Sample name: QML796 (Horizon A7)

Lithology: siliciclastic (mixed)

Taphonomic context: fluvial deposit

Habitat comments: "The modern Kings Creek catchment is fed from the east by shallow, ephemeral watercourses".
The QML796 deposit contains both high-velocity lateral accretion (channel) and low-velocity vertical accretion (overbank) deposits with three highly fossiliferous horizons".
"Horizon A7 is the basal fossiliferous unit, and represents a lag and bar deposit in a main channel. Upwardly, the unit passes into clay-silt-rich overbank deposits".
"Taphonomic data suggest that most of the identifiable material was accumulated and transported into the deposit from the surrounding proximal floodplain, with the small size of the palaeocatchment precluding any long distance transport of the material".

Life forms: rodents, other large mammals, other small mammals, birds, lizards, snakes, turtles, other reptiles, frogs, fishes, snails

Excluded forms: clams, snails

Sampling methods: quarry, screenwash

Sample size: 519 specimens

Net or trap nights: 0

Basal area status: not applicable

Sampling comments: "Fossils were recovered from an exposed vertical section by in situ collecting and removal of bulk sediment to target smaller specimens".
"A 3x2 m plot was surveyed on the ground above the site, and 1x1 m quadrats were excavated in 10 cm increments using trowels and brushes".
"The excavation continued to a depth of 2.3 metres, yielding a total of 24 cubic metres of sediment and material processed".
"Excavated sediment was washed using 10 and 1 mm graded sieves".
"Specimens of Velesunio ambiguus, Corbicula australis (bivalves) and Plotiopsis balonnensis (a freshwater gastropod) were extremely common in each main fossiliferous horizon (represented by several thousand individuals), and thus, their abundance data were not recorded".
