Eutreptodactylus itaboraiensis from Late Paleocene karst deposits of eastern Brazil is the oldest and most primitive member of the Cuculidae known to date. It is one of the oldest fossils that can be placed in a modern family of birds. The zygodactyl condition, characterising the cuculids, is present in Eutreptodactylus, but the relative rotation of the trochlea metatarsi IV is slight in comparison with that in extant cuculids, suggesting that this bird may not have been an obligate zygodactyl form. Since zygodactyly had developed within the Cuculiformes by the Late Paleocene, it follows that the other family in this order, the Musophagidae, must have diverged by the early part of the Cainozoic.

Foraminifea from the type section of the Giralia Calcarenite indicate an upper zone P12 correlation and a Middle Eocene age (probably within the interval 41.5–40.5 Ma, BKSA95 time scale). The type Giralia Calcarenite is considered to represent one sequence (with maximum thickness of 40–50 m preserved on the Gascoyne Platform) and to reflect late transgressive and early highstand deposition about a maximum flooding event. Initial retrogradation of the shoreline produced a maximum water depth of about 50 m at the type locality (5–6 m above base of stratigraphic section). The formation may correlate with shallow marine deposits found elsewhere in the Southern Carnarvon Basin (e.g. Eocene limestones at Yaringa and Red Bluff, and the Merlinleigh Sandstone), and correlates with Middle Eocene transgressive units in the Perth, Eucla, Great Australian Bight and Otway Basins.

The monocotyledon macrofossil Desmiophyllum sp. α Seward & Conway is recognised as being close in its cuticular features and stomatal sculpturing to several New Zealand and Mascarene species of Cordyline. However, because the fossil cannot be placed unequivocally in Cordyline it is assigned to a new form genus Paracordyline as P. kerguelensis with affinities to the extant aborescent woody monocot Cordyline (Lomandraceae).

Stromatoporoids are well represented in the carbonate depositional phases of the Middle-Upper Silurian Jack Formation, the Lower-Middle Devonian Shield Creek Formation and Broken River Group of north Queensland. A total of 4 species of Labechiida, 4 species of Actinostromida, 14 species (4 new) of Clathrodictyida and 5 species (1 new) of Stromatoporellida are described and illustrated. They include the new species Gerronostroma doseyense, G.? apertum, Schistodictyon jackense, Atelodictyon repandum and Hermatostroma malletti. The fauna comprises representatives of Cystostroma, Labechiella, Stylostroma, Actinostroma, Aculatostroma, Ecclimadictyon, Plexodictyon, Anostylostroma?, Nexililamina, Pseudoactinodictyon, Tienodictyon, Simplexodictyon, Stromatopororella, Stictostroma, Trupetostroma?, Amnestostroma and Stachyodes. Included are revisions of a number of C.W. Mallett's species first described in the early 1970s. The genus Nexililamina Mallett is reinterpreted as a clathrodictyid. The history of the ‘less...

Microfossil assemblages are described from the early Neoproterozoic Madley and Browne Formations, western Officer Basin. One chert and eleven siliciclastic samples yielded microfossils. Myxococcoides cantabrigiensis occurs as pustular mats in the chert sample and Eomicrocystis malgica, Pterospermopsimorpha granulata, Skiagia sp. cf. S. pusilla, and undetermined species of Obruchevella, Heliconema, and Trachystrichosphaera are present in acid macerated samples. Leiosphaeridia spp. and Siphonophycus spp. are also found in fine-grained siliciclastic samples, with clusters of Synsphaeridium sp. in some samples. These findings enable a more substantial reconstruction of the palaeoenvironment of Supersequence 1 in the western Centralian Superbasin. The acanthomorph acritarchs are considered to be planktonic eucaryotes washed into environments which ranged from coastal sabkha through to tidal flats, which may be the source of the prokaryotic, benthic, matforming cyanobacteria.
描述了Officer盆地西部新元古代早期Madley组和Browne组的微化石组合。一块燧石和11块硅橡胶样品中发现了微化石。在燧石样品中，坎塔伯黏菌以脓疱席的形式出现;在酸浸过的样品中，出现了马氏微囊藻、肉芽pterospmopsimorpha granulata、Skiagia sp. cf. S. pusilla和未确定种类的奥布鲁切氏菌、Heliconema和Trachystrichosphaera。细粒硅塑料样品中也发现了Leiosphaeridia sp.和Siphonophycus sp.，在一些样品中也发现了簇生的Synsphaeridium sp.。这些发现为进一步重建中侏罗系西部超级盆地超层序1的古环境奠定了基础。棘藻藻被认为是浮游真核生物，被冲刷到从沿海sabkha到潮滩的环境中，这可能是原核、底栖、平台蓝藻的来源。

The Early Permian amphibian Archegosaurus decheni Goldfuss, originally reported from Germany, is described, based on a collection of thirteen skulls housed in the Museum of Victoria, Melbourne, Australia. New and previously poorly known features described include: the presence of an intermaxillary foramen, pterygoid-vomer contact, well developed adductor flange of the pterygoid, very long choanae, absence of interchoanal and parachoanal tooth rows, and development of paired anterior palatal fossae. A scheme of cladistic relations between archegosauroid genera and other temnospondyl families is proposed.

Belemnites are nektopelagic cephalopods which developed a widespread pattern of distribution in the Jurassic, and most authors have accepted that their centre of origin was Europe. Available data suggest that the belemnites developed a global distribution only in the Toarcian, some 15 Ma after their first appearence in the European Hettangian. Development of the Boreal and Tethyan belemnite realms took place in the Middle Jurassic and continued through to the Cretaceous. New data from Argentina and the Antarctic Peninsula reaffirms the development of the global distribution of belemnites in the Toarcian, and sheds new light on the biogeographical patterns for the Jurassic of the southern hemisphere. This has considerable implications for understanding the development of faunal realms in the Mesozoic.

An incomplete indeterminate crocodilian angular from the Miocene Bannockburn Formation, Central Otago, South Island, New Zealand is described. The fossil (probably a new taxon) represents the first undoubted occurrence of a crocodilian in New Zealand. Local palaeoclimatic indicators suggest the crocodilian lived in a temperate climate.

Fossil bones of a new genus and species of rail (Aves: Rallidae) are described from one million year old shoreline deposits near Marton, North Island, New Zealand. Associated bones indicate the presence of a specifically indeterminate rail, an indeterminate avian species, and a moa (Aves: Dinornithiformes). These are the first described fossil terrestrial carinates from deposits older than 100,000 years in New Zealand.
