Rusophycus. Things To Know About Rusophycus.

Isopodichnus is an ichnogenus of trace fossil.Ribbon-like in form, Isopodichnus traces were likely formed by the activity of an isopod crustacean foraging within the preserved sediment. Parallel to the bedding plane, a central furrow is flanked by two hypichnial ridges. Trails may also exhibit scratch marks and be associated with Rusophycus-like resting …English: Rusophycus (presumably R. pectinatus, i.e. Cruziana pectinata sensu Seilacher) and other trace fossils from the Gog Group (Early Cambrian), Lake Louise, Alberta, Canada.

The sculpture of Rusophycus may reveal the approximate number of legs that the tracemaker had, although striations (scratchmarks) from a single leg may overlap or be repeated.

Rusophycus latus (Fig. 9 B-D): Deep structures composed of two well-defined lobes, separated by a relatively shallow axial furrow. Trace fossil outline typically heart-shaped, but in some specimens transversally elliptical. Length/width ratio less than one.

However, the styles and quality of preservation are consistent with a (very) shallow mixed layer and the presence of a firm substrate just beneath it. In strata of Cambro-Ordovician age, exquisite preservation of relatively shallow tiers (e.g., Rusophycus and Trichophycus emplaced no deeper than 5-10 cm) is common. The mixed layer would have ...The Rusophycus-like burrow documented from the Hongjingshao Formation is relatively small in size, and is therefore, unlikely to be representative of a predation trace. Zhu et al. (2004) reported some trilobite fragments in a Fuxianhuia -type arthropod gut, suggesting that Fuxianhuia -type arthropods prey on trilobites in the Early Cambrian.Cruziana tenella from the lower Cambrian of south-central Sweden illustrates this intermittent mode of formation with a series of Rusophycus eutendorfensis leading into vertically undulating Cruziana that, at end stages of development, reflect a relatively equal depth distribution throughout the trace fossil and a great number of intergrading ...Rusophycus, a "resting trace" of a trilobite; Ordovician of southern Ohio.

Seilacher, 1970). Larger, indistinct specimens are also present. Most of the small specimens are similar to Rusophycus carleyi (James, 1885) or R. pudicus Hall, 1852. Cruziana cf. problematica and Rusophycus carbonarius are present in very-fine to fine-grained sandstone layers interbedded with dropstone-bearing mudstone in the lower section of the middle interval.
