Where: Western Australia, Australia (32.1° S, 115.9° E: paleocoordinates 34.1° S, 114.8° E)
• local area-level geographic resolution
When: Ascot Formation, Late/Upper Pliocene (3.6 - 2.6 Ma)
• STRATIGRAPHIC RELATIONS: Unconformably overlies Albian-Cenomanian Osborne Fm (Cockbain 1980). Minor transitional units (Balme 1980) separate the top of the Ascot Fm from both the Bassendean Sand and the Guildford Fm (Low 1971; Playford et al. 1976) THICKNESS: Approximately 20 m in figure well logs. AGE: Extended discussion of age in text (Kendrick et al., 1991), but generally regarded as Late Pliocene on the basis of molluscan and foraminiferal biostratigraphy, well-dated presumed correlatives and the age of bounding units. Correlated to Darragh's (1985) Molluscan Assemblage XVIII. STRATIGRAPHIC POSITION: From "younger" Ascot Formation, presumably lower in the stratigraphic succession, or encountered in shallow wells further down dip.
