Also known as Ichnofossil assemblage from the Lower Carboniferous Snowy Plains Formation, Mansfield Basin, Australia
Where: Victoria, Australia (37.0° S, 146.2° E: paleocoordinates 40.9° S, 141.9° E)
When: Home Station Sandstone Member (Snowy Plains Formation), Tournaisian (358.9 - 346.7 Ma)
Environment/lithology: fluvial; lithified mudstone and lithified, massive, burrowed sandstone
•Thin-bedded rippled sandstone lithofacies -Minor beds of fine calcareous and noncalcareous sandstone, with all beds < 200 m in thickness. Beds are laterally continuous with sharp boundaries, and are characterised by uniform fine to very-fine grained sandstone. Small-scale trough cross-bedding often occurs, while small-scale planar cross-bedding and discontinuous wavy lamination is also present. Mudcracks and clasts occur in some of the beds. This bed is interpreted as a moderate energy channel deposit, and assigned to the Margaritichnus ichnocoenosis. Rusophycus isp., Cruziana problematica, Palaeophycus tubularis, and Margaritichnus mansfield isp. n. were recorded.
•Thick-bedded sandstone lithofacies -Consists of very fine to fine grained, red, purple and brown sandstone with small shale lenses. The beds exhibit an over-all coarsening upwards in grain size. Occasional discontinuous wavy lamination, trough cross-bedding and small-scale planar cross-bedding occurs. Represents a high-energy river channel environment. This bed is interpreted as a high energy river channel environment, and assigned to the Cruziana ichnocoenosis. Rusophycus isp. and Cruziana probelmatica were recorded.
