![]() ![]() Seed cone scales assigned to the genus Schizolepidopsis are widespread in Late Triassic to Cretaceous Eurasian deposits. Leslie, Andrew B Glasspool, Ian Herendeen, Patrick S Ichinnorov, Niiden Knopf, Patrick Takahashi, Masamichi Crane, Peter R from the Early Cretaceous (Aptian- Albian) of Mongolia. Pinaceae-like reproductive morphology in Schizolepidopsis canicularis sp. Wintonotitan and Australovenator) and more derived forms (e.g. These new taxa, along with the fragmentary remains of other taxa, indicate a diverse Early Cretaceous sauropod and theropod fauna in Australia, including plesiomorphic forms (e.g. ![]() Conclusion/Significance The occurrence of Australovenator from the Aptian to latest Albian confirms the presence in Australia of allosauroids basal to the Carcharodontosauridae. We compare an isolated astragalus from the Early Cretaceous of southern Australia formerly identified as Allosaurus sp., and conclude that it most-likely represents Australovenator sp. ![]() nov., a derived lithostrotian titanosaur and Australovenator wintonensis gen. nov., a basal titanosauriform Diamantinasaurus matildae gen. Methodology/Principal Findings We describe three new dinosaurs from the late Early Cretaceous (latest Albian) Winton Formation of eastern Australia, including Wintonotitan wattsi gen. A better understanding of the Australian dinosaurian record is crucial to understanding the global palaeobiogeography of dinosaurian groups, including groups previously considered to have had Gondwanan origins, such as the titanosaurs and carcharodontosaurids. Most taxa are known from fragmentary isolated remains with uncertain taxonomic and phylogenetic placement. Sloan, Trish Elliott, David A.īackground Australia's dinosaurian fossil record is exceptionally poor compared to that of other similar-sized continents. ![]() New Mid- Cretaceous (Latest Albian) Dinosaurs from Winton, Queensland, Australia ![]()
