- Abstract
The green alga <italic>Palaeodasycladus</italic> was recognized in Lower Jurassic shallow-marine high-energy calcarenites of the Choč Nappe (Hronicum Domain) in the Tatra Mts in Poland. This occurrence indicates the most Northern record of <italic>Palaeodasycladus</italic> as it is known mostly from the southern part of the Western Tethys. The stratigraphic range of <italic>Palaeodasycladus</italic> (Norian, Sinemurian-Pliensbachian) and the upper Pliensbachian age of the overlying calcarenites (previous data on the basis of brachiopods) suggest that the studied part of the section was deposited during the Sinemurian-early Pliensbachian. The previous and current reports on occurrences of <italic>Palaeodasycladus</italic> allowed determination of a new northern palaeogeographic range of the shallow-marine Mediterranean biota during the Early Jurassic time.
