Abstract Advances in dating and systematics have prompted a revision of monotreme evolution to refine the timing of adaptative trends affecting body size and craniodental morphology. The oldest known monotreme, Teinolophos trusleri, is restricted to uppermost Barremian deposits of the Strzelecki Group in Victoria, Australia. Its body mass is estimated at ∼40 g, making it the smallest known monotreme. Teinolophos trusleri likely possessed an electro-sensitive and/or mechano-sensitive ‘bill’ or ‘beak’, which we suggest evolved for insectivory in seasonally dark Early Cretaceous polar forests. During the early Albian–mid-Cenomanian, monotremes diversified in Australia and evolved body masses greater than 4 kg, becoming amongst the largest Mesozoic mammals. A gap of 35 million years subsequently separates the youngest Mesozoic monotremes from the oldest Cenozoic monotreme, Monotrematum sudamericanum, which is a Paleocene stem ornithorhynchid from southern South America. We also hypothesize that tachyglossids originated in Melanesia, perhaps on the emergent Vogelkop landmass, and then dispersed to Australia during the Pliocene-Pleistocene. Finally, we present a classification of Monotremata to include five families—Teinolophidae fam. nov., Kollikodontidae, Steropodontidae, Ornithorhynchidae, and Tachyglossidae. We also propose a new genus, Murrayglossus gen. nov. for a gigantic Pleistocene echidna from southwestern Western Australia. http://zoobank.org/urn:lsid:zoobank.org:pub:E39E2644-DADD-49F4-B2B7-47A25C072B07 Timothy F.

在年代和分类学方面的进展促使对单目动物进化的修正，以确定影响体型和颅齿形态的适应趋势的时间。已知最古老的单目动物，Teinolophos trusleri，仅限于澳大利亚维多利亚州Strzelecki Group最上层的Barremian矿床。它的体重估计在40克左右，是已知最小的单目动物。Teinolophos trusleri可能拥有对电敏感和/或机械敏感的“喙”或“喙”，我们认为这是为了在白垩纪早期季节性黑暗的极地森林中进化而来的。在早期的阿尔及利亚和中期的诺曼尼亚，单孔目动物在澳大利亚多样化，并进化出超过4公斤的体重，成为中生代最大的哺乳动物之一。随后，一个3500万年的间隙将最年轻的中生代单目动物与最古老的新生代单目动物Monotrematum sudamericanum分开，这是一种来自南美洲南部的古新世干鸟喉目动物。我们还假设速舌化石起源于美拉尼西亚，可能是在新兴的Vogelkop大陆上，然后在上新世-更新世期间分散到澳大利亚。最后，我们提出了单吸虫的分类，包括五个科- teinolophidae fam。11、Kollikodontidae、Steropodontidae、Ornithorhynchidae、Tachyglossidae。我们还为西澳大利亚西南部的一种巨大的更新世针鼹提出了一个新属，Murrayglossus gen. 11。http://zoobank.org/urn:lsid:zoobank.org:pub:E39E2644-DADD-49F4-B2B7-47A25C072B07 Timothy F.

Abstract The Protopsyllidiidae are an extinct group of plant-sucking hemipterans that were distributed worldwide. However, Jurassic and Cretaceous taxa have only been reported from the Northern Hemisphere. Here we describe and illustrate a new protopsylliidid, Talbragaropsyllidium averyi gen. et sp. nov., based on 11 well-preserved specimens from the Upper Jurassic Talbragar Fish Bed of New South Wales, Australia. These specimens represent the first Jurassic protopsyllidiid documented from both the Southern Hemisphere and Gondwana, which significantly extends the distributional and stratigraphical range of the family.

Photography using cross-polarized light is a standard technique for certain types of fossils such as Burgess Shale material; however, the technique has not been used for photography of graptolites. Here we demonstrate that cross-polarized illumination is useful for obtaining high-quality images of graptolites. The technique can also facilitate visualization of fusellar banding, allowing fossils of uncertain affinity to be identified as graptolites.

Abstract The fossil record of scorpions in Australia is effectively non-existent. This lack of data is striking as there is evidence for other euchelicerates including eurypterids, spiders, and xiphosurids. Here, we describe a euarthropod from the Middle Triassic Hawkesbury Sandstone of Sydney, New South Wales, and attribute it to the Order Scorpiones. Due to lack of other diagnostic features, we are unable to assign the specimen to a higher-order classification. Nonetheless, this discovery confirms that scorpions were present in Australia since at least the mid-Triassic. Russell D. C.

澳大利亚的蝎子化石记录实际上是不存在的。这种数据的缺乏令人震惊，因为有证据表明其他的准螯足类动物包括泛足类、蜘蛛和剑足类。本文描述了新南威尔士州悉尼中三叠世Hawkesbury砂岩中的一种真节肢动物，并将其归类为蝎目。由于缺乏其他诊断特征，我们无法将标本分配到高阶分类。尽管如此，这一发现证实了蝎子至少在三叠纪中期就出现在澳大利亚了。Russell d.c.

Abstract A new extinct bethylid wasp attributable to the subfamily Scleroderminae is described from upper Eocene amber found at the Voronki mine in the Vladimirets District of the northwestern Rovno region, western Ukraine. The distribution of Scleroderminae in tropical and temperate regions is discussed. Three species of Bethylinae, seven species of Epyrinae, and three Pristocerinae have already been described from the same amber-bearing deposits demonstrating the rich diversity of Eocene Bethylidae.

Abstract After the Late Ordovician mass extinction, brachiopods recovered and re-radiated during the Aeronian age of the early Silurian. However, a drastic turnover of Ordovician-type to Silurian-type faunas took place. In South China, Aeronian brachiopod faunas are rarely reported and typically of low diversity. Here, we describe an endemic brachiopod faunule from the middle Xiangshuyuan Formation (middle Aeronian) of Yinjiang in northern Guizhou Province, South China. The fossils include five endemic species assigned to five genera. With the exception of Zygospiraella, at least three of these genera are also endemic. The diagnoses of Qianomena and Sinokulumbella are revised based on new specimens. The palaeobiogeographical and palaeoecological implications of the faunule are discussed and interpreted as products of climatic warming and increased habitat heterogeneity during the Aeronian.

Abstract A single tetrapod tooth has been recovered from the Upper Jurassic Talbragar Fossil Fish Bed of New South Wales, Australia. It is the first evidence of a tetrapod to have been found at this locality in over 130 years of excavation. The tooth is likely from a temnospondyl amphibian. Herein, we document the discovery, discuss the potential explanations as to why tetrapod remains are so scarce from this locality and provide hypotheses as to how this tooth came to be preserved.

摘要在澳大利亚新南威尔士州的上侏罗纪Talbragar化石鱼床中发现了一颗四足动物的牙齿。这是经过130多年的挖掘，在这个地方发现的第一个四足动物的证据。这颗牙齿可能来自一种颞棘两栖动物。在此，我们记录了这一发现，讨论了为什么在这个地方四足动物遗骸如此稀少的潜在解释，并就这颗牙齿是如何被保存下来的提供了假设。Lachlan J.

Abstract Protowenella is an early–middle Cambrian, isostrophically coiled, calcareous microfossil originally described from the middle Cambrian (Miaolingian) of Australia; it has been referred previously to the molluscan classes Monoplacophora, Helcionelloida or Gastropoda. A unique specimen from the Henson Gletscher Formation (Miaolingian Series, Wuliuan Stage) of North Greenland has a bilaterally symmetrical operculum preserved in place within the shell aperture. Paired cardinal processes and clavicles on the inner side of the operculum indicate that Protowenella was a hyolith morphologically close to the orthothecid Conotheca. Protowenella is transferred from Mollusca to Hyolitha, Order Orthothecida, Family Protowenellidae nov., representing a novel morphological departure from the generally slender cones of other hyoliths.

Protowenella是一种早中寒武纪、等向盘绕的钙质微化石，最初描述于澳大利亚中寒武纪苗岭期;它以前被称为软体动物纲单placophora, Helcionelloida或腹足类。北格陵兰岛五流期苗岭系Henson Gletscher组的一个独特标本在壳孔内保留了一个两侧对称的盖层。包盖内侧成对的基突和锁骨表明原温氏菌在形态上是一种接近于正鞘壳的水蛭。原温氏菌从软体动物转移到原温氏菌科原温氏菌科原温氏菌目水螅虫，代表了一种与其他水螅虫通常细长的球体不同的形态。瑞典乌普萨拉大学地球科学系(古生物学系)，Villavägen 16, SE-75236, John S.
