Carboniferous fossils from the Kuttung rocks of New South Wales

Brachiopod, polyzoan, molluscan, conulariid, and blastoid faunas from the Booral and Isaacs Formations on the south-eastern side of the Gloucester trough, north of Newcastle, N.S.W., are described. Five new brachiopod genera are established—the spiriferoids Alispirifer, Liriplica, and Spinuliplica; the rhynchonelloid Lissella; and the terebratuloid Booralia. Twenty new species and one new subspecies are named and described, including the type species of all the new genera.

Australasian Typhinae (Gastropoda) with notes on the subfamily

The Typhinae are a rare but widely distributed Muricid group. Because of their rarity they are of little value for local geological correlation, but are useful for regional correlation and palaeogeography, and as facies indicators.Tertiary distributions indicate distinct American and Australo-European provinces and probably a third, Javanese province. The modern American fauna remains distinct. The single living European species is related to a living species on the west coast of South and Central America.

Reef-controlled distribution of Devonian microplankton in Alberta

Upper Devonian hystrichospherids of the off-reef Duvernay fades in Alberta, Canada, can be combined into three artificial groups that have different distribution patterns with regard to reefs. Simple spherical forms are widespread, from beds inter-fingering with reef carbonate into, off-reef areas. Thin-spined species are also widespread, but are seldom found within one mile of reefs. Thick-spined and polyhedral forms occur in off-reef strata, but seldom near reefs. All types increase in abundance with increasing distance from reefs.

Algal growths in the Rhaetic Cotham Marble of southern England

The Cotham Marble horizon in the Upper Rhaetic of southern England includes the two well-known rocks, Landscape Marble and Crazy Cotham Marble. Previous hypotheses concerning the origin of Landscape Marble are listed and the widely quoted gas-bubble explanation is discussed critically. An algal origin is proposed for the Landscape Marble, and the Crazy Cotham Marble is shown to be a current-concentrated breccia.

Lower Palaeozoic corals from New South Wales

A collection of corals from an area of some 30 square miles near Wellington, in central-western New South Wales, is described. These comprise twelve rugose and sixteen tabulate species from stratigraphic horizons, ranging from probable Upper Ordovician to Lower or Middle Devonian. Species of the rugose genera Phaulactis, Entelophyllum, Disphyllum, Palaeophyllum, Tryplasma, Nipponophyllum, and Coronoruga gen.

The fossil cycads [Fourth Annual Address, delivered 8 March 1961]

The fossils considered are those in which attribution of one organ to the Cycadales (in the strict sense) is supported by the evidence from a different organ believed to be of the same plant. It thus deals with Palaeocycas+Bjuvia; Androstrobus prisma+Pseudoctenis lanei; Androstrobus spp.+Beania spp.+Nilssonia spp. Two classic fossil Cycads, Cycadospadix and Dioonitocarpidium, are considered not fully convincing. The kind of evidence needed is mentioned and the need is urged for assembling separate fossil organs into further synthetic plants.

Small Naiadites obesus from the Calciferous Sandstone Series (Lower Carboniferous) of Fife

Small specimens of Naiadites occur at two horizons in the Calciferous Sandstone Series of Eastern Fife. At one horizon the small shells constitute an indigenous 'life-assemblage' (now a fossil community), and are described as dwarfed, whereas at the other the shells are exotic, comprising a fossil assemblage that should be termed a 'pebble necrocoenosis'. Variation is illustrated, and the affinities of these small Naiadites are re-examined. All are referred to the species N. obesus s.l.
