Cruziana.

Cruziana es un icnogénero de icnofósil -huella de actividad de un ser vivo- que corresponde a las huellas de reptación de trilobites en los fondos marinos del Paleozoico (hasta el Devónico), desde hace de unos 570 a 360 millones de años atrás. Esas arenas hoy son rocas muy duras, las cuarcitas. Es posible ver cuarcitas de apenas un centímetro hasta unos diez o quince centímetros de ...However, diverse Cruziana/Rusophycus trace fossil assemblages (Plates 13 and 14) from the upper part of the Disi Formation indicate a probable Floian (Arenig) age (Selley, 1970), so the Cambrian/Ordovician boundary must lie somewhere within these two formations. A similar suite of trace fossils (Selley, 1970) and Floian (Arenig) acritarchs …Cruziana are not the remains of an animal, but are fossil evidence of its passage.

After the Permo-Triassic extinction, Cruziana was produced by marine arthropods and freshwater arthropods. Zonneveld et al., 2002 described Cruziana-like burrows constructed by crustaceans that may better be placed within Reniformichnus (Bordy and Krummeck 2018).Trilobite Tracks Cruziana is a trace fossil consisting of elongate, bilobed, approximately bilaterally symmetrical burrows. They are usually preserved along bedding planes, with a sculpture of repeated striations that are mostly oblique to the long dimension. Trace fossils can reveal many aspects of their makers' behavior, and work on ...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.The ichnogenus Planolites frequently intersects the Cruziana. This sub-horizontal burrow made by vagile endobenthic vermiform deposit feeders represents a slightly deeper tier, occupied later than the Cruziana, but targeting the same widely distributed food resources as the trilobites that produced the Cruziana (Neto de Carvalho and Baucon 2016).21 ก.ค. 2551 ...

This association of traces is usually placed in the Cruziana ichnofacies (e.g., Ekdale and others, 1984; MacEachern and others, 2007). Ichnofacies are a characteristic grouping of trace fossils, which form in a certain range of shallow marine environmental (salinity, energy, etc.) conditions. the logical model The stratigraphic value of trilobite burrows has recently been questioned because of a seemingly Ordovician form in the Lower Cambrian of Canada.
