Name : Rusophycus & Cruziana Age : Ordovician Find spot : Erfoud , Morocco Size of slab: 29 x 23 x 2 cm Weights : 1975 gr This slab is as found. It is all-natural and it has no kind of manipulation, dye, or anything else added. Cruziana (moving trace) and Rusophycus (resting place) are both very detailed.The present paper records, for the first time, trace fossil assigned to the ichnospecies Rusophycus versans from Furongian (Upper Cambrian) strata as exposed at Wiśniówka Wielka quarry,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 ...

Similarly, some ichnospecies of Cruziana and Rusophycus may occur in brackish-water settings, expanding the environmental range of application of Cruziana stratigraphy (Mángano and Buatois, 2003) beyond its more typical shallow-marine application (see Section 4.2).

Palaeophycus and Planolites were ...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 traces.Rusophycus and Cruziana, most likely associated with a trilobite, from the Lower Ordovician, Katoua Formation of Ouzina, Morocco.
