Where: New South Wales, Australia (30.9° S, 143.1° E: paleocoordinates 69.8° S, 116.9° E)
• coordinate based on nearby landmark
• small collection-level geographic resolution
When: Doncaster Member (Wallumbilla Formation), Aptian (125.0 - 113.0 Ma)
• Originally listed as the Coreena Formation. "The Doncaster Member of the Wallumbilla Formation is generally regarded as Early AptianeEarly Albian in age on the basis of palynological (Helby et al., 1987; Burger, 1988) and macroinvertebrate (Day, 1969) data. However, in the White Cliffs area, the unit is represented by rocks of predominantly Aptian age (see Burton and Mason, 1998). This broad age range is applied to all marine reptile fossils from the White Cliffs deposits and corresponds to the Cyclosporites hughesiie - lowermost Crybelosporites striatus spore-pollen zones, and Odontochitina operculatae-Diconodinium davidii dinoflagellate zones of Helby et al. (1987)."
