  Abstract:  The paper is focused on new micropalaeontological data from the Triassic succession of Krížna and High-Tatric units in the Tatra Mts. Benthic foraminifera species were determined from the Anisian−Norian succession of the Krížna Unit and the Anisian succession of the High-Tatric Unit. In the later, calcareous algae species were also found. In mentioned Triassic successions, most of genera were described for the first time, while the others were found in new locations. A few of them belong to index fossils. Based on the assemblage containing calcareous algae Oligoporella species, characteristic for the Oligoporella pilosa – Phisoporella pauciforata zone, as well as the foraminifera Meandrospira dinarica, and the presence of Diplopora annulatissima, the age of the upper part of the Stoły pod Ciemniakiem section (High-Tatric Unit) is most probably Lower Illyrian. The establishment of the foraminifera species Pilamminella semiplana, Glomospirella triphonensis and Nodosaria skyphica, within the limestone of the Łysanki section and accompanying species Ophthalmidium cf. exiguum, Hoyenella gr. sinensis, Agathammina sp. and Gaudryina sp. from Żleb pod Czerwieniec and Skoruśniak sections (Krížna Unit): suggest early Anisian age. Ladinian age is indicated by the Turriglomina mesotriasica – Glomospirella kuthani/gemerica – Aulotortus gaschei praegaschei assemblage present in the dolostones of the Skupniów Upłaz and Hlúpy sections (Krížna Unit). The assemblage from dolostones of the Żleb pod Czerwoną Przełęcz (Krížna Unit) includes ?Triasina hantkeni species, which is a zone marker for the upper Norian (Sevatian) to Rhaetian succession.
