Earliest known pelecypod on Earth — a new Early Cambrian genus from South Australia

A new genus and species of fordilloid pelecypod, Pojetaia runnegari gen. et sp. nov., is described from the lower part of the Parara Limestone, Yorke Peninsula, South Australia. Establishing the age of the sample on an international scale is difficult, as with almost all Early Cambrian formations, but evidence tends to suggest that this is the oldest pelecypod so far recorded. Clearly defined hinge teeth and sockets on both valves and on internal moulds help to confirm the pelecypod placement of fordilloids.     

Qadhat—a comparative study of ancient and new lime mortar from the Marib province/Yemen

Qadhat is the name for a lime mortar in Southern Arabia. Its usage has a long tradition. This work describes physical and mineralogical properties of ancient, historical and new samples, which seem to have been produced the same way. XRD, thin sections and SEM analyses show the similarity of the material. It consists of aggregates of volcanic material that are rich in volcanic glass and lime as binder. The production process includes several hours of crushing the material, which produces fine-grained splinters of aggregates in the binder matrix and gives the mortar a high stability. A weathering test with sodium sulphate on different samples confirms that the stability of this mortar is the result of the production process.     

Taphonomy of Corumbella werneri from the Ediacaran of Brazil: sinotubulitid tube or conulariid test?

Walde, D.H.-G., Weber, B., Erdtmann, B.-D. & Steiner, M. 20 June 2019. Taphonomy of Corumbella werneri from the Ediacaran of Brazil: sinotubulitid tube or conulariid test? Alcheringa 43, 335–350. ISSN 0311-5518

The problematic late Ediacaran tubular fossil Corumbella werneri is revised based on two-dimensional compressions, and new three-dimensionally preserved specimens from the Tamengo Formation of the Corumbá Region in Mato Grosso do Sul, west-central Brazil. These fossils represent some of the oldest skeletonized metazoans and were originally described from diagenetically compacted tubes that prompted conflicting interpretations as either Ediacaran coronate scyphozoan exoskeletons, or conulariid tests. Our new material from Corumbá permits a morphological and taphonomic revision of C. werneri, which we suggest was probably a calcareous sinotubulitid. Corumbella werneri closely resembles the late Ediacaran Sinotubulites from South China, as well as the Silurian worm tube Eoalvinellodes, which has similar exterior ornamentation. Ultrastructurally, the tubes of C. werneri exhibit a coarse sparitic microtexture, which we attribute to diagenetic alteration. Partial flexibility also supports interpretation as an originally weakly calcified, or entirely organic exoskeleton. We therefore reject placement of C. werneri as a conulariid scyphozoan, and instead, advocate possible relationships with marine annelids.

Leaf galls on Dicroidium hughesii (Feistmantel) Lele from the Triassic of India—a new record

Disc-like galls are reported on the Triassic corystosperm leaf Dicroidium hughesii (Feistmantel) Lele from the Parsora Formation of South Rewa Gondwana Basin, central India. Although there have been numerous reports of arthropod–plant interactions from Permian and Lower Cretaceous successions, this is the first unequivocal report of arthropod–plant interactions from the Triassic succession of Peninsular India. The new record adds to global evidence that arthropod herbivory and gall formation, in particular, had rediversified by the Late Triassic in the wake of the end-Permian mass extinction.     

Who needs a review of the financial system in Australia? the case of the Wallis inquiry

The Howard government reoriented the then existing institutionally based financial regulation towards a functionally based regime with new prudential and disclosure regulators in 1998. This paper uses the governmental agenda-setting framework of John Kingdon to explain this financial regulatory change undertaken in Australia following the Wallis Inquiry of 1996. It also examines the role of the Inquiry in the policy process. It shows that the financial regulatory change was on the bureaucratic agenda of the Treasury Department. A window of opportunity opened for the Treasury following the 1996 election, with the new Howard government keen to achieve financial regulatory reforms to address future regulatory challenges proactively while the new Treasurer Peter Costello wanted to consolidate his power within markets and politics. Costello coupled the Treasury's solutions to problems and to political processes. The Wallis Committee was ‘packed’ by the government in accordance with its regulatory policy preferences. Its role was to legitimise the government's policy preferences publicly, and to transfer the ‘governmental agenda’ into the ‘public agenda’. However, this was not a case of the government pressuring for its policy preferences over the financial services industry. In fact, the Inquiry was used as a venue to generate industry and public support for the regulatory changes, and was used to build a network of alliances within and outside the parliament.     

A study of the origins of the Chinese communist movement from a new perspective – The History of the Establishment of the Chinese Communist Party by Ishikawa Yoshihiro

From around the time of the Opium War to the May Fourth New Culture Movement, democracy in China advanced through four stages. Originally it surfaced as a germ of rough ideas gleaned from imported knowledge; from there, democracy transpired gradually via various avenues towards a more sophisticated level in the period from the Second Opium War until before the Sino–Japanese War of 1894–1895 and meanwhile a number of individuals favoring utilitarianism opted for a constitutional monarchy as a way of making the nation strong. Then, following the Sino–Japanese War 1894–1895 until prior to the 1911 Revolution, when manifold Western ideas of democracy penetrated China, people embarked on somber discussions about what kind of democratic system China actually needed to adopt. During the years between 1912 and the May Fourth New Culture Movement, people initially rushed to build democratic politics but afterwards began to examine the ideologies and social structures that demonstrated compatibility with democracy. By the time the May Fourth Movement emerged, people hardly disagreed on the sense of democracy that they understood. After the May Fourth Movement people mainly focused their attention on the question of true and false democracy or the matter of what type of democracy harmonized best with national conditions in China.     

The northernmost South American fossil record of Boa constrictor (Boidae,Boinae) from the Plio–Pleistocene of El Breal de Orocual (Venezuela)

Onary-Alves, S.Y., Hsiou, A.S. & Rincón, A.D., July 2016. The northernmost South American fossil record of Boa constrictor (Boidae, Boinae) from the Plio–Pleistocene of El Breal de Orocual (Venezuela). Alcheringa 41, xxx–xxx. ISSN 0311-5518.

Boa constrictor is an extant boid widely distributed through the neotropical region, from the north of Central America to central Argentina. The fossil record of the species includes examples from several localities across the Americas that extend beyond the current distribution of the species. Here we report the first Plio–Pleistocene fossils of Boa from Monagas state, Venezuela. The material comes from El Breal de Orocual (Maturín municipality), which is an inactive tar seep deposit emplaced within the Mesa Formation. The specimens consist of two isolated anterior trunk vertebrae, an articulated sequence of six mid-trunk vertebrae and two posterior trunk vertebrae. The vertebrae are attributed to B. constrictor based on the following features: robust and high vertebrae; thick zygosphene with a notched or concave anterior edge; presence of a paracotylar, subcentral and lateral foramina; marked parasagittal ridges; epizygapophyseal process evident on the dorsal surface of the postzygapophyseal articular facets and high blade-like neural spine. The presence of B. constrictor in northern of Venezuela indicates a palaeoenvironment probably like savanna crossed by rivers with riparian forests, and suggests the predominance of a mesothermal climate with a moderate rainfall.

Kukulkanus,a new genus of buxtoniin brachiopod from the Artinskian–Kungurian (Early Permian) of Mexico

Torres-Martínez, M.A., Sour-Tovar, F. & Barragán, R., November 2017. Kukulkanus, a new genus of buxtoniin brachiopod from the Artinskian–Kungurian (Early Permian) of Mexico. Alcheringa 42, 268–276. ISSN 0311–5518.

Kukulkanus is the first genus of the tribe Buxtoniini recorded from rocks of the late Cisuralian (Artinskian–Kungurian). The Early Permian (Cisuralian) outcrops of the Santa Rosa Group, from southeastern Chiapas, are one of the most important marine Palaeozoic successions of Mexico. The Artinskian–Kungurian Paso Hondo Formation is the youngest unit in the succession and is dominated by massive limestone. Different marine invertebrates deposited in massive calcareous rocks characterize this formation. The buxtoniin Kukulkanus spinosus gen. et sp. nov. is reported from a single bed within the unit. The outcrops are located in southeastern Chiapas, very near the Guatemala–Mexico border. The lithological features and the preservation of fossils indicate that the fossil-bearing rocks were deposited in a low-energy open-waters paleoenvironment over the continental platform. Fusulinids, cephalopods and brachiopods previously described for the Paso Hondo Formation have been correlated with faunas of different coeval localities from Texas, New Mexico, Coahuila, Chiapas and Venezuela, regions that form part of the biotic Grandian Palaeo-Province.

Unusual belemnite — incoceramid bivalve association from the Albian (late Early Cretaceous) of Queensland,Australia

An unusual occurrence in the upper Albian Toolebuc Formation of Queensland, Australia, of penetration of a guard of the belemnite Dimitobelus (Dimitobelus) stimulus into the disc of an indeterminate inoceramid bivalve, is the first report of this type of shell damage in the fossil record. The belemnite punctured completely both valves of the bivalve to the maximum diameter of the belemnite guard, by inferred compaction from sediment overburden during post-mortem biostratinomic processes. Shell thickening of the inoceramid bivalve by shearing of prismatic layers at the site of puncture indicates that the bivalve shell behaved plastically during the puncture and that the great flexibility of the prismatic layers was facilitated by the relatively thin shell and presence of organic sheaths around individual prisms. This flexibility may have been advantageous during a predatory attack, by allowing the maintenance of a seal during breakage of the shell margin.     

Which Benjamin Franklin—Yours or mine? Examining responses to a new story from the historical archaeology site of Franklin court

Resumen La reciente revisión de las campa?as arqueológicas llevadas a cabo en la mansión de Benjamín Franklin en Filadelfia (excavada entre 1953 y 1975) revelan una nueva hístoría muy significativa para las comunidades que viven en la actualidad en Estados Unidos. La historia de Franklin, inicialmente poseedor de esclavos y posteriormente abolicionista da un giro completo cuando, en sentido figurado, los descendientes de la comunidad Afro-americana, por cuya libertad Franklin luchó, excavan la historia de Franklin para crear un lugar de culto para la memoria histórica nacional. Así mismo se ha encontrado una nueva historia relevante para los Nativos Americanos, el Movimiento de los Trabajadores, las mujeres y los colectivos de gays y lesbianas. A la luz de un contexto más amplio que engloba varias temas colectivos se analizan las diversas respuestas a estas nuevas interpretaciones.

Résumé Une récente évaluation de l'archéologie effectuée sur le site de la demeure de Benjamin Franklin à Philadelphie (déterrée 1953–1975) révèle l'interprétation d'une nouvelle histoire d'intérêt aux communautés modernes des Etats-Unis. L'histoire de Franklin, d'abord propriétaire d'esclaves puis devenu abolitioniste est révolue lorsque les descendants de la communauté afroaméricaine que Franklin s'est évertué à libérer, fouillent l'histoire de Franklin pour la création d'un monument à la mémoire nationale historique. On trouvera aussi des faits nouveaux d'intérêt pour les Américains natifs, sur le mouvement travailliste, sur les femmes et les homosexuels. On examine de nouvelles réponses sur ces sujets à la lumière des contextes plus ouverts à la base des programmes communautaires.

     

New AMS Dates from the Lambourn Long Barrow and the Question of the Earliest Neolithic in Sourthern England: Repacking the Neolithic Package?

This paper reassesses the chronological status of the Lambourn long barrow, which has provided one of the earliest dates from a mortuary monument in Britain. Three new AMS dates on short-lived material indicate that the construction and primary use phase of the monument lies within the period 3760–3645 cal BC, and that the earlier estimate obtained on charcoal (4555–3780 cal BC) is likely subject to the old wood effect, or is residual. This is followed by a consideration of the implications of the new dates in the context of the Mesolithic-Neolithic transition, the timing of which remains poorly understood. It is argued that the evidence is increasingly pointing to a more rapid neolithization process, and that this had implications for the mechanisms involved.     

Comecon and the South in the years of détente: a study on East–South economic relations

The article deals with the economic relations of the socialist bloc with less-developed countries in the 1960s and 1970s. It focuses on the economic policies envisaged by technocrats and policy-makers in the Comecon's Commission for technical assistance. It argues that the original formula based on autarky, whereby socialist aid aimed at building a clear alternative to the West and less-developed countries were advised to introduce Soviet-style planning, nationalisation and industrialisation, was progressively abandoned during détente. Doubts on the appropriateness of the Soviet model emerged, especially in Eastern European governments. Trade became increasingly crucial and the strategy of promoting an international division of labour based on mutual advantage turned into an obsession with importing strategic raw materials. In the mid-1970s, despite the official socialist view, the East pursued ‘realist’ policies that made sense in terms of economics rather than ideology. The myth of socialist modernity as a variant of industrial modernity had definitely collapsed, and socialist countries' participation in the Western-dominated world economy became a necessity. Eventually, the developing world became the place where a joint East–West co-operation could take place, often in the framework of the so-called trilateral co-operation, where Western Europe had a special role.     

Migration motives of gay men in the new acceptance era: a cohort study from Malmö, Sweden

Greater diversity in life courses has become both possible and real in the twenty-first century, affecting the relocation behaviours of individuals. Therefore, it is logical that the relocation patterns of minorities have been receiving increasing attention. In particular, the migration patterns of gay men have been studied, with a focus on the embodied reasons for mobility. This downsized analysis has shown the importance of identity building and identity search. However, this article argues that analysis of migration among gay men also needs to be upsized. This study aims to show how both context and embodiment has affected the mobility of gay men. Through a case study within the context of a strong welfare state (Sweden) that adopted sexual equality early, gay men’s motives for migration are studied. The results suggest that the migration patterns of gay men are becoming more similar to those of the general population. This finding shows that current conceptualisations of the migration patterns of gay men can be advanced by acknowledging contextual effects. The integration of a downsized and an upsized understanding also offers the possibility of moving beyond the identity specifics showing that populations are becoming increasingly diverse and homogeneous simultaneously.
