The continental Maastrichtian formations from Transylvania are notorious mainlyfor bearing peculiar fossils related to an island realm known as the "Hațeg Island". The thick piles of sedimentary rocks accumulated in fluvial environments. The "red beds" are in dominance. However, local peculiar environments are of interest for specific types of fossilization (plants, invertebrates or vertebrates), i.e. ox-bow lakes or fluvial temporary abandoned channels. In such deposits the fossil record can be different compared to the red beds, especially when the oxygen content was low. Case studies as the ones from Pui (Hațeg Basin) or Oarda de Jos (SW Transylvanian Basin) are exposed. The relationships of fossil taxa and these restricted environments are discussed.

AbstractIn order to constrain the age of the Upper Cretaceous continental Densuş-Ciula Formation from the Haţeg basin, South Carpathians, and correlate it with the other continental unit that occurs in the region, the Sânpetru Formation, we separated and dated by the K-Ar method biotites and amphiboles from volcanoclastic deposits. The mineral phases analysed are from two tuff layers and volcanic bombs cropping out near Rachitova village. Two tuff layers from the Densuş-Ciula Formation give early Maastrichtian ages of 69.8±1.3 and 71.3±1.6 Ma, respectively. The ages determined for the tuff layers constrain the age of deposition for the Densuş-Ciula Formation and enable further correlations with the available palaeomagnetic data from the deposits occurring along the Sibişel Valley that belong to the Sânpetru Formation. The volcanic bombs collected near to Răchitova village are andesites and dacites. The age determined by K-Ar method on hornblende separated from a volcanic bomb is 82.7±1.5 Ma, which is older than the underlying Campanian marine deposits in turbidite facies. This suggests that the volcanic bombs were re-deposited during the early Maastrichtian. Thus, the volcanics found at Răchitova have at least two origins: one type is related to an explosive synsedimentary volcanic activity, and the other type is represented by older andesitic/dacitic bombs, which most probably originate from a volcanic centre situated in the Haţeg region.
