Stratigraphy
Geological group:Rolling Downs Formation:Winton
Stratigraphic resolution:bed
Lithology and environment
Primary lithology:"cross stratification",red poorly lithified sandstone
Secondary lithology:planar lamination,red lithified claystone
Includes fossils?Y
Lithology description: "Sediments exposed at Lark Quarry are mainly soft and fine-grained arkosic sandstones of reddish-buff colour. The sandstones for thick beds (each built of innumerable small sets of cross-bedding) and are interlayered with thin and persistent seams of indurated pinkish claystone. The dinosaur tracks are impressed in an 8-10 cm seam of finely laminated claystone that is evidently of lacustrine origin...There are no ripple-marks, rain-prints or sun-cracks, and the dinosaur tracks were impressed in firm moist mud."
Environment:lacustrine indet.
Geology comments: lacustrine origin. "Sandstones above and below the footprint bed probably resulted from periodic sheet-floods...Shrinkage of the lake had exposed extensive mud-flats marked with narrow run-off channels."
