Also known as Crayfish Bay, ETRW
Where: Victoria, Australia (38.9° S, 143.5° E: paleocoordinates 76.2° S, 112.0° E)
• coordinate stated in text
• small collection-level geographic resolution
When: Eumeralla Formation (Otway Group), Late/Upper Aptian to Late/Upper Aptian (122.5 - 109.0 Ma)
• from a bed locally termed the "ETRW Sandstone," above the Anchor Sandstone
• bed-level stratigraphic resolution
Environment/lithology: channel lag; medium-grained, coarse, conglomeratic sandstone
•
•"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)."
