The following trace fossils have been recognised in the Lower Muschelkalk of Raciborowice Gorne (North Sudetic Synclinorium, SW Poland): Archaeonassa fossulata, Balanoglossites triadicus, ?Gastrochaenolites isp., Lockeia isp., Palaeophycus tubularis, Palaeophycus isp., ?Planolites beverleyensis, P. montanus, Planolites isp., ?Protovirgularia isp., Rhizocorallium commune var. auriforme, R. commune var. irregulare, R. jenense, Skolithos linearis, Thalassinoides suevicus and Trypanites weisei. Coprolites and an unidentified trace fossil A are also described. The trace fossils allow the discrimination of five ichnoassociations in the Raciborowice Gorne section: (IA 1) Rhizocorallium- Pholeus, (IA 2) Rhizocorallium-Palaeophycus, (IA 3) Thalassinoides, (IA 4) Trypanites-Balanoglossites and (IA 5) Planolites-Palaeophycus. The Lower Muschelkalk succession was deposited on a shallow carbonate ramp affected by frequent storms. Deposition commenced with sedimentation in a restricted lagoon on the inner ramp with a short episode of sabkha formation. It continued on the middle and outer ramp and then on a skeletal shoal of the outer ramp and in an open basin. Ichnoassociation IA 5 is related to a maximum transgression that commenced with the deposition of the Spiriferina Bed and which probably marked the opening of the Silesian-Moravian Gate. The basin underwent two shallowing episodes, as evidenced by ichnoassociations IA 3-IA 4, resulting in the formation of hardgrounds. Bathymetric changes in the Raciborowice Gorne section correspond well with a general transgressive trend in the Germanic Basin.

A trace fossil associated with its assumed in situ maker, a holaspid specimen of the trilobite Agraulos ceticephalus (Barrande in Notice préliminaire sur le Systême Silurien et les trilobites de Bohême, Leipzig, 1846), is reported from the middle Cambrian Buchava Formation (Drumian Stage) of the Skryje-Týřovice Basin, Czech Republic. The ichnofossil is preserved on the surface of a mudstone, behind the posterior part of the intact trilobite exoskeleton; this natural association is interpreted as mortichnia. Possible mode of life and feeding strategy of the trilobite genus Agraulos are discussed. For the association of a fodichnion with its producer preserved in situ (atop, in, or at the end of its trace fossil), the designation fodichnial association is proposed.

Previously published biostratigraphical subdivisions of the "middle" Cambrian succession of the Příbram-Jince Basin in the Barrandian area are summarized and a modified subdivision of twelve biozones proposed. Nine of the biozones are delimited by the first appearance of the eponymous species; five of these are interval zones and four are taxon-range zones. The youngest stratigraphical levels of the fossiliferous sequence in the Litavka River Valley, which lack any characteristic taxa, are assigned to one assemblage zone that is subdivided into two levels defined by the presence of two trilobites and two lingulate brachiopods. The Kodymirus vagans, Hypagnostus parvifrons and Dawsonia bohemica zones, and the Barren interzone between Paradoxides (Eccaparadoxides) pusillus-Paradoxides (Paradoxides) paradoxissimus gracilis, are newly established; the other zones are redefined or the earlier definitions retained.•
