“…Lonchodectid pterosaurs represent a minor radiation that was apparently restricted to the Early Cretaceous (Berriasian–Cenomanian) of Europe. This clade has also been tentatively identified in the Albian of Australia (Molnar and Thulborn 2007 ), but more recently this material has been provisionally regarded as closely related to, but not a member of, the Anhangueridae (Kellner et al 2011 ) (Table 1 ).…”

The biogeographical history of pterosaurs has received very little treatment. Here, we present the first quantitative analysis of pterosaurian biogeography based on an event-based parsimony method (Treefitter). This approach was applied to a phylogenetic tree comprising the relationships of 108 in-group pterosaurian taxa, spanning the full range of this clade's stratigraphical and geographical extent. The results indicate that there is no support for the impact of vicariance or coherent dispersal on pterosaurian distributions. However, this group does display greatly elevated levels of sympatry. Although sampling biases and taxonomic problems might have artificially elevated the occurrence of sympatry, we argue that our results probably reflect a genuine biogeographical signal. We propose a novel model to explain pterosaurian distributions: pterosaurs underwent a series of ‘sweep-stakes’ dispersal events (across oceanic barriers in most cases), resulting in the founding of sympatric clusters of taxa. Examination of the spatiotemporal distributions of pterosaurian occurrences indicates that their fossil record is extremely patchy. Thus, while there is likely to be genuine information on pterosaurian diversity and biogeographical patterns in the current data-set, caution is required in its interpretation.

Over a decade after the last major review of the Cambridge Greensand pterosaurs, their systematics remains one of the most disputed points in pterosaur taxonomy. Ornithocheiridae is still a wastebasket for fragmentary taxa, and some nomenclatural issues are still a problem. Here, the species from the Cretaceous of England that, at some point, were referred in Ornithocheirus, are reviewed. Investigation of the primary literature confirmed that Criorhynchus should be considered an objective junior synonym of Ornithocheirus. Taxonomic review of more than 30 species known from fragmentary remains showed that 16 of them are undiagnosable (nomina dubia): Palaeornis cliftii, Cimoliornis diomedeus, Pterodactylus compressirostris, Pterodactylus fittoni, Pterodactylus woodwardi, Ornithocheirus brachyrhinus, Ornithocheirus carteri, Ornithocheirus crassidens, Ornithocheirus dentatus, Ornithocheirus enchorhynchus, Ornithocheirus eurygnathus, Ornithocheirus oxyrhinus, Ornithocheirus scaphorhynchus, Ornithocheirus tenuirostris, Ornithocheirus xyphorhynchus, and Pterodactylus sagittirostris. Fourteen species are considered valid, and diagnoses are provided to all of them: Ornithocheirus simus, Lonchodraco giganteus comb. n., Lonchodraco machaerorhynchus comb. n., Lonchodraco(?) microdon comb. n., Coloborhynchus clavirostris, ‘Ornithocheirus’ capito, Camposipterus nasutus comb. n., Camposipterus(?) sedgwickii comb. n., Camposipterus(?) colorhinus comb. n., Cimoliopterus cuvieri comb. n., ‘Ornithocheirus’ polyodon, ‘Ornithocheirus’ platystomus, ‘Pterodactylus’ daviesii, and ‘Ornithocheirus’ denticulatus. These species are referred in the genera Ornithocheirus, Lonchodraco gen. n., Coloborhynchus, Cimoliopterus gen. n., and Camposipterus gen. n., but additional genera are probably present, as indicated by the use of single quotation marks throughout the text. A cladistic analysis demonstrates that Anhangueridae lies within a newly recognized clade, here named Anhangueria, which also includes the genera Cearadactylus, Brasileodactylus, Ludodactylus, and Camposipterus. The anhanguerian ‘Cearadactylus’ ligabuei belongs to a different genus than Cearadactylus atrox. Lonchodraconidae fam. n. (more or less equivalent to Lonchodectidae sensu Unwin 2001) is a monophyletic entity, but its exact phylogenetic position remains uncertain, as is the case of Ornithocheirus simus. Therefore, it is proposed that Ornithocheiridae should be constricted to its type species and thus is redundant. Other taxa previously referred as “ornithocheirids” are discussed in light of the revised taxonomy.

“…Two pteranodontoid pterosaur taxa are currently recognised in Australia: Mythunga camara (QM F18896); and Aussiedraco molnari (QM F10613), both from the Lower Cretaceous of central Queensland. The jaw fragment WAM 68.5.11 (Kear, Deacon & Siverson, 2010) and partial mandible QM F44423 (Fletcher & Salisbury, 2010) possibly represent distinct ornithocheiroid taxa—the former based on its temporal separation from the aforementioned Queensland taxa and the latter from the distinct morphology of the mandibular symphysis (Kellner, Rodrigues & Costa, 2011). In addition, the azhdarchid ulna (WAM 60.57) from the Late Maastrichtian of Western Australia (Bennett & Long, 1991), and the ctenochasmatoid humeral fragment (QM F42739) (Fletcher & Salisbury, 2010) most likely represent distinct Australian pterosaur taxa.…”

“…The taxonomic status of Australia’s record of Cretaceous pterosaurs has been reviewed recently and comprehensively by Fletcher & Salisbury (2010), and also by Kellner, Rodrigues & Costa (2011). Following the pterosaur phylogeny of Andres, Clark & Xu (2014), material representative of three clades of pterodactyloid pterosaurs has been identified from Australia: pteranodontoids (Molnar & Thulborn, 1980; Molnar & Thulborn, 2007; Molnar, 1987; Kellner et al, 2010; Kellner, Rodrigues & Costa, 2011); ctenochasmatoids (Fletcher & Salisbury, 2010); and azhdarchids (Bennett & Long, 1991; see Fig. 2).…”

Isolated teeth of Anhangueria (Pterosauria: Pterodactyloidea) from the Lower Cretaceous of Lightning Ridge, New South Wales, Australia

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.
