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). The sediment between these two Rusophycus has faint curved grooves suggesting that they were made by the same individual. Remarks. We previously (Jensen et al.

Rusophycus are created when a trilobite is stationary upon loose substrate. In filter-feeding trilobites such as Cryptolithus, the movement of limbs under the circular cephalic shield create distinctive trace fossils that mark this kind of feeding behavior, called Rusophycus cyptolithi. You can learn more about this in the section on Trilobite ...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).Cruziana and Rusophycus are commonly assumed to be trilobite trace fossils, although skeletal evidence is almost always absent from host strata.

Three ichnotaxa with ichnostratigraphic significance are here documented: Cruziana acacensis elongata, Arthrophycus alleghaniensis, and A. brongniartii.trace fossils must reflect original biological behavior of the organism. Major Concepts in the Study of Traces. 1. One organism can produce multiples traces. 2. Different organisms produce similar traces. (i.e. an ichnotaxon. ≠ a biological species) 3. It is usually impossible to know what organism (s) produced a particular trace fossil.( a ) Rusophycus radialis characterized by large size, radial scratch pattern, and well-developed coxal impressions.
