostome. Seven new species are described: Ceriocava hakepaensis sp. nov., Tholopora australis sp. nov., Crisidmonea lanauzeorum sp. nov., Cookobryozoon cretacea sp. nov., Chiplonkarina preeceorum sp. nov. Chiplonkarina bifoliata sp. nov. and Aechmella rangiauriensis sp. nov. The remaining species are left in open nomenclature because of preservational deficiencies or lack of taxon-diagnostic gonozooids. The ctenostome family Cookobryozoidae is subsumed in the Terebriporidae. The new family Chiplonkarinidae is proposed for anascan cheilostomes previously assigned to the paraphyletic Electridae and distinguished by having primarily erect colonies with long, tubular zooids reminiscent of stenolaemates. None of the Kahuitara Tuff bryozoan species is known elsewhere, but all apart from one genus occur in roughly coeval deposits. No families regarded as particularly characteristic of the austral post-Cretaceous are evident. The relatively large number (three) of co-occurring species of Chiplonkarina is notable, as is the dominance of cyclostomes and the first record of Tholopora in the Southern Hemisphere.

Muir, L.A. & Botting, J.P., December, 2007. Graptolite faunas and monaxonid demosponges of the Cyrtograptus lundgreni event (late Wenlock, Silurian) interval from the Orange district, New South Wales. Alcheringa 31, 375-395. ISSN 0311-5518.

Three monograptid and five retiolitid graptoloids, and one species of sponge, are described from late Wenlock sections (Cyr. lundgreni and Co. ludensis biozones) at Spring Creek and Wallace Creek, near Orange, New South Wales, Australia. The sponge Janussenia orangense gen. et sp. nov. is the first monaxonid demosponge to be described from the Australian Silurian. An object containing broken Testograptus testis, and interpreted as the faecal pellet of a predator or scavenger on graptoloids, is described.

Late Permian rugose corals are described from a limestone unit of the Gua Musang Formation at Selborne Estate, Padang Tengku area, Pahang, peninsular Malaysia. These include one genus, Iranophyllum, which is reported for the first time from Malaysia, with two new species Iranophyllum aequabilis and I. pahangense belonging to Waagenophyllidae. A Late Permian age is confirmed by a Paleofusulina–Colaniella–Reichelina foraminiferal fauna co-preserved with the corals.

Zheng, Y., Chen, J., Zhang, J. & Zhang, H., 6 August 2019. New fossil sawflies (Hymenoptera, Xyelidae) from the Middle Jurassic of northeastern China. Alcheringa 44, 115–120. ISSN 0311-5518.

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.

Hampe, O., Witzmann, F. & Asbach, P., 2014. A benign bone-forming tumour (osteoma) on the skull of a fossil balaenopterid whale from the Pliocene of Chile. Alcheringa 38, xxx–xxx. ISSN 0311–5518.

A pathology of the fossil baleen whale ‘Megapterahubachi from the early Pliocene of Chile is described. It is a bony outgrowth on the left side of the supraoccipital, which is interpreted as a benign bone-forming tumour (osteoma). This diagnosis is based on X-ray imaging and CT scans of the abnormal bone, revealing a homogeneously dense internal structure with no evidence for lytic areas. The osteoma described here in ‘Megaptera’ hubachi is the first unequivocal evidence of a bone tumour in a cetacean, fossil or extant.

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.  相似文献

ABSTRACT

The Imperial German Army (Deutsches Herr) was unique among the combatants in World War One (WW1) in issuing to a proportion of its soldiers a bayonet whose blade back was fashioned as a saw. A common belief developed quickly among the Allies that these sawback bayonets were weapons specifically intended to inflict a particularly vicious type of wound. After setting out the origins of this class of weapon and explaining their real purpose, the two main types of sawback bayonet available to the Deutsches Heer during WW1 are then concisely described. Its reputation as a weapon of especial barbarity is outlined, along with an overview of bayonet use in combat between the mid-nineteenth century and 1918, as evidenced by official sources, highlighting the lack of any specific contemporary references to the use of or the wounds caused by sawback bayonets. The article concludes by detailing the contemporary German sources relevant to its withdrawal from service use in 1917.  相似文献

Cantrill, D. J., & Drinnan, A. N., 1994:03:28. Late Triassic megaspores from the Amery Group, Prince Charles Mountains, East Antarctica. Alcheringa 18, 71–78. ISSN 0311-5518.

Megaspores referable to the genera Cabochonicus Batten & Ferguson 1987 and Minerisporites Potonié 1956 are a common component of the palaeoflora recovered from the Jetty Member within the Flagstone Bench Formation of the Amery Group. The known ranges of these two genera, in conjunction with the macrofloral remains, suggest a Late Triassic age. Two new species, Cabochonicus sinuosus and Minerisporites triangulatus, are described. Scanning electron microscopic examination of the spores indicates that standard palynological treatment of megaspores can result in sculptural degradation, possibly leading to incorrect generic assignment.  相似文献

The acid insoluble sclerites of Thambetolepis delicata gen. et sp. nov. of late Tommotian or immediately post-Tommotian age from near Ardrossan, South Australia, are described. These sclerites, as well as those of Sachites Meshkova 1969 and Halkieria Poulsen 1967, are from multi-sclerite animals similar to Wiwaxia Walcott 1911 together with which they constitute the new class Thambetolepidea. Biological affinities of these fossils are discussed in the light of the complex internal structure of the sclerites. Possible assignments to the opisthobranch gastropods, the polyplacophorans, or the annelids are discussed but the taxonomic position of Thambetolepis and the Thambetolepidea is unresolved.  相似文献

Abstract: Prominent assumptions about street homelessness and how it should be addressed originate primarily from middle class domiciled worldviews. This article draws on interviews with 58 street homeless people to develop a typology for explaining different forms of homelessness resulting from differences in class of origin. The concepts of social distance and abjection are used to illustrate how class politics manifests in street homelessness and in responses to this issue. Many of our homeless participants referred to two broad groupings of homeless people who display distinct experiences and cultures in their daily lives on the streets. Drifters are people who do not experience homelessness as a sharp disjuncture from their previously housed life. Street homelessness is a continuation of the hardships of their lower class backgrounds. Droppers are people who have “fallen” on hard times and aspire to return to mainstream middle class lifeworlds. Differentiating between these two groups provides a space for defamiliarizing dominant understandings of, and current generic responses to, homelessness and foregrounds the need for reorienting services to better meet the needs of drifters.  相似文献

An isolated turtle xiphiplastron similar to that of Puppigerus sp. is described from the upper Oligocene (27.3–25.2 Ma) Pomahaka Formation near Tapanui, Otago, New Zealand. The bone is unlike any previously described turtle from the Cenozoic of New Zealand and is from a newly recognized estuarine vertebrate locality. It represents the first Oligocene cheloniid turtle bone described from the southwest Pacific.

Huang, D.-Y. &; Nel, A., December, 2008. New ‘Grylloblattida’ related to the genus Prosepididontus Handlirsch, 1920 Handlirsch, A. 1920. “Kapitel 7. Palaeontologie. C.”. In Schröder Handbuch der Entomologie, III, 117304. G. Fischer, Jena.  [Google Scholar] in the Middle Jurassic of China (Insecta: Geinitziidae). Alcheringa 32, 395–403. ISSN 0311-5518.

On the basis of well-preserved nearly complete specimens, two new genera and species Sinosepididontus chifengensis and Megasepididontus grandis, both closely related to the Early Jurassic geinitziid genus Prosepididontus, are described. The new material was collected from the Middle Jurassic Jiulongshan Formation near the Daohugou Village, Ningcheng County, Inner Mongolia, northeast China. New body and leg structures are described for these Chinese taxa. They were previously unknown in other Geinitziidae. The new data indicate that the extinct ‘Grylloblattida’ contained heterogenous groups.  相似文献

Wright, A.J., Plusquellec, Y. &; Gourvennec, R., February 2016. Devonian operculate corals (Calceolidae, Cnidaria) from the Massif Armoricain, France. Alcheringa 40, xxx–xxx. ISSN 0311-5518

The operculate coral Calceola gervillei Bayle, 1878 Bayle, E., 1878. Fossiles principaux des terrains de la France. Explication de la Carte Géologique de France 4(1), 1158. [Google Scholar] is described for the first time on the basis of the type material from the Cotentin region of Normandy (North Armorican Domain), from Early Devonian (likely upper Lochkovian to lower Pragian) strata, and is chosen as the type species of the monotypic new genus Gerviphyllum. The new genus is also present in the l’Armorique Formation (lower Pragian) of the Plougastel Peninsula (Central Armorican Domain) as Gerviphyllum sp. cf. G. gervillei. One locality in the upper Emsian (Polygnathus serotinus Conodont Zone) Le Fret Formation, on the northern coast of the Crozon Peninsula, has yielded operculate coral specimens described here as ?Chakeola sp., the first (tentative) record of the genus outside eastern Australia, south China and Vietnam. The operculate coral Calceola collini sp. nov. is described from six localities in the early Middle Devonian (Eifelian: Polygnathus costatus Conodont Zone) Saint-Fiacre Formation of the Plougastel and Crozon Peninsulas (Central Armorican Domain), despite the fact that knowledge of the internal characters, especially of the operculum, of the type species Calceola sandalina is very limited. From an extensive review of published references to Calceola from France, we conclude that only the record of Collin (1929 Collin, L., 1929. Un nouveau gisement à calcéoles dans le Dévonien de la Presqu’île de Crozon (Finistère). Bulletin de la Société Géologique et Minéralogique de Bretagne 7(3/4), 201208. [Google Scholar]) is valid.

A crinoid pluricolumnal from Noil Simaam, Timor, is identified as Barycrinus? sp., the youngest member of this otherwise Mississippian genus. Identifying features of this robust specimen include a moderately broad, pentastellate lumen and pentamerism. Although likely a new species, preservation is too poor to warrant erection of a nominal taxon. The only coeval barycrinid, probably also Barycrinus?, was described from the Carnavon Basin, Western Australia.

Jarzembowski, E.A. &; Wang, B., February 2016. An unusual basal beetle from Myanmar (Coleoptera: Archostemata). Alcheringa 40, XX–XX. ISSN 0311-5518

A new archostematan beetle, Stegocoleus caii gen. et sp. nov. (Insecta: Coleoptera) is described from mid-Cretaceous Burmese amber from northern Myanmar. This is the first basal beetle to be formally described from this deposit. It shows a unique combination of family characters and is provisionally referred to Cupedidae in the broad sense and possibly subfamily Ommatinae. The dorsal ornamentation and expanded elytra with window punctures make it a very distinctive albeit rare insect in this rich amber biota. Some of the challenges in studying the inclusions in this amber deposit include their diminutive size, difficulty in preparation and deformation.

Wang, B. & Gai, Z.K., 2014. A sea scorpion claw from the Lower Devonian of China (Chelicerata: Eurypterida). Alcheringa 38, XXXX. ISSN 0311–5518.

An isolated chelicera (claw) of a pterygotid eurypterid is described from the Lower Devonian Xitun Formation of Yunnan Province, China. It is different from chelicerae of other pterygotids in having four principal denticles and at least four intermediate denticles between the principal denticles on both rami. This Chinese pterygotid, estimated at about 70 cm long, was a top predator that probably hunted small, primitive fishes, such as galeaspids. This discovery represents the first record of Pterygotidae from Asia and the third fossil eurypterid from China.
