Rezumat

The fossil woods are widely known from continental deposits from all around the world, ranging in age from Devonian to Pleistocene. Such fossils provide insights into the evolution of vascular plants and palaeoclimate. Coals are mainly generated by wood material. In Romania, the fossil woods are quite widespread in the Carboniferous-Pleistocene continental formations in the timespan. One of the most important sources of fossil wood is the Petroșani Basin, an Oligocene coal-bearing basin in Romania and an important coal producer for more than 150 years. The Petroșani Basin is an Alpine intramontaneous basin from the South Carpathians, formed during the Laramian tectogenesis. Bordered by promontories of the Getic Nappe and of the Danubian Units, it consists of continental-marine deposits sedimented between Oligocene-Middle Miocene, with five sedimentary horizons. The Horizon no. 2 is the richest in terms of fossil diversity such as foliage compressions-impressions, woods, fruits, seeds, spores, and pollen or other types of fossils such as numerous invertebrate remains and macro- or microvertebrate fossils. The fossil woods can only be found in the deposits of the Horizon no. 2. The fossil woods were studied for the first time by Iustinian Petrescu in 1971 who described one single species of Sequoioxylon gypsaceum (Goeppert) Greguss. Systematic researches of fossil woods of the Petroșani Basin, were conducted in the last years, when a large variety of Cupressaceae woods were collected.
