The sthenurine affinity of the Late Miocene kangaroo,Hadronomas puckridgi Woodburne (Marsupialia,Macropodidae)

Previous studies of the dentition and cranial base of Hadronomas puckridgi Woodburne suggested that this large, Late Miocene kangaroo might be related to the Sthenurinae. A recently recovered specimen, in which the neurocranium, rostrum and some of the incisors are preserved, reveals a more definite affinity with the sthenurines in its possession of laterally expanded postorbital crests of the frontals, reduced I² accompanied by enlarged I³, the presence of a well-developed posterior mental foramen, a deep, posteriorly situated digastric eminence and elevated pterygoid fossa of the dentary.     

Maradidae: a new family of vombatomorphian marsupial from the late Oligocene of Riversleigh,northwestern Queensland

Black, K., March 2007. Maradidae: a new family of vombatomorphian marsupial from the late Oligocene of Riversleigh, northwestern Queensland. Alcheringa 31, 17-32. ISSN 0311-5518.

Marada arcanum gen. et sp. nov. is described from the late Oligocene Hiatus Site, Riversleigh World Heritage Property, northwestern Queensland. Although known from only a single dentary, it is assigned to a new family Maradidae, based on a unique combination of both plesiomorphic and apomorphic features. Of the known vombatomorphians, Marada is most similar to primitive wynyardiids and diprotodontoids (palorchestids and diprotodontids). Further clarification of the phylogenetic position of Maradidae within Vombatomorphia requires discovery of upper dentitions and crania.

New methods for the identification of evidence for bitting on horse remains from archaeological sites

This article describes alterations to equid lower second premolars and diastemata from a series of known life history equids and a number of archaeological horse specimens from the British Iron Age. Two new methods for recording bit wear are proposed involving the analysis of the extent and morphology of enamel/dentine exposure on the anterior edge of LP2s and analysis of the extent of new bone formation and bone loss to the diastema of the mandible. It is suggested that when a bit is used on a horse it acts more frequently on the anterior margin of the LP2 than has previously been thought and that repeated contact between the bit and the LP2s and diastemata results in recognisable damage to these areas of the mouth.

Nothofagus leaves with plicate vernation, indicating a deciduous habit, are recorded from the Late Miocene of New Zealand. This is the first unequivocal record in New Zealand of deciduous Nothofagus, deciduous species now being restricted to Tasmania and South America.     

从曹魏都城建设与北方运河开凿看曹操的历史功绩

古代都城是古代国家的历史缩影。通过曹操父子营筑的邺城和曹魏洛阳城的考古发现与研究,以及与北魏洛阳城、隋唐长安城和洛阳城及辽金元明清都城布局形制对比,揭示出曹操所开创的都城制度对中国古代都城发展的重要影响。曹操营建的邺城,对此后中国古代政治中心东移、北移,起到了奠基性历史作用。中国古代运河是政治之河、军事之河、经济之河,是中华民族发展之河。曹操开凿的黄河以北白沟、平虏渠、泉州渠等运河,以及隋唐时代以此为基础开凿的北方隋唐大运河,极大地加强了中原与北方的联系,促进了多民族的融合,巩固了国家的统一,奠定了中古时代以后中华民族的进一步融合与全面发展,这是曹操的另一重大历史功绩。     

The first fossil sea turtles (Testudines: Cheloniidae) from the Cenozoic of Australia

An isolated dentary and costal identified as cf. Pacifichelys and Cheloniidae indet., respectively, are described from the upper Miocene–lower Pliocene Black Rock Sandstone of Beaumaris, Victoria, Australia. These remains represent the first fossil evidence of sea turtles from the Cenozoic of Australia. Neither of the fossils can be referred to living genera, indicating that extinct cheloniids occurred in southeast Australian coastal waters for at least part of the late Neogene. Thus, the taxonomic composition of the current sea turtle fauna of Australia was apparently established within the last five to six million years.     

Microflora of the middle Proterozoic Balbirini Dolomite (McArthur Group) of Australia

New genera of the Spiriferidae are described from the Permian sequences of the Carnarvon, Canning and Bonaparte Gulf Basins of Western and northwestern Australia. New taxa described are Latispirifer gen. nov. with type species Latispirifer callytharrensis sp. nov. and Latispirifer amplissimus sp. nov.; Costatispirifer gen. nov. with type species Costatispirifer gracilis sp. nov.; Cratispirifer gen. nov. with type species Cratispirifer nuraensis sp. nov. and Crassispirifer gen. nov. with type species Spirifer rostalinus Hosking (1931) and Crassispirifer pinguis sp. nov. The holotype and only extant specimen of Spirifer kimberleyensis Foord (1890) is re-examined and is assigned to Crassispirifer gen. nov. with a query.     

Migration of Mn-rich fluids through normal faults and fine-grained terrigenous sediments during early development of the Neogene Vallès-Penedès half-graben (NE Spain)

The Miocene siliciclastic sediments infilling the Vallès‐Penedès half‐graben are affected by two sets of structures developed during the extensional tectonics that created the basin. The first set, represented by extension fractures infilled with mud and sands, is attributed to seismically induced liquefaction. The second set, represented by normal faults, corresponds to a high‐permeability horsetail extensional fracture mesh developed near the surface in the hanging walls of normal faults. The incremental character of the vein‐fills indicates episodic changes in the tectonic stress state and fault zone permeability. Two episodes of fluid migration are recorded. The first episode occurred prior to consolidation and lithification when shallow burial conditions allowed oxidizing meteoric waters to flow horizontally through the more porous and permeable sandy layers. Development of clastic dikes allowed local upward flow and dewatering of the sandy beds. Liquefaction and expulsion of fluids were probably driven by seismic shaking. During the first episode of fluid migration there was no cementation of the sandstone or within the fractures, probably because little fluid was mobilized by the predominantly compaction‐driven flow regime. The second episode of fluid migration occurred synchronously with normal fault development, during which time the faults acted as fluid conduits. Fluids enriched in manganese, probably leached from local manganese oxyhydroxides soon after sedimentation, moved laterally and produced cementation in the sandstone layers, eventually arriving at the more porous and permeable fault pathways that connected compartments of different porosities and permeabilities. Carbonate probably precipitated in fractures saturated with meteoric water near the ground surface at a transitional redox potential. Once the faults became occluded by calcite cement, shortly after fault development, they became barriers to both vertical and horizontal fluid flow.     

Roman Navigation in Venice Lagoon: the Results of Underwater Research

Venice lagoon formed part of a network of inland waterways used for navigation in the northern Adriatic, an almost continuous system of lakes, river‐mouths and canals, at least partly pre‐Roman in origin. The fossae which cross the present lagoon are the continuation of a complex system of natural watercourses and artificial canals between Ravenna and Aquileia. Two Roman buildings discovered on the present San Felice canal could be interpreted as providing navigational assistance at points linking the sea and inland routes. © 2009 The Authors     

Gazella (Bovidae,Ruminantia) remains from the Siwalik Group of Pakistan

Khan, M.A., Babar, M.A., Akhtar, M., Iliopoulos, G., Rakha, A. & Noor, T., November 2015. Gazella (Bovidae, Ruminantia) remains from the Siwalik Group of Pakistan. Alcheringa 40, xxx–xxx. ISSN 0311-5518.

New gazelle fossils are described from the Siwalik Group of Pakistan. The material includes horncores, maxilla and mandible fragments, and isolated teeth. The available samples are assigned to three Gazella species: Gazella sp. in the Lower Siwalik Subgroup (ca 14.2–11.2 Ma), and G. lydekkeri and G. superba in the Middle Siwalik Subgroup (ca 10.2–3.4 Ma). Based on a review of the Siwalik Group gazelles, G. padriensis is synonymized with G. lydekkeri. Gazella superba Pilgrim, 1939 sensu stricto is a large form and is a valid species of the genus in the Siwalik Group.

Fruits and leaves with cuticle of Laurelia otagoensis sp. nov. (Atherospermataceae) from the early Miocene of Otago (New Zealand)

Conran, J.G., Bannister, J.M. & Lee, D.E., 2013. Fruits and leaves with cuticle of Laurelia otagoensis sp. nov. (Atherospermataceae) from the early Miocene of Otago (New Zealand). Alcheringa 37, 496–509. ISSN 0311-5518.

Laurelia otagoensis sp. nov. Conran, Bannister & D.E. Lee (Laurales: Atherospermataceae) is described from the earliest Miocene Foulden Maar diatomite deposit, Otago, New Zealand. The new species is represented by mummified fossil leaves with well-preserved cuticle and associated clusters of achenes bearing persistent, long plumose styles. This basal angiosperm family is of significance because of its classic southern disjunctions and ecological importance in extant Gondwana-type rainforests, but has a very sparse fossil record. The present study describes one of very few convincing leaf fossils for Atherospermataceae and the only definitive fossil fruits. The presence of fossil Laurelia in Oligo–Miocene New Zealand combined with fossil leaf impressions from the late Eocene, Miocene dispersed cuticle and pollen from the Oligocene to Holocene shows that the family has had a long history in Cenozoic New Zealand. These new fossils also support palaeoclimatic data suggesting warmer conditions in the earliest Miocene of New Zealand.

The Earls of Thanet and the Industrialisation of the Valley of Eller Beck at Skipton,North Yorkshire

The wooded valley of Eller Beck at Skipton in North Yorkshire became the focus for the early industrialisation of the town during the 18th century, as the Earls of Thanet pursued improvement of their estates. Initially, investment was directed towards the quarrying of limestone and its export via the Springs Canal. The quarrying interest had shifted further east to Haw Bank by 1785, and a network of dams and watercourses was then constructed to power a new cotton mill. The canal was extended concurrently, and a railway from Haw Bank to a new canal terminus was constructed, transforming the historic landscape in the valley beneath the north walls of Skipton Castle. Downstream from the cotton mill, enterprising new industry was established at the former manorial corn and fulling mills. Recreational use of the woodland has since become a significant component within the regional tourist economy, thereby initiating a discrete new industrial phase.

A new antiarch placoderm from the Emsian (Early Devonian) of Wuding,Yunnan, China

Pan, Z., Zhu, M., Zhu, Y. &; Jia, L., August 2017. A new antiarch placoderm from the Emsian (Early Devonian) of Wuding, Yunnan, China. Alcheringa 42, 10–21. ISSN 0311-5518.

Wufengshania magniforaminis, a new genus and species of the Euantiarcha (Placodermi: Antiarcha), is described from the late Emsian (Early Devonian) of Wuding, Yunnan, southwestern China. The referred specimens were three-dimensionally preserved in black shales, allowing a high-resolution computed tomography reconstruction of anatomical details. The new euantiarch is characterized by a large orbital fenestra, an arched exoskeletal band around the orbital fenestra and a developed obtected nuchal area of the skull roof. Maximum parsimony analysis, using a revised data-set of antiarchs with 44 taxa and 66 characters, resolves Wufengshania gen. nov. as a member of the Bothriolepididae, which is characterized by the presence of the infraorbital sensory canal diverging on the lateral plate, and the nuchal plate with orbital facets. New analysis supports a sister group relationship between Dianolepis and the Bothriolepididae. Luquanolepis, a coeval euantiarch from the neighboring site of the new form, is referred to the Asterolepidoidei and represents the basalmost and earliest member of the Asterolepidoidei.

Humeral morphology of the early Eocene mekosuchine crocodylian Kambara from the Tingamarra Local Fauna southeastern Queensland,Australia

Stein, M., Salisbury, S.W., Hand, S.J., Archer, M. & Godthelp, H., December 2012. Humeral morphology of the early Eocene mekosuchine crocodylian Kambara from the Tingamarra Local Fauna southeastern Queensland, Australia. Alcheringa 36, 473–486. ISSN 0311-5518.

Mekosuchines (Crocodylia; Crocodyloidea) were a clade of crocodylians endemic to Australia and the South Pacific that underwent radiation during the Cenozoic. Numerous questions about mekosuchine palaeoecology remain unanswered. Tantalizing among these is the possibility that some mekosuchines were primarily terrestrial. To date, studies of mekosuchines have focused mainly on the cranium. However, the morphological signal for terrestriality is more likely to be found in the postcranial skeleton. Here, we present a comparative morphological study of fossil humeri referable to Kambara from the early Eocene Tingamara Local Fauna, Murgon, southeastern Queensland. The humeri of Kambara do not show the torsion between the proximal and distal extremity seen in extant crocodylians, illustrated here with Crocodylus porosus and Crocodylus johnstoni. They also differ in the structure of the medial and lateral condyles of the distal extremity. When the effects of these features on musculature and articulation are considered, it appears that the forelimb of Kambara could have facilitated a greater force at the glenohumeral joint and possibly swung the lower forelimb faster with a greater arc of motion than Australia's extant crocodylians. This is conducive to an improved capacity for both terrestrial locomotion and paraxial swimming. Although the former case suggests that Kambara may not have been as closely tied to water as extant crocodylians, it is unusual given the typically broad rostra of the cranium. Among crocodylians this is a common characteristic of semi-aquatic ambush predators. This study shows the utility of the postcranial skeleton in interpreting crocodylian palaeoecology.

An interdisciplinary approach to the understanding of past settlement and farming: two cases from SE Norway

An interdisciplinary approach involving analysis of plant macrofossils, pollen and soil micro morphology in combination with large-scale stripping of top soil, was applied in order to get a comprehensive understanding of pre-historic settlement, farming economy and land-use in Østfold, SE Norway. Investigations of 25 sites lead to two distinctive results: 1) A time-space perspective on usages of plants, and 2) Identification of agrarian activities in a relict field. Studies of these topics have hitherto been limited for this region. The results add fresh and essential knowledge to pre-historic times in Østfold and make a significant contribution to the understanding to these topics in neighbouring regions.
