• "The ETRW Sandstone is interpreted as a deep (>25 m) fluvial channel deposit with thinning-up of the bedding and fining-up of the grain-size indicating deposition by lateral accretion"

• The Eumeralla deposits accumulated in a braided fluvial system and is dominated by multi-storey sandstone packages reaching in excess of 100 m thick. Where complete fluvial cycles are present, they consist of a series of channel-fill sands that fine upwards and grade into mudstone-dominated floodbasin units, commonly containing thin sandstone beds and coal seams. The bases of these cycles are marked by scoured surfaces and contain mudstone rip-up clasts, plant remains including large logs, and isolated bones of freshwater and terrestrial tetrapods and invertebrates

•"The lower part of the ETRW Sandstone consists of overlapping, low-angled, large-scale trough cross-beds of medium- to coarse-grained sandstone (Figs. 2, 3 and 5). Some troughs are up to 10 m wide. The large-scale trough cross-beds extend upwards to at least half of the unit thickness. Many of the troughs in the basal few metres of the unit are scoured and infilled with, or floored by matrix-supported conglomerate, variably comprising medium to coarse sand grains, ‘grit’ (very coarse sand to small pebble size quartz and feldspar) with mica flakes, rounded mudstone rip-up clasts (typically up to 10 cm, and rarer clasts up to 25 cm), compacted, coalified/carbonized, river transported tree limbs/branches and logs (up to 1 m diameter and some up to 5 m in length) and tree stumps with root bases and attached soil (Fig. 3). The trough cross-beds pass up into climbing rippled beds of medium to fine-grained sandstone and interbedded, very fine-grained sandstone and siltstone layers at the unit top. Some layers show bioturbation (infilled burrows). Associated and isolated fossil vertebrate remains have been excavated from infilled scours within the basal 2 m of the ETRW Sandstone (Figs. 3 and 5)."
