Conodont
Siluro-devonian Conodonts from the Camelford Limestone, Wellington, New
South Wales, Australia

Abstract:
Conodont data have been utilized to identify
the Silurian/Devonian boundary within the Camelford Limestone near Wellington,
NSW. Conodont faunas are documented from the eosteinhornensis Zone to early
delta Zone with one new species of Walliserodus (W. multistriatus) and two
new species of Ozarkodina (O. brocki and O. camelfordensis) described. An
apparatus reconstruction of Belodella anomalis is also presented.

Early Triassic coprolites from Australia and their palaeobiological significance
Author: CAROLINE NORTHWOOD1

Publisher: Blackwell Publishing
Abstract:
Coprolites from the Arcadia Formation, Queensland, Australia, were studied in conjunction with the vertebrate fossil assemblages from two localities to maximize our understanding of the palaeoecology of these Early Triassic deposits. Criteria used by other researchers to identify the producers of coprolites were found to be of little value in the Arcadia Formation specimens. Using a combination of shape, biostratigraphic distribution, size and included remains some of the coprolites are attributed to basal archosauromorphs and fish whereas others could not be identified. Perhaps the most important attribute of the Arcadia coprolites is that they preserved rare organisms such as cyanobacteria, insects and other arthropods, and a diversity of fish. Estimates of the number of actinopterygians and dipnoans preserved in coprolites significantly increased relative abundance estimates based on skeletal elements alone. Although coprolites are an important source of palaeobiological information, this information is limited by our poor understanding of the taphonomic processes involved in the fossilization of faecal matter and by the near impossibility of assigning coprolites to specific producers.

Eurypterida
A New Eurypterid (Chelicerata: Eurypterida) from the Upper Devonian Gogo
Formation of Western Australia, With A Review of the Rhenopteridae

Abstract:
A new eurypterid, Rhenopterus waterstoni sp.
nov., is described from the Gogo Formation (Frasnian, Upper Devonian) of
Western Australia. This species is distinguished from related forms by the
tuberculation of the anteriormost tergite and crenulated posterior margins
of the carapace and opisthosomal segments. It is the only eurypterid specimen
known from the Gogo Formation, the most complete eurypterid from Australia,
and also the youngest representative of Rhenopterus in the fossil record.
Structures retrieved from between the prosomal-opisthosomal juncture comprise
polygonal tubes 30?40 m in diameter, which are interpreted as sarcomeral
sheaths of muscular tissue. Rhenopterus is reviewed: R. latus Stormer, 1936
is synonymized with R. diensti Stormer, 1936 as it is here recognized as
a female sexual dimorph; R. maccarthyi (Kjellesvig-Waering, 1934) is an
orthocone nautiloid.

Polyplacophora
Lower Devonian Polyplacophora from New South Wales, Australia
Authors: Richard D. Hoare1; John R. Farrell2
Source: Palaeontology, November 2004, vol. 47, no.
6, pp. 1495-1506(12)
Publisher: Blackwell Publishing
Abstract:
Silicified polyplacophorans are common in the
Lower Devonian Garra Formation in New South Wales. Four taxa occur within
the lower 237 m of the formation at 14 horizons associated with an abundant
and diverse fauna. Chelodes calceoloides Etheridge ranges through the section.
New taxa are Chelodes cordatus sp. nov., Acutichiton depressolatus sp. nov.,
and Jugochiton patulus gen. and sp. nov. A single plate of an indeterminate
genus occurs in the lower portion of the Camelford Limestone.
