The stratigraphic value of trilobite burrows has recently been questioned because of a seemingly Ordovician form in the Lower Cambrian of Canada. Closer examination shows, however, that the Cambrian homeomorph (Cruziana pectinata n. sp.) has a significantly different scratch pattern. This raises the question whether the multiple scratches of the Ordovician Cruziana rugosa were also made by exopodites or by similarly shaped endopodites. 
Biostratigraphic precision of the Cruziana rugosa group: a study from the Ordovician succession of southern and central Bolivia
Cruziana ichnospecies have been repeatedly reported to have biostratigraphic significance. This study presents a re-evaluation of the arthropod ichnotaxa of the Cruziana rugosa Group from bio- and/or
Ichnostratigraphic correlation of Lower Palaeozoic clastics in the Kufra Basin (SE Libya)
The Lower Palaeozoic deposits in North Africa are dominated by sandstones and shales which often lack biostratigraphically useful body fossils. Trilobite burrows (Cruziana) partly fill this gap and

Late Pridoli Cruziana traces have recently been found in carbonate shelf sediments of the Ohesaare Formation on Saaremaa Island, Estonia. Cruziana isp. is interpreted here as a locomotory trace
Large, Robust Cruziana from the Middle Triassic of Northeastern British Columbia: Ethologic, Biostratigraphic, and Paleobiologic Significance
Abstract Large (up to 9.5 cm wide) and robust Cruziana ichnofossils are present in the Middle Triassic (Ladinian) Toad and Liard formations in northern British Columbia, Canada. These trace fossils
Chapter 5 Testing for palaeogeographical patterns in the distribution of Cambrian trace fossils
Abstract We examined the palaeogeographical distribution of selected Cambrian trace fossils. Astropolichnus hispanicus, Climactichnites, Syringomorpha nilssoni and early examples of Paleodictyon all
Ichnology of the Early Cambrian Tal Group, Nigalidhar Syncline, Lesser Himalaya, India
Though trace fossils have been recorded from the Tal Group of the Krol-Tal Belt by earlier workers, most of the records are at generic level only. This paper describes, in detail, 24 ichnospecies
Compaction-related style of Rusophycus preservation from Furongian (Upper Cambrian) of Holy Cross Mountains (Poland)
In general, the trace fossil Rusophycus , preserved as a concave-upward structure on the top of a bed, is considered to be a fossilized marking, made by a trace maker. The structures described from
New data on the trace fossil, Cruziana semiplicata (Furongian, Wiśniówka Sandstone Formation, Poland): origin, ethology and producer
Cruziana semiplicata Salter is a well known ichnospecies, ascribed to trilobites. Despite that, there are still contradicting views on its origin (infaunal vs. epifaunal), the ethology represented


Stratigraphic significance of Cruziana: New data concerning the Cambrian-Ordovician ichnostratigraphic paradigm
The classic Cambrian-Ordovician ichnostratigraphic paradigm originally developed in Europe is based on the assumption that Cruziana - ichnofossils presumably produced by trilobites - can be used in
Appendage morphology of the trilobite Cryptolithus and its implications
The appendages of the Ordovician trilobite Cryptolithus tesselatus are restudied, and particular reference is made to the exite branch. Details formerly borrowed from Triarthrus to complete the

Evidence of early Cambrian predation is found in trace fossils from the Mickwitzia Sandstone of VastergOtland, Sweden and an olenellacean trilobite, mainly through the presence of a cephalic impression is identified.
