Sandwiched between Miocene limestones of the Mannum Formation and Morgan Limestone in the western Murray Basin, the Finniss Clay and Cadell Marl contain different foraminiferal faunas with varying taphonomic grades. At the Mannum Pumping Station section, the Finniss Clay fauna has a low diversity, frequent shallow-water forms, and a poor taphonomic grade. In what was the deeper part of the basin at Waikerie, a diverse fauna with well-preserved small species is recorded in sediments equivalent to the Finniss Clay. In contrast, the Cadell Marl from various localities comprises a well-preserved and diverse biofacies with both shallow and deeper water taxa. These contrasts suggest different depositional environments: shallower and warm during deposition of the Finniss Clay and nutrient-rich, dysaerobic and deeper water during deposition of the Cadell Marl. The shallowing event indicated by faunas from the Finniss Clay was due to falling sea level close to the early/middle Miocene boundary, whereas the Cadell ...

Published accounts of the Australian Triassic euthycarcinoid Synaustrus brookvalensis have not documented all known material, and are inconsistent in several respects with better known euthycarcinoids. Synaustrus is most closely related to Euthycarcinus. New morphological findings and interpretations (e.g., a slender seta on each leg annulation; a series of articulated cephalic sternites) confirm the similarity of Synaustrus to other euthycarcinoid taxa. The evidence presented here allies euthycarcinoids with atelocerates, but they cannot be positioned higher than the stem-lineage of Atelocerata. Synaustrus and other genera possess trunk apodemes analogous to those of symphylans. Sternal pores in euthycarcinoids resemble coxal vesicles, though this conflicts with other morphological indications of aquatic habits.

Skull bones in early lungfish contain permanent insignia of the sensory lines of the head, but osteological evidence of sensory lines in derived lungfish is reduced to foramina for nerves to neuromasts, superficial grooves, or elevated ridges on some bones. This is particularly evident in anterior bones, making definition of these bones difficult, and creating problems for phylogenetic analyses. Despite a close association of the sensory lines with the bones of the developing skull in the Australian lungfish, Neoceratodus forsteri, few traces of the lines remain in the bones of the adult animal. Among derived dipnoans, Mioceratodus, a genus of neoceratodont fossil lungfish from Tertiary deposits in central and northern Australia, is unusual because traces of the supraorbital sensory line are retained in the anterior skull roofing bones of large specimens. Equivalent traces are absent from the rostral bones of N. forsteri, and from small specimens of Mioceratodus. The supraorbital sensory line grooves in M...

The discovery of a rich assemblage of microfossils from the Neoproterozoic western Officer Basin (Centralian Superbasin) provides a more complete understanding of the biostratigraphy of this Basin. The microfossils are found in Supersequence 1 (∼800 Ma) in Western Australia. The assemblages are comprised of acritarchs and cyanobacteria isolated by acid maceration from siliciclastics of the Browne (Madley), Hussar, Kanpa and Steptoe Formations. The distinctive acritarchs Cerebrosphaera buickii, Satka colonialica, Stictosphaeridium sinapticuliferum and Pterospermopsimorpha insolita are of particular interest in the Neoproterozoic. These taxa are found in similar depositional environments in Spitsbergen, Arizona, Canada and Siberia. This evidence, together with lithostratographic correlations, isotope chemostratigraphy, and sequence analysis contributes to the continuing development of Neoproterozoic stratigraphy.

A complete large mandible from the early Miocene Neville's Garden Site, Riversleigh, northwestern Queensland, Australia, represents a new genus and species of songbird, Longimornis robustirostrata. L. robustirostrata is referred to the Oriolidae, closest to the figbirds Sphecotheres. It is the third named passerine from the Tertiary of Australia.

Material of giant temnospondyl amphibians is described from two localities in the Early to Middle Triassic Narrabeen Group of the Sydney Basin, Australia. The capitosaurid Bulgosuchus gargantua gen. et. sp. nov. from the Bulgo Sandstone (Scythian) at Longreef, represented by an incomplete mandible and a femur, is the largest known Early Triassic temnospondyl and the earliest occurrence of a temnospondyl in the Sydney Basin Triassic. B. gargantua is phenetically most similar to Paracyclotosaurus and to ‘P’. gunganj, but also shows affinities with Eryosuchus and Middle Triassic species of ‘Parotosuchus’. An anterior portion of a large mandible from the Terrigal Formation (late Scythian-early Anisian) at Bouddi is also described and tentatively referred to the Capitosauridae, but is generically indeterminate. The morphology of the post-glenoid area in members of the Capitosauridae is described, and derived characters of the capitosaurid mandible are provided.

A reexamination of Martiniella Grabau and Tien, 1931 reveals that the type species, M. nasuta Grabau and Tien, is a nomen nudum. Martiniella is thus restricted to its type species. A new genus, Chuiella gen. nov., is proposed to host the other Chinese species, previously ascribed to Martiniella Grabau and Tien, 1931. In addition, a detailed microfacies, taphonomic and palaeoecological analysis of a fossiliferous bed that contains abundant specimens of Chuiella gen. nov. from the Early Carboniferous Kelitag Formation of the Damusi area in the western Kunlun Mountains, Xinjiang Province, northwest China, reveals that species of Chuiella probably lived in a clean, warm, shallow-water marine, high energy environment. A review of all described species of Chuiella suggests this genus is characteristic of the Tournaisian and restricted to the palaeo-equatorial Eastern Tethyan region. Two species of Chuiella are described, including one new species: Chuiella aitegouensis gen. et sp. nov.
对martinella Grabau和Tien(1931)的重新考察表明，模式种M. nasuta Grabau和Tien是一种雌性裸种。因此，马提尼拉仅限于它的模式种。本文提出了一个新属Chuiella gen. nov.，以取代之前归属于Martiniella Grabau和Tien(1931)的其它中国种。此外，通过对新疆昆仑山西部大木泗地区早石炭世克里塔格组丰富的丘埃拉属化石层的微相、地学和古生态分析，表明丘埃拉属可能生活在清洁、温暖、浅水、高能量的海洋环境中。对所有已描述的Chuiella种的回顾表明，该属是Tournaisian的特征，仅限于古赤道东特提斯地区。报道了两种丘ella，包括一新种:aitegouensis gen. et sp. nov。

The problematic Mississippian-Cretaceous fossil Shamovella (=Tubiphytes) has been referred to the cyanobacteria, algae and invertebrates (sponges, hydrozoans, foraminifera). These conflicting interpretations of affinity are based on morphology. Hitherto there has been little emphasis on the palaeoecological and palaeogeographic distribution of Shamovella, although this could provide further information relating to its systematic position. Previous reports of Shamovella document occurrence in shallow-marine warm water, often reefal, associations. However, in the Late Sakmarian (Sterlitamakian) Hoeniti Member of the Maubisse Formation near Bisnain, eastern West Timor, Shamovella obscura (Maslov) Riding is locally abundant and is associated with brachiopods of temperate water affinity. Shamovella obscura occurs in grainstones with abraded and bored bioclasts, indicating shallow-water, but dasycladaleans, other calcareous algae, and also cyanobacteria are absent. This indicates that Shamovella could occupy te...
