Rusophycus.

The Trypanites Ichnofacies is characterized by domichnial borings of worms ( Trypanites ), bivalves ( Gostrochaenolites ), barnacles ( Rogerella) and sponges ( Entobia ). These are formed in shoreline rocks or in lithified limestone hard grounds on the seabed. Bioerosion traces made by gastropods and echinoids are rarely preserved in ancient cases.Is this a Rusophycus pudicum trace fossil.

Looks like it is.Cruziana and Rusophycus are commonly assumed to be trilobite trace fossils, although associated exoskeletons are almost invariably absent from host strata. In the lower Cambrian Dallas Bugt Formation of Ellesmere Island, Arctic Canada, high-energy, cross-laminated sandstones locally with dense populations of large Skolithos are overlain by thin-bedded, bioturbated, argillaceous, medium-grained ...Two specimens of the trace fossil Rusophycus bilobatus from the Silurian Rose Hill Shale of Scott County, Virginia (PRI 76851).

Therefore, the identification of Rusophycus in predominately freshwater depositional environments as preserved in the Snowy Plains Formation is not surprising. There have been numerous discussions as to the distinction between Rusophycus, Isopodichnus, and Cruziana (e.g., Bromley and Asgaard, 1979, Pollard, 1985, Keighley and Pickerill, 1996).Fig 19 uploaded by

These trace fossils, called Rusophycus, were made by trilobites digging straight down into the muddy bottom. The holes they left were filled in by sand.
