Czarna Shale Formation
Opis:: Ten ichnogenera and seven ichnospecies are described from the Czarna Shale Formation, possibly representing the Terreneuvian and Cambrian Series 2 of the Holy Cross Mountains. Moreover, five other ichnotaxa are described in open nomenclature. Phycodes circinatus,Taenidium isp., Trichichnus linearis and ?Dictyodora isp. are described from the Cambrian of the Holy Cross Mountains for the first time. The stratigraphic ranges of Trichichnus linearis and Phycodes circinatus are extended. The trace fossil assemblage and associated, sedimentological features point to deposition in the upper and lower offshore. Periodic, anoxic events may have occurred on the sea bed.

Tytuł:: New finds of Rusophycus from the lower Cambrian Ociesęki Sandstone Formation (Holy Cross Mountains, Poland)

Rusophycus
Opis:: The Ociesęki Sandstone Formation represents the Holmia-Schmidtiellus and the Protolenus-Issafeniella zones. Seven ichnospecies of Rusophycus, including Rusophycus exsilius isp. nov, are recognized in this formation. Moreover, Rusophycus ispp. A, B, C are recognized. The diagnoses for R. dispar, R. crebrus and R. magnus have been emended and the stratigraphic range of R. versans has been extended. The presence of Rusophycus dispar may suggest a palaeozoogeographical connection between the Małopolska Block, the Baltica palaeocontinent and the Laurentia palaeocontinent.

Tytuł:: Ichnology of the Cambrian Ociesęki Sandstone Formation (Holy Cross Mountains, Poland)
Autorzy:: Stachacz, M.

Tematy:: Cambrian

Opis:: Quartz arenites and wackes with intercalations of silty shales of the Ociesęki Formation were analysed in small outcrops and one core. The succession contains about forty-three ichnogenera and seventy-four ichnospe- cies, among which thirty-three ichnogenera and fifty-three ichnospecies are described by present author. The formation belongs to the Schmidtiellus-Holmia Superzone and to the Protolenus-Issafeniella Zone. Most strata are totally bioturbated. The diverse and numerous trace fossils represent the Cruziana ichnofacies in the lower part of the formation and the Skolithos ichnofacies in the upper part. A few possibly new ichnospecies of different ichnogenera have been described in open nomenclature. Sedimentary structures and trace fossil assemblages indicate that the older part of this formation was deposited on the upper offshore to lower shoreface, while its younger part was deposited on the lower to middle shoreface, where storm episodes were the main factor controlling sedimentation and the activity of benthos. The trace fossil associations studied are similar to those from the lower Cambrian in many places around the world. The ichnoassociations from the Polish part of the East European Platform and from Sweden, which represent the Baltica palaeocontinent, display the closest similarity.

Tytuł:: Trilobites, their traces and associated sedimentary structures as indicators of the Cambrian palaeoenvironment of the Ociesęki Range (Holy Cross Mountains, Poland)

Cambrian Series 2
Opis:: Enrolled specimens of trilobite species Strenuella polonica, partly preserved within their escape structures and burrows from the Cambrian Series 2 Ociesęki Sandstone Formation, are described. The specimens are interpreted as buried during storm episodes. Their occurrence in a few horizons, the presence of non-bioturbated tempestites with combined wave-current ripples and groovemarks interbedded with bioturbated beds suggest a depositional environment between normal and storm wave base. The trace fossils Monomorphichnus and some Rusophycus have been interpreted as structures formed during the storm when animal tried to take refuge. Well-preserved syndepositional Rusophycus and its different taphonomic variants are discussed. The part of the Ociesęki Sandstone Formation studied is interpreted as deposited on a lower shoreface with storm influence.
