Abstract
A new find of terrestrial plant Equisetites cf. lyellii is reported from the Early Cretaceous of Slovakia. It comes from the Mráznica Formation of the Rajec Basin in Fatricum, Zbyňov locality, Rajecké Teplice (Žilina district). The presence of a 53 mm long horsetail axis provides good evidence of terrestrial environments during sedimentation of the studied strata. According to our interpretation, such a plant strongly indicates a moist to wet habitat (even swampy environments) on the presumed dryland from where it was transported. This dryland could represent an isolated unknown small island(s) in the vicinity, or the Vindelician-Bohemian Massif that was active as a dryland for the entire period of time from the Triassic through the Late Cretaceous. However, the exact palaeogeographic position of the Fatricum during the Mesozoic in relation to the Vindelician Landmass is not entirely clear, and such an interpretation needs a bit of caution.
期刊介绍：
Palaeobiodiversity and Palaeoenvironments is a peer-reviewed international journal for the publication of high-quality multidisciplinary studies in the fields of palaeobiodiversity, palaeoenvironments and palaeobiogeography. Key criteria for the acceptance of manuscripts are a global scope or implications of problems on a global scale significant not only for a single discipline, a focus on the diversity of fossil organisms and the causes and processes of change in Earth’s history. The topics covered include: Systematic studies of all fossil animal / plant groups with a special focus on palaeoenvironmental investigations, palaeoecosystems and climate changes in Earth’s history, environment-organism interaction, comparison of modern and ancient sedimentary environments, palaeoecology and palaeobiogeography.
