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.

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. That's why the tracks sometimes look upside down. They're actually sand casts of the tracks. The trilobite dug into the mud layer from side to side with its legs. This left a set of

Rusophycus morphology varies from unornamented, bilobed forms to forms that preserve details of ventral anatomy of the trace maker. Rusophycus occurs as single or multiple impressions.

The layer where the specimens are is really friable, which makes them really fragile to remove, so I will have to remove a large piece of rock as a support. They measure approximately 2 and 1 inches respectively.

The sizes and shapes of this trilobite and the traces match closely. Five specimens have even been found where an articulated specimen of Asaphellus appears to be directly located over a specimen of Rusophycus carleyi within a thin bed of sandstone, suggesting that the trilobite animal may have been trapped on top of a trace that it had just ...Rusophycus (Hemisphaerichnus) from the Ordovician deposits of Tuva could be traces not only of resting arthropods, but also of their coiled forms inside pits-excavation. Otherwise, impressions of sutures between the trunk segments, as well as pleural spines should have been preserved in the Tuva material.Jun 16, 2023 · The Rusophycus specimens are preserved in positive hyporelief (sensu Seilacher, 1970) in the sandy beds interbedded to the fine-grained facies (mudstones to siltstones).).

Cruziana , the feeding trace, are furrows through the sediment, which are believed to represent the movement of trilobites while deposit feeding. [34] On one slab there are two Rusophycus, both about 6 cm wide and 2 mm deep, 10 cm apart but with a similar orientation and they line up along an imaginary mid-line (Fig. 6a).
