摘要:

Rugose and tabulate corals of Frasnian (early Late Devonian) and pre-Frasnian Devonian and Silurian(?) ages from Irian Jaya (western New Guinea), Indonesia, are described and illustrated for the first time. The Frasnian corals are the most important; they occur in the uppermost part of the Modio Formation (redefined), are well-preserved and suggest a biogeographic linkage to Western Australia. The source carbonates may represent a reef environment.

摘要:

Faunal remains from Gua (cave) Siti Nafisah, central Halmahera, reveal that until at least 1,870 ybp, Halmahera supported a non-volant mammal fauna which was predominantly of New Guinean origin. It consisted of at least three marsupial species; a wallaby of the genusDorcopsis, a bandicoot (family Peroryctidae, genus indet.), and the Halmahera Group endemic cuscusPhalanger ornatus. Rattus morotaiensis, which is also endemic to the Halmahera Group, was also probably present. The wallaby and bandicoot (both terrestrial species) are now extinct, while the arboreal cuscus and rat survive. Faunal remains from the Uattamdi site, on the small island of Kayoa, do not include the remains of bandicoots or wallabies.

摘要:

A number of palynomorphs of Palaeocene and Eocene age and Australasian origin, commonly attributed to the family Proteaceae, is compared to modern genera and species using a combination of conventional light microscopy, phase contrast and scanning electron microscopy. A significant percentage of these appears to be closely comparable to modern Proteaceae taxa. Comparisons permit the recognition of three modern subfamilies, eight tribes and eight to ten subtribes.

摘要:

A species of the family Capitosauridae, previously known only from immature specimens, is now known from an adult which is typically capitosaurian in proportions, although allometrically quite different from the juveniles. It is proposed that the oblique ridge of the pterygoid did not house the stapes in capitosaurs. Instead the stapes passes posterior to the oblique ridge with its distal end only entering the otic notch.

摘要:

Three trilobite species,Lisogorites mistussp. nov.,Taklamakania tarimensisW. T. Zhang andAmpyxinella rotundataW. 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.Lisogoritesis an aberrant asaphid, and is considered to be a senior synonym ofTrigonoaspisandTangyaia. Ampyxinellais regarded as referable to the subfamily Endymioninae. The raphiophoridTaklamakaniahas only three thoracic segments and may have been derived fromAmpyxinaby 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.

摘要:

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 thesulcatusZone (early Pragian), from the Thomson River south of Coopers Creek, and (2)Polygnathus dehiscens, index to thedehiscensZone (early Emsian), from Jacobs Creek. The Wilson Creek Shale thus ranges from thesulcatusZone to thedehiscensZone, and is partly equivalent to the Coopers Creek Limestone (sulcatusZone). Low-oxygen deposition existed in central Victoria over a considerably longer period in the Early Devonian than previously suspected.
