Late Ordovician radiolarians are described from allochthonous limestone breccia deposits of the graptolitic Malongulli Formation of central New South Wales. Included among the forms are the new ‘palaeoactinommid’ genus Kalimnasphaera with new species K. maculosa, the new entactiniid species, Entactinia subulata, and the new anakrusid species, Auliela taplowensis. A number of other entactiniids and the first recorded Ordovician ‘rotasphaerids’ are placed in open nomenclature. Graptolite faunas of the Malongulli Formation indicate that the deposits range in age from the Eastonian Zone of Dicranograptus hians kirki to the Bolindian Zone of Climacograptus uncinatus, that is, from latest Caradoc to early or middle Ashgill in age. This is only the second known well-preserved radiolarian assemblage to be illustrated from Late Ordovician (late Caradoc–Ashgill) successions, and the earliest known from Australia. The radiolarians typically occur in tabularly shaped, laminated lime-mudstone clasts with an abundance of siliceous sponge remains. These clasts appear to be formed from peri-platform ooze of the ‘deeper-water’ slope facies, which became incorporated in debris flows moving into the adjoining basin.

AbstractThe trilobite fauna of the middle Silurian (Telychian to possibly earliest Sheinwoodian) Tomcat Creek limestone in the Broken River Province of north Queensland is dominated by the suborder Illaenina, including illaenimorphs (Illaeninae and Bumastinae) and members of the Scutelluidae. Scutelluidae are most diverse, with eight genera, of whichDolabrapex,Iotoryx,Perizostra, andQuintoniaare new.Perizostrais the first scutelluid with a cephalon that may be described as of phacomorph appearance. Illaenimorphs are represented by three genera, includingOpsypharus, which is regarded as a senior synonym ofParacybantyxbut distinct fromFailleanawith which it has been placed in synonymy by some authors. Thirteen species are new:Cybantyx?ergodes,Opsypharus pandanensis,Australoscutellum talenti,Dolabrapex acomus,Illaenoscutellum psephos,Iotoryx clarksoni,Japonoscutellum mawsonae,J. drakton,J. fractum,Kosovopeltis avita,Perizostra campbelli,Quintonia arata, andQ. pavo. A species ofStenopariais placed in open nomenclature. The species ofAustraloscutellum,Illaenoscutellum, and possiblyKosovopeltisare the oldest known representatives of those genera. These genera andJaponoscutellumare also common in faunas from limestones of Wenlock to Ludlow age in central western New South Wales, reflecting the similarity in lithofacies. The monotypic Late Ordovician genusCraigheadia, which has been regarded as a scutelluid, belongs to the Lichidae and is probably a junior synonym ofLeiolichas.
