摘要:

New stromatolite taxa are described from the Glengarry Group, Glengarry Basin (formerly part of the Nabberu Basin), Western Australia, as part of ongoing biostratigraphic studies of Proterozoic sequences in Western Australia. A new group and form,Wilunella glengarricais proposed, and two new forms,Kussoidella karalundienisandSegosia finlaysoniensisare circumscribed. In addition, three other forms, represented only by poorly preserved specimens and as yet insufficiently known for formal taxonomic designation, are briefly described. The assemblage differs from that of the overlying Earaheedy Group, and can be used to distinguish basal Glengarry Group sequences from outliers of the lithologically similar basal Earaheedy Group. The Glengarry Group taxa have not been reported outside the Glengarry Basin, and are therefore of little use at present for inter-regional correlation. However, the ranges of the previously described groupsKussoidellaandSegosiaare consistent with the probable 1·8 Ga or older age of the Glengarry Group.

摘要:

The Fanning River Group is among the best exposed marine-dominated Devonian sequences in eastern Australia. It consists of limestone, sandstone and conglomerate of shallow marine origin, which form the basal sequence of the Burdekin Basin. Sixteen species and subspecies (9 new) of rugose corals are described from outcrops of the Fanning River Group exposed in the Kirkland Downs, Boundary Creek and Lime Creek areas; these areas represent the north and northwestern margins of the Burdekin Basin during the early Givetian transgression. The coral taxa are determined as:Lythophyllum proliferumsp. nov.,Endophyllum jellisp. nov.,Iowaphyllum schlueteri(Etheridge 1898),Blysmatophyllum isisensePedder 1970,Blysmatophyllum multigemmesp. nov.,Blysmatophyllum? sp.,Sanidophyllum kirklandensesp. nov.,Spongophyllum (Beugniesastraea) variabilissp. nov.,Australophyllum cyathophylloides yohisubsp. nov.,Xystriphyllum dotswoodensesp. nov.,Xystriphyllumsp.,Taimyrophyllum crassiseptatumsp. nov.,Acanthophyllum (Acanthophyllum)sp.,Amaraphyllum amoenumPedder 1970,Argutastreasp., andAristophyllum planotabulatumsp. nov.

摘要:

The Cambrian acrotretid brachiopodNeotretaSobolev 1976 is reviewed and re-illustrated, based on new material of the type species,N. tumidaSobolev 1976, from the lower Upper Cambrian of Siberia;Neotreta orbiculataKoneva 1990, originally described from the Middle Cambrian of Kazakhstan, has been obtained from roughly coeval beds in Shropshire, England;Neotreta pusillaKoneva 1986 was unavailable for study. Two new species,N. davidiandN. karagailensis, are described from Queensland, Australia, and Kirgizia, Central Asia respectively.

摘要:

In 1919, Jacques Deprat, a French geologist, was recognized as responsible for introducing apocryphal trilobites into the material he collected in Vietnam and South China (Yunnan). The attempt to rehabilitate his reputation at a special session of the French Geological Society is based on Durand-Delga's investigations. However, many of the arguments presented by Durand-Delga seem controversial and are discussed below.
