Sauropod dinosaur teeth from the lower Upper Cretaceous Winton Formation of Queensland, Australia and the global record of early titanosauriforms

“…However, the Winton Formation fossil flora is co-dominated by coniferophytes and angiosperms [111,113]. Coniferophytes are common and diverse, with cupressaceans ( Austrosequoia wintonensis [50]), araucariaceans (several Araucaria morphotypes [111,113] and E. microcarpa [51]) and podocarpaceans ( Protophyllocladoxylon owensii [116]) all present. All of the angiosperms present are referable to Magnoliopsida, with nine morphotypes referable to Fagales [111,113], and one to Laurales ( Lovellea wintonensis [117]).…”

The palaeoenvironment of the Upper Cretaceous (Cenomanian–Turonian) portion of the Winton Formation, Queensland, Australia

“…Instead we compared different kinds of fossils at one site: pollen, wood and leaf impressions. For example, at QM L311, all of the wood is assigned to the podocarp, Protophyllocladoxylon owensii ( Fletcher et al., 2014a ) and in agreement, 87% of the pollen is referred to Podocarpaceae ( Dettmann, Clifford & Peters, 2009 ). Pollen is considered to represent the diversity of the palaeo-landscape, even if not at a 1:1 ratio due to differences in pollen syndromes and low morphological distinctiveness within some groups ( Birks et al, 2016 ).…”

“… This map of Australia shows the outcropping of the Winton Formation in Queensland (in grey), focusing on the fossiliferous area around Winton (enlarged; adapted from Fletcher et al, 2014a ). Coloured symbols indicate sites dated by detrital zircons (dark blue/red) or sites stratigraphically correlated to sites dated by detrital zircons (light blue/pink) in Tucker et al (2013) and Syme et al (2016) .…”

“…Its faunal assemblage includes evidence of a diverse range of invertebrates (insects, freshwater bivalves and gastropods), along with both aquatic and terrestrial vertebrates (dinosaurs, crocodyliforms, teleosts and dipnoan lungfishes, lizards, and turtles; Thulborn & Wade, 1979 ; Thulborn & Wade, 1984 ; Dettmann & Clifford, 1992 ; Hocknull, 1997 ; Kemp, 1997 ; Hocknull, 2000 ; Molnar & Salisbury, 2005 ; Hocknull & Cook, 2008 ; Scanlon & Hocknull, 2008 ; Dettmann, Clifford & Peters, 2009 ; Hocknull et al, 2009 ; Agnolin et al, 2010 ; Molnar, 2010 ; Romilio & Salisbury, 2011 ; Dettmann, Clifford & Peters, 2012 ; Romilio, Tucker & Salisbury, 2013 ; Berrell et al, 2014 ; Fletcher & Salisbury, 2014 ; Romilio & Salisbury, 2014 ; Poropat et al, 2015a ; Poropat et al, 2015b ; White et al, 2015a ; White et al, 2015b ; Poropat et al, 2016 ; White et al, 2016 ). At least 50 macrofossil plant taxa are present, from 10 orders, showing a co-dominance of araucariacean, podocarp and cupressacean conifers with early angiosperms ( Bose, 1955 ; Whitehouse, 1955 ; White, 1966 ; Dettmann & Playford, 1969 ; Peters & Christophel, 1978 ; McLoughlin, Drinnan & Rozefelds, 1995 ; Chambers, Drinnan & McLoughlin, 1998 ; Martin, 1998 ; Pole, 1999 ; Pole & Douglas, 1999 ; Dettmann & Clifford, 2000 ; Pole, 2000a ; Pole, 2000b ; Clifford & Dettmann, 2005 ; Dettmann, Clifford & Peters, 2009 ; McLoughlin, Pott & Elliott, 2010 ; Dettmann, Clifford & Peters, 2012 ; Fletcher et al, 2014a ).…”
