Abstract

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.
