    Studzianna well core (Triassic-Jurassic) from the Holy Cross Mts region were investigated. Fossil plants from the genus <i>Neocalamites</i> (Equisetales) were found mainly in the Triassic sediments. Fragments of Ginkgoales and Czekanowskiales and Coniferales were determined mainly from the Lower Jurassic. The Lower Jurassic microflora consists of sporomorphs from Bryophyta, Equisetales, Lycopodiales, Filicales from the family Cyatheaceae or Dicsoniaceae, Pteridospermophyta from Caytoniales, Ginkgoales or Cycadales or Bennettitales, Coniferales from the families Taxodiaceae, Pinaceae and Cheirolepidiaceae. Palynofacies have mainly terrestrial character and confirms earlier opinion (Karaszewski 1962, Pieńkowski 2004) of the prevailed terrestrial origin of the Lower Jurassic (Hettangian-Sinemurian) sediments from the Holy Cross Mts region.
