Rusophycus

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 ….

B3: Rusophycus. See also Clarkson (1998, fig. 11.15b) and PaleoBase 1.0. Rusophycus is often described as a trilobite resting trace. What is the stratigraphic range of Rusophycus? What other organisms could have made Rusophycus? Rusophycus traces were also produced by trilobites digging for prey (see papers by Jensen [1990] and Brandt et al ...

The presence of scarce Rusophycus in the same horizon and abundant Rusophycus and other trilobite-related trace fossils about a half-meter above the level with "T." pedum, suggest a stratigraphic position no lower than the Rusophycus avalonensis Ichnozone, which is located above the "Treptichnus" pedum Ichnozone (Narbonne et al., 1987).The present assemblage in the Nagaur Sandstone is represented by Rusophycus carbonarious, Rusophycus didymus, Cruziana fasiculata, Cruziana cf. salomonis, cf. Isopodichnus isp, ...A predatory Rusophycus burrow from the Cambrian of southern New Brunswick, eastern Canada ...Skclithos, Monocraterion, and Rusophycus have been identified. Horizontal tubes on bedding planes are the most common trace fossils. Large vertical tubes containing smaller Skolithos tubes and bedding deflected downward in a cone-in-cone fashion were formed by anemones moving upwards in their dwelling tubes. Inarticulate brachiopods are present ...

Rusophycus comprises several ichnospecies, including 21 listed just for the lower Cambrian (Mángano and Buatois, Reference Mángano and Buatois 2016); its type …Recurring associations of the trilobite ichnogenus Rusophycus with various "worm" burrows suggest an interaction between the two tracemakers, specifically, capture of the worm by the trilobite. An exceptional ichnofossil from the Upper Ordovician of southwestern Ohio shows characters consistent with previously described "trilobite hunting burrows" from Cambrian and Silurian strata.Rusophycus is a trace fossil ichnogenus allied to Cruziana. Rusophycus is the resting trace, recording the outline of the tracemaker; Cruziana is made when the organism moved. The sculpture of Rusophycus may reveal the approximate number of legs that the tracemaker had, although striations from a single leg may overlap or be repeated.Ab stract: In gen eral, the trace fos sil Rusophycus, pre served as a con cave-up ward struc ture on the top of a bed, is con sid ered to be a fos sil ized mark ing, made by a trace maker.

Neoichnological study and comparison of these bioturbation structures with the fossil record allow associating them as Cruziana- and Rusophycus-like traces, i.e. traces with features very similar ...The late Dr. Osgood was a pioneer in studying trace fossils of the Cincinnati arch. This specimen is from the Upper Ordovician Kope Formation in northern Kentucky. It is Rusophycus subangulatum. Characterized by deep rusophycus like cruziana, Osgood says "such long cruziana-like burrows are not common in the Cincinnatian".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 … ….

Rusophycus occurs as single or multiple impressions. Some examples of multiple-Rusophycus assemblages are clearly the result of the activity of a single animal (e.g., serially arranged impressions of the same …
