  • From the Lower Cretaceous of Lightning Ridge, New South Wales, Australia
    Isolated teeth of Anhangueria (Pterosauria: Pterodactyloidea) from the Lower Cretaceous of Lightning Ridge, New South Wales, Australia Tom Brougham1, Elizabeth T. Smith2 and Phil R. Bell1 1 School of Environmental and Rural Science, University of New England, Armidale, New South Wales, Australia 2 Australian Opal Centre, Lightning Ridge, New South Wales, Australia ABSTRACT The fossil record of Australian pterosaurs is sparse, consisting of only a small number of isolated and fragmentary remains from the Cretaceous of Queensland, Western Australia and Victoria. Here, we describe two isolated pterosaur teeth from the Lower Cretaceous (middle Albian) Griman Creek Formation at Lightning Ridge (New South Wales) and identify them as indeterminate members of the pterodactyloid clade Anhangueria. This represents the first formal description of pterosaur material from New South Wales. The presence of one or more anhanguerian pterosaurs at Lightning Ridge correlates with the presence of `ornithocheirid' and Anhanguera-like pterosaurs from the contemporaneous Toolebuc Formation of central Queensland and the global distribution attained by ornithocheiroids during the Early Cretaceous. The morphology of the teeth and their presence in the estuarine- and lacustrine-influenced Griman Creek Formation is likely indicative of similar life habits of the tooth bearer to other members of Anhangueria. Subjects Paleontology, Taxonomy Keywords Pterosauria, Cretaceous, Australia, Teeth Submitted 11 January 2017 Accepted 31 March 2017 Published 3 May 2017 INTRODUCTION Corresponding author Tom Brougham, Pterosaurs first appeared in the Late Triassic and diversified rapidly into the Jurassic.

The record in England is more diverse than previously recognized due to Iguanodon being a wastebasket genus throughout the Twentieth Century. Several new taxa, previously recognized as generically distinct by Harry Grovier Seeley, are named. The spatial and temporal distributions of iguanodonts are plotted on global maps as a key to un- derstanding the origin of the Cedar Mountain Formation iguanodonts. Keywords: Early Cretaceous, Iguanodonts, Dinosauria Resumen Los recientes descubrimientos de diversos iguanodontes en la Formación Cedar Mountain (Utah, EE.UU.) nos han llevado a valo- rar la diversidad global de los iguanodontes del Cretácico temprano. El registro en Inglaterra es más diverso de lo que previamente se ha reconocido, debido a que Iguanodon ha sido tratado como un género “cajón de sastre” a lo largo de todo el siglo XX.

  • A New Species from the Lower Cretaceous of Queensland, Australia
    The first record of the ichthyodectiform fish Cladocyclus from eastern Gondwana: A new species from the Lower Cretaceous of Queensland, Australia RODNEY W. BERRELL, JESÚS ALVARADO-ORTEGA, YOSHITAKA YABUMOTO, and STEVEN W. SALISBURY Berrell, R.W., Alvarado-Ortega, J., Yabumoto, Y., and Salisbury, S.W. 2014. The first record of the ichthyodectiform fish Cladocyclus from eastern Gondwana: A new species from the Lower Cretaceous of Queensland, Australia. Acta Palaeontologica Polonica 59 (4): 903–920. Cladocyclus is a genus of ichthyodectiform fish that is best known from fossils found in shallow marine Cretaceous deposits in Brazil and Morocco. Herein, a new species of Cladocyclus is described on the basis of a fossil that comprises an articulated skull and anterior part of the body, preserved as part and counter-part in what was originally a single eroded nodule of fluvially-deposited volcanolithic sandstone from the Lower Cretaceous (upper Albian) portion of the Winton Formation near Isisford, central-western Queensland, Australia. This specimen represents the first record of Cladocyclus in eastern Gondwana, and indicates that species of this fish may also have inhabited freshwater environments. The new species is assigned to the genus Cladocyclus based on the morphology of the cleithrum (the arms are oriented at approx- imately 90° to each other) and a mandibular articular facet that incorporates portions of the angular, the articular and the retroarticular. Cladocyclus geddesi sp. nov. can be distinguished from other congeners based on the possession of a more elongate horizontal arm of the cleithrum and a supraoccipital crest that is gently convex posteriorly. This discovery greatly expands the geographic range of Cladocyclus, and supports the idea of a distinct southern fish fauna in the seas surrounding the fragmenting Gondwanan landmasses during the mid-Cretaceous.
