The Chinaman Gully Formation in South Australia is a regressive non-marine to marginal marine unit previously correlated with the ‘Eocene/Oligocene boundary’ type 1 Sequence Boundary Ta 4.3/4.4. It is barren of ostracods. Cytherellid, krithiid, pontocypridid, paracypridid and trachyleberidid ostracods are abundant in the underlying Blanche Point Formation (BPF), whereas bairdiids, xestoleberidids, hemicytherids and loxoconchids are more abundant in the Port Willunga Formation (PWF) which overlies the Chinaman Gully Formation. A major contrast in trachyleberidid, loxoconchid and hemicytherid species composition is evident between the BPF and PWF. A bootstrap variety of correspondence analysis identified Paracypris, Kuiperiana, Krithe, Tasmanocypris?, Argilloecia, Trachyleberis, Cytherella and Bythocypris as significant genera (indicating a palaeodepth of 120–200 m) in the BPF and Quadracythere, Hornibrookella?, Loxoconcha, Microcytherura, bairdiids, Schizocythere, Cytheralison, Kangarina and Xestoleberis a...

A diverse assemblage of foraminifera, radiolaria, and calcareous nannoplankton is recorded from basal beds of the Gearle Silstone in its type area. The calcareous nannofossils place the strata within the temperate-latitude CC8a Subzone and the Southern Ocean Sollasites falklandensis Subzone; the planktonic foraminifera indicate that the beds belong to the Hedbergella planispira Zone of the Australian region. The biozones suggest an early Albian age (later than the earliest Albian). Abundant calcareous and siliceous plankton and the Marssonella Association of benthonic foraminifera indicate normal-marine depositional conditions in a water depth of about 100 m. The transition from Windalia Radiolarite to Gearle Siltstone may reflect a marine transgressive pulse that reactivated bottom-water circulation and facilitated a significant increase in the calcareous biogenic component of the sediment. Deposition of the basal Gearle Siltstone was coincident with a major increase in bathymetry in the Papuan, Laura, C...

The Early Cretaceous Otway and Strzelecki Groups exposed on the southern coast of Victoria, Australia, have produced a fauna of dinosaurs that lived within the Antarctic Circle. As many as five or six species of hypsilophodontids numerically dominate the collections from there, but the rarer and more fragmentary theropod remains suggest a surprising diversity of carnivorous dinosaurs. A possible surangular and an isolated vertebra have characters considered diagnostic for Late Cretaceous oviraptorosaurs of the Northern Hemisphere. Other fossils suggest the presence of ornithomimosaurs, dromaeosaurids and neoceratopsians, and with the possible oviraptorosaur remains, challenge the widespread assumption that these animals originated on the northern continents.

Two further finds of Keratobrachyops australis Warren (Amphibia, Temnospondyli, Chigutisauridae) from the Early Triassic Arcadia Formation of Queensland provide new information concerning skull characters not noted in the holotype. The holotype of Xenobrachyops allos Howie (Amphibia, Temnospondyli, Brachyopidae) from the same locality is redescribed following the discovery of several features not previously noted. In addition, new but fragmentary brachyopoid material from the Arcadia and overlying Glenidal Formations provides information on derived character states within the superfamily. Controversy surrounds the correct familial composition of the superfamily Brachyopoidea, with the family Brachyopidae being allied by various authors with a diversity of other Triassic and Permian families. A cladistic analysis of a number of these families has been performed in an attempt to determine interfamilial relationships. Our results support a brachyopid-chigutisaurid dichotomy within the Brachyopoidea, but also...

Three trilobite species, Lisogorites mistus sp. nov., Taklamakania tarimensis W. T. Zhang and Ampyxinella rotundata W. T. Zhang, are described from the Yingan Formation near Kalpin in southern Xinjiang, NW China. They occur with graptolites in an assemblage of late Caradoc age. Lisogorites is an aberrant asaphid, and is considered to be a senior synonym of Trigonoaspis and Tangyaia. Ampyxinella is regarded as referable to the subfamily Endymioninae. The raphiophorid Taklamakania has only three thoracic segments and may have been derived from Ampyxina by neoteny. The morphological and taphonomical features of the trilobites suggest that this faunule lived on a soft muddy substrate in a quiet, deeper-water, slope environment of the ‘Raphiophorid Biofacies’. Palaeogeographically the Kalpin area was located on the northwestern slopes of the Tarim carbonate platform during Caradoc times. Closest zoogeographic relationships of this fauna are with South China, Kazakhstan, North China and eastern Australia.

Hadronomas was a large kangaroo similar in size to Simosthenurus occidentalis. Its pes was relatively long and robust, resembling those of the sthenurines Procoptodon and Sthenurus in possessing ligamentous specialisations of the fourth proximal phalanx, anteroposterior compression of fourth proximal and median phalanges, broad, blunt ‘hoof-like’ terminal fourth phalanx, a shallow calcaneocuboidal ‘step’, anteroposterior as opposed to mediolateral differentiation of the ankle joint, high, rounded profile of the astragalar trochleae and a reduced, medially situated proximal ventromedial facet of the cuboid. The upper and lower limb girdles resemble those of sthenurines in that the coracovertebral angle of the scapula is elevated and produced anteriorly in the form of a rectangular process. The innominate is anteroposteriorly broad and the ischium is flattened in cross section. The tibia possesses a sinuous shaft and an elongated, smoothly convex tibial crest that tapers gradually into the diaphysis. Hadron...

An Ordovician nautiloid ellesmerocerid originally described as Irianoceras antiquum (Plectronoceratidae) Kobayashi 1971 from Irian Jaya and assigned a probable age of post Tremadoc is shown to be a member of the Llanvirn ellesmerocerid genus Bactroceras Holm 1878 (Baltoceratidae). Irianoceras antiquum is placed in synonymy with Bactroceras latisiphonatum Glenister 1952 described from New South Wales, Australia. The new material provides a better analysis of the variability of the genotype, extends its geographic range, and documents the presence or former presence of upper Caradoc to lower Ashgill strata in Irian Jaya.

The genus Chasmazoon is introduced for Cellepora abdita MacGillivray (1895) from the Tertiary of Victoria. Chasmazoon abditum has colonies capable of both an encrusting and free-living mode of growth, and the latter were probably anchored by basal rhizoids. The large, simple orifices and striated, peristomial ovicells of C. abditum are distinctive, and Stichoporina parvicapitata Canu & Bassler (1935), which has closely similar characters, is considered to be synonymous.

Thin limestone beds are a minor component of the Lower Devonian Wilson Creek Shale in the Tyers-Walhalla area of Victoria. Age-diagnostic conodonts recovered are (1) Eognathodus sulcatus sulcatus, index to the sulcatus Zone (early Pragian), from the Thomson River south of Coopers Creek, and (2) Polygnathus dehiscens, index to the dehiscens Zone (early Emsian), from Jacobs Creek. The Wilson Creek Shale thus ranges from the sulcatus Zone to the dehiscens Zone, and is partly equivalent to the Coopers Creek Limestone (sulcatus Zone). Low-oxygen deposition existed in central Victoria over a considerably longer period in the Early Devonian than previously suspected.

Hausmannia papilio Feruglio is a widespread component of Albian fossil floras on Alexander Island, Antarctic Peninsula. Hausmannia cannot be separated from extant Dipteris and is best regarded as a foliage form genus of the latter.
