NEW DISCOVERIES OF FOSSILIZED TREE TRUNKS FROM THE MIOCENE EPOCH IN THE ROZTOCZE REGION (VYNNYKY FOREST, UKRAINE)

Abstract

The petrified or fossilized tree trunks of Miocene age discovered within the Roztocze region – a transboundary Ukrainian-Polish upland – represent a unique geological and paleontological phenomenon that combines scientific, educational, and cultural value. These phytosfossils, formed under specific burial conditions and mineralization processes, allow for the reconstruction of paleoecological environments that prevailed in the region millions of years ago, as well as the identification of the taxonomic composition of Miocene flora.Due to their high degree of preservation, mineralogical diversity, and aesthetic appeal, the petrified tree trunks of Roztocze attract interest not only from scientists but also from geotourists, collectors, museum professionals, and conservationists. They serve as valuable objects for promoting geological heritage, advancing environmental education, and fostering ecological awareness among the public.However, the lack of proper protection, limited public awareness, and gaps in legal regulation often lead to illegal collection and trade of these paleontological specimens, emphasizing the urgent need for their preservation, documentation, and popularization.Research on the petrified trees of Roztocze contributes to a deeper understanding of petrification, metasomatism, and the geological history of the region. Studying their mineralogical composition, burial conditions, and spatial distribution not only enriches scientific knowledge but also lays the foundation for developing geoeducational and tourism initiatives, particularly within the Roztocze Biosphere Reserve.This article presents the discovery and description of new fossilized tree trunks of Miocene age found in the Vynnyky Forest (Lviv area, Ukrainian Roztocze). The geological and paleontological significance of the phytosfossils is discussed, along with their potential for paleoenvironmental reconstruction and the challenges of their protection and promotion. The collection of specimens, gathered by 10th-grade student O. Demandzhara, was transferred to the Paleontological Museum of Ivan Franko National University of Lviv, contributing to the expansion of the national heritage scientific collection.The study highlights the importance of preserving geological heritage and promoting geoeducational initiatives within the Roztocze Biosphere Reserve.
