The Cretaceous macrofloras of Romania are mainly preserved as compressions in several basins of the South Carpathians (Ha?eg, Rusca Montan?, and Ruc?r basins), Transylvania (Transylvanian Basin) and Dobrogea (Babadag Basin), with insignificant occurrences in the East Carpathians. Preservation of the Romania Cretaceous flora is generally poor, as the plant compressions usually lack cuticles or in situ spores and pollen. The ages of these floras range from the Cenomanian up to the Maastrichtian, and their biodiversity encompasses pteridophytes (horsetails and ferns), gymnosperms (conifers) and angiosperms (monocotyledonates and dicotyledonates). From the palaeophytogeographic point of view, the Romanian Cretaceous floras belong to the European Province of the Eurasian Region, occurring along the northern frame of the Tethys realm. The only coal flora was discovered in the Rusca Montan? Basin, while the rest of the Romanian Cretaceous floras are allochthonous floras preserved in clastic sediments.
