MCLOUGHLIN, S. June 2012. Nogoa nom. nov., a replacement namefor Cometia McLoughlin. Alcheringa, 279–281. ISSN 0311-5518.

A junior homonym was detected among the Rigbyaceae (Glossopteridales). The replacement name Nogoa is here proposed for Cometia McLoughlin, 1990 McLoughlin, S. 1990c. “Palaeobotany and palaeoenvironments of Permian strata, Bowen Basin”. 312Queensland: PhD thesis, University of Queensland. (unpublished) [Google Scholar] with a single included species, Nogoa biloba (McLoughlin) comb. nov.

Vandenberg, A.H.M., December 2017. Didymograptellus kremastus n. sp., a new name for the Chewtonian (mid-Floian, Lower Ordovician) graptolite D. protobifidus sensu, non. Alcheringa 42, 259–268. ISSN 0311-5518.

The ‘tuning-fork’ didymograptid previously referred to as Didymograpt(ell)us protobifidus is common in Victoria where it is confined to the Chewtonian (mid-Floian). Biometric differences indicate that the mid-Floian form is not conspecific with the holotype of the Darriwilian Didymograptus protobifidus Elles, 1933 and the Floian form is thus renamed Didymograptellus kremastus n. sp. Study of the Valhallfonna Formation faunas on Spitsbergen indicated that the Floian form of D.protobifidus’ differs from Didymograptellus bifidus (Hall) in both its morphology and stratigraphic distribution but a later study of the Cow Head Group on Newfoundland concluded that they are one species. My study, of more than 50 specimens of Didymograptellus from the Floian of Victoria, Australia, shows that the two are different and that similar differences exist in the Cow Head Group populations of Didymograptellus. The Chewtonian (Ch1) Didymograptellus protobifidus Biozone is renamed D. kremastus Biozone.

Skilliostrobus australis gen. et sp. nov. is a large, ovoid, pedunculate cone present in rocks of Early Triassic age in three areas in southeastern Australia and Tasmania. The cone is heterosporous and its unisporangiate sporophylls are wedge-shaped with long horizontal limbs. Microsporophylls occur above megasporophylls in the cone and the sporangia are adaxial. Large trilete megaspores similar to the dispersed megaspore genus Horstisporites Potonié are present in the megasporangia of the cone and the microsporangia contain small monolete spores similar to the dispersed microspore genus Aratrisporites Leschik. Skilliostrobus is placed in the family Lepidodendraceae in the order Lepidodendrales. The size of the cone suggests that the parent plant was comparable in size with small arborescent Palaeozoic lycopsids and with some species of Pleuromeia. The discovery of this cone is another indication that arborescent lycopsids did not become extinct at the end of the Paleozoic.  相似文献

Notocarpos garratti gen. et sp. nov. is described from the middle Ludlovian Humevale Formation of the Clonbinane district, Victoria. It is compared with similar anomalocystitid carpoids and is found to resemble most closely Allanicytidium flemingi Caster & Gill 1968 from the Early Devonian Reefton Beds of New Zealand. N. garratti provides evidence that anomalocystitids rested with the flattened thecal surface against the sea floor (i.e., an orientation opposite to that proposed by Jefferies, 1968). It is further suggested that the stele was adapted to provide a rearward mode of locomotion.  相似文献

Cai, C. & Huang, D., September 2016. Omma daxishanense sp. nov., a fossil representative of an extant Australian endemic genus recorded from the Late Jurassic of China (Coleoptera: Ommatidae). Alcheringa 41, xxx–xxx. ISSN 0311-5518.

Omma Newman is an extant ommatid genus currently endemic to Australia. A new Omma species, O. daxishanense sp. nov. is described and illustrated based on a compression fossil from the Upper Jurassic Tiaojishan Formation at Daxishan, a fossil locality well known for yielding mammals, feathered dinosaurs and diverse pterosaurs. Omma daxishanense is very similar morphologically to the extant O. sagitta, but differs from the latter by its broader body and prominent temples. The new discovery documents the first valid Omma species from the Mesozoic of China and highlights the antiquity and palaeodiversity of the extant Australian endemic genus.

A new species of the osmundalean fossil morphogenus Millerocaulis Tidwell emend. Vera, Millerocaulis tekelili sp. nov. is defined, based on several permineralized stems recovered from exposures of the Lower Cretaceous Cerro Negro Formation on Livingston Island, South Shetland Islands, Antarctica. This new species is characterized by the presence of an ectophloic–dictyoxylic siphonostele, inner parenchymatic and outer sclerotic cortices, heterogeneous sclerotic ring in the petiole bases, absence of sclerenchyma associated with the petiolar xylem trace, petiolar inner cortex with sclerenchyma strands and stipular wings having a large sclerenchyma bundle and several smaller ones. The presence of non-homogeneous sclerotic rings in the petiole bases allows this new species to be clearly distinguished from other Antarctic Millerocaulis, and suggests that it may represent an intermediate form in the evolutionary lineage leading from Millerocaulis to subgenus Claytosmunda of Osmunda.  相似文献

This research reviews the occurrence of animal remains in Late Neolithic and Early Bronze Age funerary contexts in three southern British counties: Wiltshire, Dorset, and Oxfordshire. Biases of survival and recovery are discussed before the data for species and body parts are analyzed. Explanations for the occurrence of animal remains are first offered in terms of chronology, monument architecture and the character of pre-existing deposits. It is then argued that animal remains (most notably deer antler) could be used to express notions of cyclical temporality and to evoke landscapes relevant to the living and the dead within the funerary context.  相似文献

Diatom and dinoflagellate cyst analysis of a 77 cm long sediment core from Cowan Creek, Hawkesbury River estuary, N.S.W., revealed changes in the catchment hydrology over the last 266 years. High abundances of the freshwater/brackish diatom genus Cyclotella at the base of the core imply sustained periods of reduced salinity that now no longer occur. Reduction of freshwater flow after approximately circa 1800 (60 cm) has allowed the development of marine planktonic diatoms Thalassiosira spp.,Ditylum brightwellii, Rhizosolenia setigera, Pseudo-nitzschia pungens and Chaetoceros spp. Benthic diatom diversity has remained relatively unchanged. The toxic dinoflagellate Gymnodinium catenatum, although identified in a cyst survey in April 1995, was not found in the sediment cores. Changes in dinoflagellate assemblage are consistent with the effects of increasing urbanisation and eutrophication.  相似文献

This paper investigates the establishment of trading regions in the global economy at the national level using a measure of trade intensity and a regional assignment algorithm that generates economically meaningful trading regions. Although there is definite regionalization in the global economy with regard to international trade, there is no evidence of an increase in the concentration of that regionalization over time. The geography of international trade is incredibly dynamic, with change related to political, historical and economic forces. Overall, trading regions have relatively few members and are increasingly a set of geographically close countries.  相似文献

Chamberlain, P.M., Travouillon, K.J., Archer, M. & Hand, S.J., November 2015. Kutjamarcoot brevirostrum gen. et sp. nov., a new short-snouted, early Miocene bandicoot (Marsupialia: Peramelemorphia) from the Kutjamarpu Local Fauna (Wipajiri Formation) in South Australia. Alcheringa 40, XX–XX. ISSN 0311-5518.

A new bandicoot species, Kutjamarcoot brevirostrum gen. et sp. nov. (Peramelemorphia), is described here from the Leaf Locality, Kutjamarpu Local Fauna (LF), Wipajiri Formation (South Australia). The age of the fossil deposit is interpreted as early Miocene on the basis of biocorrelation between multiple species in the Kutjamarpu LF and local faunas from the Riversleigh World Heritage Area (WHA). Kutjamarcoot brevirostrum is represented by isolated teeth and three partial dentaries and appears to have been short-snouted with an estimated mass of 920 g. Phylogenetic analyses place K. brevirostrum in a clade with extant Australian bandicoots and the extinct Madju, but potentially exclude the extant New Guinean bandicoots. Morphometric analysis infers close similarity between K. brevirostrum and species of Galadi in both size and rostral length. They, thus, potentially occupied compatible ecological niches with competitive exclusion perhaps explaining geographical segregation between these broadly coeval lineages.

Schmidt, R., March 2007. Australian Cenozoic Bryozoa, 2: Free-living Cheilostomata of the Eocene St. Vincent Basin, S.A., including Bonellina gen. nov. Alcheringa 31, 67-84. ISSN 0311-5518.

Free-living bryozoans are diverse in the Eocene sediments of the St. Vincent Basin, South Australia. They include Bonellina pentagonalis gen. et sp. nov., Otionellina sp. cf. O. exigua (Tenison Woods), Otionellina sp. cf. O. cupola (Tenison Woods), Tubiporella magna (Tenison Woods), Celleporaria nummularia (Tenison Woods), and an indeterminate species only found as moulds. This diversity and abundance is highest in the sediments representing the initial transgressive marine facies, where they occur in ‘sand fauna’ bryozoan assemblages (e.g. with Melicerita and Siphonicytara). Free-living bryozoans decrease up-section and are absent from latest Eocene sediments, indicating a significant environmental shift.

Yang, G., Yao, Y.Z. & Ren, D., iFirst. Poljanka strigosa, a new species of Protopsyllidiidae (Hemiptera, Sternorrhyncha) from the Middle Jurassic of China. Alcheringa, 1–6. ISSN 0311-5518.

A new fossil species, Poljanka strigosa sp. nov., of the extinct family Protopsyllidiidae is described from the Middle Jurassic Jiulongshan Formation of Daohugou Village, Inner Mongolia, China. The new species is characterized by wings bearing long, stiff setae that are evident as stained impressions in the fine sedimentary rock. Comparison between Protopsyllidiidae and extant psylloids suggests that Protopsyllidiidae is probably closely related to extant psylloids.  相似文献
