The paper is an opinion in the discussion on the reconversion of uniform 5-year studies in geology. Our teaching experience, coupled with the opinions of our students, indicate that both models of teaching (2-level studies within the Bologna system and uniform 5-year studies) contain elements favouring the development offuture graduates. We postulate putting more emphasis on practical courses and individualized teaching methods.

Content available The oldest rocks of the Holy Cross Mountains, Poland – biostratigraphy of the Cambrian Czarna Shale Formation in the vicinity of Kotuszów

Three lower Cambrian acritarch assemblages recognized in four outcrops in the vicinity of Kotuszów in the southernmost part of the Palaeozoic inlier of the Holy Cross Mountains span a stratigraphic interval from the uppermost part of the Asteridium tornatum–Comasphaeridium velvetum Assemblage Zone to the Skiagia ornata–Fimbriaglomerella membranacea Assemblage Zone (most probably its lower part). According to current views (Moczydłowska and Yin 2012), this interval corresponds to the upper part of the Fortunian and to Stage 2 of the Terreneuvian Series. The strata yielding the oldest assemblage are thus the oldest precisely documented rocks in the Palaeozoic succession of the Holy Cross Mountains, and the oldest Cambrian rocks exposed on the surface in Poland. The current biostratigraphic scheme for the pre-trilobitic part of the Cambrian System in the Holy Cross Mountains should be modified so that it is based on local acritarch interval subzones.

Seventeen taxa of exotic trilobites representing eight families are described from the olenid- and agnostoid-dominated strata of the uppermost Cambrian Series 3 and lower Furongian alum shale facies of Sweden and from glacial erratic boulders of Denmark. Only five taxa are assigned to species level, i.e., Maladioidella abdita (Salter, 1866), Olentella rara (Westergård, 1922), Pedinocephalus peregrinus (Henningsmoen, 1957), Ptychoparia pusilla (Westergård, 1922), and Westergaardella olenorum (Westergård, 1922), whereas the others are left under open nomenclature or remain unrecognized. Most are described for the first time from the Cambrian of Scandinavia. Their affinities point to a strong connection with East Gondwana, Laurentia, Kazakhstania and Siberia. Exotic trilobites appear in the succession directly after periods of very low oxygen concentration in the Alum Shale Sea; their occurrences correspond to the ranges of agnostoid arthropods in the succession and seem to be linked to global transgressive events causing an influx of cool and/or oxygen-depleted waters onto the shelf of the Baltica palaeocontinent.

The Burgess Shale of the Canadian Rocky Mts is one of the most well-known occurrences of Cambrian strata exhibiting exceptional preservation of a soft-bodied fauna. While Lagerstätten of the Burgess Shale-type fauna have been recognized in almost all parts of the world and in all Cambrian series, the circumstances and mechanisms allowing for such a unique mode of preservation have remained enigmatic. Of particular debate has been the reconstruction of prevailing redox conditions. This brief contribution overviews the fauna and recent advances towards understanding the sedimentary and taphonomic conditions prevailing during deposition.

Deposits of the Cambrian Series 2 and 3 of the Holy Cross Mountains, comprising sandstones, and silty and clayey mudstones, are located on the Małopolska Block which is part of the Trans-European Suture Zone. Most recent geophysical data point to the proximal nature of this structural element with regard to the Baltica palaeocontinent. The trilobite assemblages are dominated by Ellipsocephalidae, generally accompanied by Holmiidae in the lower part, and by Paradoxididae in the upper part of the studied interval. They display a significant evolutionary trend, correlatable with the development of contemporary assemblages in Avalonia and Gondwana rather than those of Baltica. Discrepancies between the basement affinity and the dominant trilobites may be explained by the influence of strong larva-carrying currents from Avalonia and Gondwana.

Authorship issues are clarified, new photographic documentation is provided and emended systematic descriptions are presented for the oldest Cambrian trilobite taxa from the Holy Cross Mountains (Poland). Biostratigraphic analysis of the fauna allows correlation with the traditional Holmia kjerulfi-group Zone of Scandinavia, the Callavia Zone of Britain and Newfoundland, the lower and middle part of the Sectigena Zone of Morocco and the Marianian Stage of Spain. The trilobites display a strong biogeographic signal linked with West Gondwana and Avalonia and a suggestion is made that the TESZ margin of Baltica with the Malopolska Massif was liable to currents from those areas that distributed planktonic trilobite larvae.

Integrated analysis of trilobite and acritarch assemblages across the traditional Lower-Middle Cambrian boundary in the Holy Cross Mountains (Poland) has documented the development of both groups in this interval. Trilobite assemblages, comprising 31 taxa (13 are revised herein) dominated by the Ellipsocephalidae, change from the protolenoid-dominated in the Lower Cambrian to the kingaspidoid-ornamentaspidoid-dominated in the Middle Cambrian, and correlate well with the Agdzian Stage of West Gondwana (Geyer and Landing 2004). Correspondence to West Gondwana and Avalonia is also evident from the presence of the associated trilobite genera, Palaeolenus, Myopsolenites, Latikingaspis, Kingaspis, Latoucheia and Orodes. The acritarch assemblages, comprising 77 taxa, indicate that their main taxonomic turnover was gradual and preceded the earliest occurrence of Paradoxides spp., as in the Spanish sections. The geological succession studied in the HCM represents part of the Cambrian strata that are generally missing in Baltica.

The latest data on the chronostratigraphic standard for the Cambrian System, being the effect of the activities of the International Subcommission on the Cambrian System in the recent years, are presented. The most important change in the Cambrian stratigraphic scheme is its sub-division into four series and corresponding epochs of comparable duration. Difficulties that appear in the definition and selection of the stratotypes of particular Cambrian stages are also discussed.

New acritarch data combined with the trilobite record date most of the Wiśniówka Hill succession (western part of Łysogóry, Holy Cross Mts.) as early Furongian (early late Cambrian). The taxonomic diversity and abundance of the acritarch assemblages allow a more precise age determination than previous studies, as well as correlation with contemporary associations from Baltica, Avalonia and West Gondwana. The stratigraphic significance of trilobite trace fossils within the succession is evaluated.

Additional data on the Lower Cambrian ichnotaxa from the Holy Cross Mountains are presented. Nine ichnotaxa are described for the first time from the area, additional descriptions of three known ichnotaxa are supplied, and two ichnotaxa are shown to have extended stratigraphic ranges. Most Lower Cambrian trace fossils belong to the Cruziana ichnofacies. The high taxonomic diversity of the Early Cambrian trace fossil assemblages from the Holy Cross Mountains in comparison to the trace fossil assemblages of the Mid- and Late Cambrian of the area is confirmed.

Revision of the Late Cambrian trilobites from Łysogóry in the Holy Cross Mountains, central Poland, enabled the application of a modified version of the Upper Cambrian biostratigraphic zonation established for the Baltica palaeocontinent. The following zones and subzones were recognised: Olenus scanicus and Parabolina brevispina subzones, Leptoplastus - Protopeltura praecursor Zone, Peltura minor Zone (Ctenopyge affinis subzones), Peltura scarabaeoides Zone (Ctenopyge linnarssoni and? Parabolina lobata subzones) and the Acerocare Zone sensu lato. Biogeographically the trilobites of Łysogóry show a distinct change, from a low diversity fauna with a predominance of Avalonian forms in the early Late Cambrian, to more diversified assemblages, characterised by the constant increase to dominance of Baltic elements by the end of the Cambrian.

Thirty-seven trilobite taxa from the Upper Cambrian of the Holy Cross Mountains are described; eighteen are noted for the first time in Poland. Eleven of the previously recognised species are considered to be junior synonyms. Restorations of the exoskeleton for Aphelaspis rara (ORŁOWSKI), Leptoplastides irae (ORŁOWSKI), Peltura protopeltorum ORŁOWSKI and Trilobagnostus rudis (Salter) are provided. Large morphological variation in cephala of Parabolina (Neoparabolina) frequens (BARRANDE), observed in the literature and exemplified by the analysed material indicates that the hitherto recognised subspecies, P.(N.) frequens argentina (KAYSER) and P. (N.) frequens finmarchia (NIKOLAISEN & HENNINGSMOEN), represent one taxon. Parabolina (Neoparabolina?) lapponica WESTERGARD is most probably related to Parabolina (Neoparabolina) frequens (BARRANDE). Beltella LAKE is considered a junior synonym of Leptoplastides RAW, and the genus belongs to the Pelturinae rather than the Oleninae
