Proterosuchid archosaur remains from the Early Triassic Bulgo Sandstone of Long Reef,New South Wales
Benjamin P. Kear 《Alcheringa: An Australasian Journal of Paleontology》2013,37(4):331-337
Two associated anterior dorsal vertebrae of a primitive archosaur are described from the Early Triassic (Dienerian–Spathian) Bulgo Sandstone at Long Reef, New South Wales, Australia. Character states including anteroposteriorly elongate centra, dorsal neural spines with height greater than length, the possible presence of intercentra, double-headed rib articulations and well-developed apical tables on the neural spines suggest affinity with proterosuchid archosauriforms and permit some comparisons with previously described Australian taxa. The Bulgo Sandstone vertebrae represent the first record of archosaurian body fossils from the Sydney Basin and are one of only a handful of occurrences thus far documented from the Triassic of Australia. 相似文献

The isolated scapula of a chelonioid sea turtle is described from the Upper Cretaceous (upper Maastrichtian) Miria Formation of the Giralia Ranges in Western Australia. Character states including the wide angle of divergence between the scapular processes (possibly reaching 140°), projection of the glenoid on a constricted scapular neck, and highly vascular glenoid articular surfaces suggest affinity with dermochelyoids—the most diverse and geographically widespread clade of Mesozoic chelonioids. The Miria Formation chelonioid scapula constitutes the first definitive record of a Late Cretaceous sea turtle from Australia and is one of the few occurrences thus far documented from Upper Cretaceous–Paleogene deposits in the Southern Hemisphere. 相似文献

Pterosaur remains are very rare in Australasia and especially in Upper Cretaceous strata. Thus, the discovery of a jaw fragment from the Cenomanian–Coniacian Molecap Greensand near Gingin in Western Australia represents an important new stratigraphical occurrence for the region. Although the teeth are not preserved, the presence of labio-lingually compressed alveoli that are anterolaterally oriented, variable in shape/size (inferring heterodonty) and very widely spaced is reminiscent of ornithocheirids—a geographically cosmopolitan clade of predominantly Early Cretaceous pterodactyloids. If correct, this identification could extend the known range of Ornithocheiridae through to the Late Cretaceous in the Southern Hemisphere. 相似文献

This paper is concerned with the technology of a small but representative sample of thirty nephrite jades from the burial assemblages of the Jin Marquisate excavated at Tianma-Qucun, Beizhao, Shanxi province, north-central China. The jades date mainly from two Bronze Age cultures, the Western Zhou dynasty (c. 1050–771 BC) and the previous Shang dynasty (c. 1600–c. 1050 BC). They include unfinished and finished carvings. The carvings were examined at Shanxi Provincial Institute of Archaeology, Houma: following an optical survey of the tool marks, detailed silicone moulds were made from twelve jades bearing evidence of working techniques. The moulds were examined by scanning electron microscopy (SEM) at the British Museum, London. Consideration of several characteristics of the moulded features for comparison with moulded experimental standards provided evidence for the tools employed for several stages of working. Extensive use was made of non-rotary rigid saws and thicker files for shaping many parts of the jades, and pointed tools for incising pieces. Use was also made of rotary solid drills for working narrow perforations for openwork and the suspension of jades, and broader tubular drills. Although no evidence of non-rotary string saws, rotary circular saws or smaller incising wheels was seen on the jades, there was evidence for the use of rotary lathes, on which jades were mounted for shaping. 相似文献

Two macropodoid endocranial casts from the early Miocene of the Riversleigh World Heritage Area, northwestern Queensland are described. The larger is associated with a fragmentary cranium and is attributable to the balbarine kangaroo Balbaroo. The smaller more complete specimen was found as an isolated endocast and cannot be confidently identified beyond superfamily level. The external neurocranial morphology of both specimens closely resembles that of plesiomorphic macropodoids and indicates a basal ‘macropodid-grade’ level of complexity. Development of the visual region of the neocortex suggests that crepuscular-nocturnal habits might have been present in early Miocene kangaroos. 相似文献

This article examines the heritage destruction undertaken by the Islamic State (IS) in Iraq and Syria. To date, their iconoclasm has been mostly characterised either as acts of wanton barbarism devoid of religious or political justification, or as a cynical performance designed as a mass media spectacle. Drawing on a systematic analysis of two key IS propaganda outlets – their on-line magazine, Dabiq, and the various slick films released by Al-Hayat – this article argues that the heritage destruction perpetrated by the IS are not only situated within a carefully articulated theological framework and key to the creation of a new and ideologically pure ‘Islamic State’, but that they are also constituted by several complex layers of religious and political iconoclasm. To demonstrate, this article documents the iconoclasm undertaken by the IS along two key axes: Symbolic Sectarianism (Shia and Sufi mosques and shrines); and Pre-Monotheistic Iconoclasm (ancient polytheistic sites). Attacks on key sites within these categories, such as the Sayyida Zaynab shrine in Damascus or the Mosul Museum, not only adhere to their religious and political framework but also serve broader geo-political agendas and are attacked as proxy targets for their physical and ideological opponents. 相似文献
