An Upper Carboniferous-Lower Permian silicified wood in the Miocene conglomerate from the western Mecsek Mts. (southern Hungary)

A silicified Palaeozoic wood found in a Miocene conglomerate of southern Hu ngary is attributed to Dadoxylon stellare (UNGER) UNGER, the name in accord ance with the international Code of Botanical Nomenclature for a taxon othe rwise widely known as Dadoxylon schrollianum GOPPERT. The species named as Dadoxylon spirale by GREGUSS, which is based on a sample found in the same area and in a similar geological context, is included in the synonymy of D. stellare. Palaeoxylological data point out that the Hungarian nora evolved already in the Permian in an intricate context of tectonic microplates.
