Cook, A.G. &; Jell, P.A., September 2015. Carboniferous platyceratid gastropods from Western Australia and a possible alternative lifestyle adaptation. Alcheringa 40, XX–XX. ISSN 0311-5518

Platyceratid gastropods, common and in many cases abundant as elements of middle Palaeozoic gastropod faunas worldwide, are rare or absent in Australian Devonian faunas. In Australia, the earliest abundant platyceratids occur in the Lower Carboniferous (Tournaisian) echinoderm-rich Septimus Limestone and Enga Sandstone in the Bonaparte Gulf Basin, Western Australia. Four taxa, each with significant morphological plasticity, are recognized. In Platyceras (Platyceras) tubulosus (de Koninck, 1883 Koninck, L.G. De, 1883. Faune du calcaire Carbonifère de La Belgique, Quatrième Partie, Gastropodes (suite et fin). Annales du Musée Royal D’Histoire Naturelle de Belgique Tome VIII, Text, 1240, pls 1–54. [Google Scholar]), three rows of long radially arranged spines and common pentameral symmetry of re-entrants on the aperture suggest an alternative possibility that a relationship between echinoderms and platyceratids developed, and that this may be with archaeocidaroids that are commonly preserved with the gastropods. Similarly in the singly spinose Platyceras (Platyceras) emmemmjae sp. nov., re-entrants suggest an echinoderm relationship. It is proposed that an echinoderm–Platyceras relationship possibly developed in Australia only after a suitable echinoid host had evolved allowing an alternative way for a gameto- or coprophagous habit to be exploited fully.

O’Gorman, J.P., Otero, R.A. & Hiller, N., 2014. A new record of an aristonectine elasmosaurid (Sauropterygia, Plesiosauria) from the Upper Cretaceous of New Zealand: implications for the Mauisaurus haasti Hector, 1874 Hector, J., 1874. On the fossil Reptilia of New Zealand. Transactions and Proceedings of the New Zealand Institute 6, 333358. [Google Scholar] hypodigm. Alcheringa 38, 504–512. ISSN 0311-5518

An indeterminate aristonectine elasmosaurid is recorded from a lower Maastrichtian bed of the Conway Formation, Waipara River, South Island, New Zealand. The described specimen (CM Zfr 104), previously considered part of the hypodigm of Mauisaurus haasti, came from the upper part of the Alterbidinium acutulum biozone, the same zone from which the only well-known aristonectine from New Zealand, Kaiwhekea katiki, is recorded. The cervical vertebrae of CM Zfr 104 have the same distinctive features (i.e., with extremely broad rather than long centra) as those from previously recorded juvenile aristonectines from Argentina, Chile and Antarctica. This new record is congruent with the biogeographic relationships of Cretaceous marine amniotes from the Weddellian Palaeobiogeographic Province (i.e., Patagonia, western Antarctica, New Zealand and southeastern Australia). Therefore, this type of vertebra is regarded as a distinctive feature of the Weddellian aristonectine elasmosaurids.

Some popular texts have associated airports with a lack of identity. It is supposed that people are alienated from these ahistorical and interstitial spaces (Augé 1995 Augé, M. 1995. Non-places: Introduction to an Anthropology of Supermodernity, London: Verso.  [Google Scholar]; Castells 1996 Castells, M. 1996. The Rise of the Network Society, Volume 1: The Information Age: Economy, Society and Culture, Oxford: Blackwell.  [Google Scholar]). Other approaches have tended to ignore their sociality, exploring their role within transport networks rather than what goes on within. Through a discussion of the early beginnings of British airport development and the construction of Liverpool Airport at Speke, I attempt to show how there are other contextual geographies to airports. By using the concept of air-mindedness—a moral geographical concept that promoted the belief in the possibilities of aircraft mobility, this paper discusses how social identities became bound to flight, forming the context to the development of the airport and both local and national belonging. This examination will reveal the embeddedness of airports within the times, spaces and uses from which they are produced and consumed. Archival research provides the material for this discussion.

Les aéroports et le sens des choses de l'air: l'espace, le temps et l'utilisation de l'aéroport de Liverpool, 1929–1939

Un nombre d'écrits populaires ont dressé un parallèle entre les aéroports et un déficit d'identité. Les gens, suppose t'on, se sentent aliénés par ces espaces ahistoriques et interstitiels (Augé 1995 Augé, M. 1995. Non-places: Introduction to an Anthropology of Supermodernity, London: Verso.  [Google Scholar]; Castells 1996 Castells, M. 1996. The Rise of the Network Society, Volume 1: The Information Age: Economy, Society and Culture, Oxford: Blackwell.  [Google Scholar]). Dans d'autres cas, on a fait fi de leur socialité, explorant alors leur rôle au sein de réseaux des transports plutôt que de s'intéresser à ce qui se passe dedans. Une discussion sur les tout débuts de l'expansion des aéroports britanniques et de la construction de l'aéroport de Liverpool à Steke tente de montrer comment les aéroports sont situés dans des contextes géographiques différents. Grâce au concept du sens des choses de l'air—un concept moral en géographie qui renforçait la croyance dans les possibilités de mobilité qu'offre l'avion, cet article traite de la façon dont les identités sociales se rattachent au vol créant ainsi le contexte dans lequel se situe le développement de l'aéroport et de l'appartenance locale et nationale. Dans cette étude, il est question de l'enchâssement des aéroports dans les époques, espaces et usages à partir desquels ils sont produits et consommés. La discussion fait état des résultats d'une recherche en archivistique.

Aeropuertos y air-mindedness: espacio, tiempo y el uso del aeropuerto de Liverpool 1929–1939

Algunos textos populares asocian los aeropuertos con una falta de identidad. Se supone que la gente se siente distanciada de estos espacios ahistóricos e intersticiales (Augé 1995 Augé, M. 1995.

Los enfoques de otros no tienen en cuenta el aspecto social y exploran el papel del aeropuerto en las redes de transporte en vez de explorar lo que pasa dentro del mismo aeropuerto. Por un estudio de los inicios del desarrollo del Aeropuerto Británico y la construcción del aeropuerto de Liverpool en Speke, pretendo mostrar que, con respecto a los aeropuertos, hay otras geografías contextuales para explorar. Haciendo uso de la idea de ‘air-mindedness’—un concepto geográfico moral que fomentaba confianza en las posibilidades de movilidad aeronáutica—este papel habla de cómo las identidades sociales llegaron a ser vinculadas a la aviación, así formando el contexto para el desarrollo del aeropuerto y un sentido de pertenencia, tanto local como nacional. Este estudio revela hasta qué punto los aeropuertos se han arraigado en los tiempos, espacios y usos de los cuales son producidos y consumidos. Hago uso de investigaciones de archivos para este debate.

A new genus, Sinitshenkovae gen. nov., is described, comprising the Carboniferous species Sinitshenkovae hueneckeni (Pinto & Pinto de Ornellas, 1978 Pinto, I.D. & Pinto de Ornellas, L., 1978. Upper Carboniferous insects from Argentina. 1. Familia Diaphanopteridae (Megasecopteroidea). Pesquisas (Zoologiat) 10, 8795. [Google Scholar]) comb. nov. from South America and new Guadalupian species S. gallica sp. nov. from France. These two species are attributed to the Paleozoic South American family Xenopteraidae, a previously monospecific family only containing Xenoptera riojaensis Pinto, 1986 Pinto, I.D., 1986. Carboniferous insects from Argentina. 3. Family Xenopteridae Pinto nov. fam. (Megasecoptera). Pesquisas (Zoologia) 18, 2329. [Google Scholar]. Sinitshenkovae gallica sp. nov. is therefore the youngest representative of this family and the only record outside South America, which suggests that our current knowledge of the palaeobiogeography of Permian and Carboniferous insects remains incomplete.

Tineo, D.E., Bona, P., Pérez, L.M., Vergani, G.D., González, G., Poiré, D.G., Gasparini, Z.N. & Legarreta, P., 1.10.2014. Palaeoenvironmental implications of the giant crocodylian Mourasuchus (Alligatoridae, Caimaninae) in the Yecua Formation (late Miocene) of Bolivia. Alcheringa 39, xxx–xxx. ISSN 0311-5518

Outcrops of the Yecua Formation (late Miocene) are exposed for approximately 230 m along the La Angostura section of the Piraí River (50 km southwest of Santa Cruz de la Sierra). These reveal massive (argillic palaeosols) and laminated (quiet-water lacustrine and marsh settings) mudstones interbedded with thin sandstones containing microfossils, molluscs and vertebrate remains. Significantly, the succession hosts a giant crocodylian, Mourasuchus (Alligatoridae, Caimaninae), which is represented by both skull and postcranial fragments found in association with freshwater turtles and fishes. Mourasuchus was distributed widely from the middle Miocene of Colombia to upper Miocene of Venezuela, Brazil and Argentina, suggesting connections between major fluvial systems and an active mechanism for dispersal of South American freshwater vertebrates during the Miocene.

(in Spanish) [Google Scholar]) fossil leaves collection, Alcheringa 42, 125–153. ISSN 0311-5518.

The Río Turbio Formation (Eocene–?Oligocene) is of particular paleobotanical interest owing to its combination of high fossil plant diversity associated with the coexistence of warm-temperate and cool-temperate components. As the first suite of fossils related to a documented stratigraphic section, Hünicken’s fossil plant collection is one of the most important from the Paleogene of South America. A total of 34 angiosperm species from the collection were reviewed and taxonomically updated, with Nothofagus as the dominant genus. The taxa identified indicate a warm and humid climate with the development of some elements of a cool-temperate climate marked by a transitional climate change to cooler conditions. The comparison of angiosperms from different paleofloras from the southernmost of South America confirms that the assemblage of Río Turbio Formation was similar to that of the Río Pichileufú area, both from Patagonia, Argentina.

In this article, I am concerned with the importance of knowledge spaces to the construction and politics of scale. I draw together literatures on re-scaling with feminist critiques of knowledge to show how struggles over the scale at which knowledge claims are represented and legitimized are an important, and under-recognized, element of rescaling. I draw from Neil Smith's (1984) concept of scale-jumping to see the construction of the global space of knowledge as a scale-jump in which one particular situated knowledge, Western folk belief, is redefined as global and universal. What distinguishes it from other forms of local/anecdotal/unrecognizable knowledges is its relation to power and its capacity to achieve a scale-jump in which it is defined as global knowledge. I contrast the social, economic and power relations associated with knowledge in the village of Puno in the Philippines with those of technoscientific knowledge, as manifested by regimes of intellectual property, to show that knowledges are not a natural way of understanding a separate, pre-existing world but inform how that world is experienced. I build upon David Turnbull's (1997) concept of knowledge spaces to reveal all knowledges as not only arising from a particular context but also as creating that context.

Connaître l'échelle: les droits relatifs à la propriété intellectuelle, les espaces de savoir et la production du mondial

Dans cet article, je me penche sur l'importance des espaces de savoir dans la construction et les politiques d'échelle. Je marrie les corpus sur les transformations d'échelle et les critiques féministes du savoir pour montrer comment les débats qui entourent l'échelle à partir de laquelle les prétentions au savoir sont représentées et admises comme légitimes sont une dimension importante et peu connue des transformations d'échelle. Le concept de saut d'échelle proposé par Neil Smith (1984 Smith, N. 1984. Uneven Development, Oxford: Basil Blackwell.  [Google Scholar]) me sert de point d'appui pour mieux situer la construction d'un espace mondial du savoir en tant que saut d'échelle par lequel un savoir contextualisé, en l'occurrence les croyances folkloriques occidentales, est redéfini en fonction du mondial et de l'universel. Ce savoir se démarque des autres formes de connaissances locales/anecdotiques/indiscernables par son rapport au pouvoir et par sa capacité d'opérer un saut d'échelle vers un savoir mondial. Je compare les relations sociales, économiques et de pouvoir liées au savoir dans le village de Puno aux Philippines avec celles qui relèvent du savoir technoscientifique, telle qu'elles se manifestent dans des régimes de propriété intellectuelle, pour montrer que ces connaissances ne sont pas un moyen naturel de comprendre un monde distinct et préexistant, mais représentent plutôt une source d'informations sur la manière dont le monde est connu. Je prolonge le concept des espaces de savoir de David Turnbull (1997 Turnbull, D. 1997. Reframing science and other local knowledge traditions. Futures, 29: 551563. [Crossref], [Web of Science ®] [Google Scholar]) afin de démontrer que toutes les connaissances proviennent non seulement d'un contexte en particulier, mais qu'elles peuvent également créer ce contexte.

Sabiendo escala: derechos de propiedad intelectual, espacios de conocimiento y la producción de lo mundial

En este artículo trato la importancia de espacios de conocimiento con relación a la construcción y la política de escala. He unido literatura sobre el reescalar con críticas feministas sobre conocimiento para ilustrar como la lucha sobre la escala a que se representa y legitima los conocimientos es un elemento del reescalar importante y poco reconocido. Hago uso del concepto de Neil Smith (1984 Smith, N. 1984. Uneven Development, Oxford: Basil Blackwell.  [Google Scholar]) de saltar escalas para ver la construcción del espacio mundial de conocimiento como un salto de escala en que un conocimiento particular, la creencia folklórica occidental, se redefine como mundial y universal. Lo que le diferencia de otras formas de conocimiento locales/anecdóticas/irreconocibles es su relación al poder y su capacidad de saltar de una escala para otra, así redefiniéndose como conocimiento mundial. Comparo las relaciones sociales y económicas y relaciones de poder asociadas con conocimiento en el pueblo de Puno en las Filipinas con las relaciones de conocimiento tecnocientíficas, tal como son manifestados por regimenes de propiedad intelectual para ilustrar que los conocimientos no representan una manera natural de entender un mundo separado que ya existía, sino que informan la manera en que se experimenta ese mundo. Amplio el concepto de espacios de conocimiento de David Turnbull (1997 Turnbull, D. 1997. Reframing science and other local knowledge traditions. Futures, 29: 551563. [Crossref], [Web of Science ®] [Google Scholar]) para revelar que todos los conocimientos no sólo surgen de un contexto paricular, sino que también crean ese contexto.  相似文献

The first fossil representative of the extant chironomid genus Nandeva Wiedenbrug, Reiss &; Fittkau, 1998 Wiedenbrug, S., Reiss, F. &; Fittkau, E.J., 1998. Nandeva, gen. nov., a new genus of Chironomini (Insecta, Diptera, Chironomidae). Spixiana 21, 5968. [Google Scholar] is described based on a specimen found in early Eocene (50–53 Ma) Fushun amber from China. The adult male of Nandeva pudens sp. nov. has the long RM vein as a continuation of M and R4+5, the bare squama, the strongly reduced anal area of the wing and hypopygial characters typical of extant species of the genus. Following the systematic concept based on adult male morphology and characters examinable in fossil specimens, we present N. pudens as a possible member of the Tanytarsini, arguing that Nandeva is part of this tribe or a possible sister group to the tribe. This is the first record of Nandeva from the Palaearctic region.

A review of Monostychia, a stratigraphically important clypeasteroid echinoid genus in southern Australian Oligocene/Miocene strata, reveals uncertainty in relation to morphological features used in taxonomy. The result is that the exact systematic position of the genus remains unresolved at subfamily level. Monostychia and its type species, M. australis, are redescribed. Monostychia australis is restricted to the lower to middle Miocene Glenforslan Formation of the Murray Basin. Three other species currently within Monostychia, M. etheridgei, M. loveni and M. elongata, are discussed. Although it is concluded that M. etheridgei belongs in the genus and is a distinct species, the taxonomic position of M. loveni is questioned, and the validity of M. elongata as a separate species from M. australis remains uncertain. This work lays the foundation for further revisions of Monostychia with an expectation that such work will provide the basis for character determination that may be useful across other echinoid taxa.

Gordillo, S., 2013. Muricid boreholes in Pleistocene acorn barnacles from the Beagle Channel: trophic interactions during the Last Interglacial in southern South America. Alcheringa 37, 1–8. ISSN 0311-5518.

Acorn barnacles with boreholes were recovered from a Pleistocene marine deposit on Navarino Island, on the southern coast of the Beagle Channel. Balanomorph shells were identified as Balanus laevis (Bruguière, 1789 Bruguière, J.G., 1789. Encyclopédie méthodique. Histoire naturelle des vers 1, 158–173, pis.

If so, this study is the first record of drilling predation on fossil barnacles reported in southern South America.

LUO, M. &; SHI G.R., February 2017. First record of the trace fossil Protovirgularia from the Middle Permian of southeastern Gondwana (southern Sydney Basin, Australia). Alcheringa 0, 000–000. ISSN 0311-5518.

This study reports the first examples of well-preserved chevronate trails referable to Protovirgularia longespicata De Stefani, 1885 Stefani, DE.C., 1885. Studi paleozoologici sulle creta superiore e media dell' Apennino settentionale. Atti della Reale Accademia dea Lincei, Memorie 22, 101?134. [Google Scholar] from the early Middle Permian (Roadian) upper Wandrawandian Siltstone of the southern Sydney Basin, southeastern Australia. The highly meandering trace with closely spaced, papillate chevrons is interpreted to have been produced by the locomotion-feeding behaviour of certain protobranch bivalves in an offshore environment. The dense trails occurring on the upper bedding planes of pebbly siltstone may represent a gregarious lifestyle, where junior and senior individuals of the trace-maker bivalves coexisted while moving within sediments. The Wandrawandian Protovirgularia also represents the first known occurrence of this ichnotaxon from a glaciomarine environment in the Permian eastern Gondwana. The global record of Protovirgularia occurrences suggests that these trails had a wide environmental distribution since the Cambrian, and there is no obvious difference in the environmental distribution of Protovirgularia after the Permian?Triassic transition.

Mackness, B.S., Black, K.H. & Price, G.J., 1.10.2014. Occurrence of Euowenia grata (De Vis, 1887 De Vis, C.W. [In Anon.] 1887. Untitled. The Brisbane Courier 9224 (44) (8 August), 6. [Google Scholar]) (Diprotodontidae, Marsupialia) from the Pliocene Spring Park Local Fauna, northeastern Queensland. Alcheringa 39, 000?000. ISSN 0311-5518

Ten specimens including several dentaries and maxillae, recovered from the Pliocene Spring Park Local Fauna, northern Australia, are referred to the diprotodontine Euowenia grata (De Vis). The fossils exhibit minimal dental wear and reveal new characters that are unrecognizable in the holotype. The remains represent at least three animals, effectively doubling the previous number of individuals known for this rare megaherbivore. The new records also provide a significant northern geographic range extension for the species and allow an assessment of intraspecific variation, sexual dimorphism and phylogenetic relationships for the species. Euowenia grata is most similar in morphology to the monotypic Pliocene diprotodontid Meniscolophus mawsoni.

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 species of Kalligramma Walther, 1904 Walther, J., 1904. Die Fauna der Solnhofener Plattenkalke bionomisch betrachtet. Denkschriften der Medizinisch-Naturwissenschaftlichen Gesellschaft zu Jena 11, 133214. [Google Scholar] (Insecta, Neuroptera, Kalligrammatidae) is described as Kalligramma delicatum based on a nearly complete forewing from the Middle–Upper Jurassic of Daohugou, Inner Mongolia, China. The new species is characterized by the narrow costal space with sinuous costal veinlets, Rs with eight primary branches, MP with five pectinate branches and 1A forked beyond its mid-length. The forewing of Kalligramma can be distinguished from the hind wing by its ovate rather than subtriangular shape, significantly wider costal space and more numerous crossveins between costal veinlets. The new species is interpreted to represent a forewing based mainly on its shape.
