| Lithology description: “Facies 1 consists of inclined centimetre- to millimetre-scale, tabular to lenticular, parallel-laminated and current ripple cross-laminated, light grey to buff very fine-grained sandstone. This alternates with light brown to brownish-grey mudstone and claystone locally with carbonaceous laminae…consistent with the definition of inclined heterolithic stratification. This facies is laterally extensive, is 0.3–4.7 m thick…Evidence of bidirectionality of paleocurrents is present locally, with ripple crests trending northwest and southeast. A fining-upward trend is apparent, with bedding changing gradationally up-section from flaser to wavy, to lenticular. Ironstone and claystone nodules are present in the sandstones. Trace fossils are found throughout the unit and include the ichnogenera Planolites, Palaeophychus, and Teichichnus. Most vertebrate fossils discussed here are present in this facies.” | |
