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.

The Shelter above the Zegar Cave (Shelter No 388) (N 50°25’41” E 19°40’27”) is located in the Zegarowe Rocks ridge in the Ryczów Upland (southern part of the Czêstochowa Upland), municipalityWolbrom, district Olkusz. In 2009, Mrs. Jadwiga and Mr. Lucjan Wodarz found an archeological flint artifact in a type of leaf point at the slope below the Shelter. This finding allowed suspecting the presence of Palaeolithic cultural layers inside or near the Shelter. The authors’aim was to recognize the geological context of the Palaeolithic settlement of the Shelter above the Zegar Cave and its neighborhood, and in further perspective of the entire southern part of the Ryczów Upland micro-region. Four layers were discovered in the Shelter during field works (downward): I – humic silty loam, Holocene; II – loess altered by secondary soil processes during the Holocene; III – unaltered loess, dated to MOIS 2; IV – silty cave loam with limestone rubble, dated to MOIS 3. The chronostratigraphy is based on lithostratigraphy and confirmed by radiocarbon and thermoluminescence dating. An archaeological cultural level occurs in layer IV, most probably related to the shift from the Middle to Upper Palaeolithic. The sequence of cave sediments may be well correlated with numerous profiles of cave sites from the Kraków-Czêstochowa Upland.

The foraminifers belonging to the genus Pararotalia Le Calvez from the Middle Miocene of the Central Paratethys are referred to different species, eg. Pararotalia (or Rotalia) stellata (Łuczkowska, 1955; Śmigielska, 1957; Urbaniak, 1974; Szczechura, & Pisera 1986) and P. ex gr. lithothamnica (Oszczypko et al., 1992) from Poland, P. stellata from Slovakia (Holcová et al., 1996), Rotalia calcar from Hungary (Korecz-Laky & Nagy-Gellai, 1985) and Pararotalia aculeata, P. cf. aculeata as well as P. spinimargo from Romania (Popescu, 1979). It is suggested here, that all of them represent one species, ie. Pararotalia aculeata (d’Orbigny, 1846). The large infraspecific variability of this species (Pl.1, figs. 1–19), resulting in its taxonomic spliting, seems to be a consequence of ontogenetic changes, ecological modifications as well as different state of preservation. The systematic relation between P. aculeata and other so far known representatives of Pararotalia, especially those from the Neogene of theMediterranean areas, should be based on large comparative material, however P. padana Mancin, Pirini et Lanfrancini, 2000, from Pliocene of Italy, seems to be conspecific with the here discussed species.
