Cercidiphyllum crenatum (Unger 1850) R. Brown 1935 (Magnoliophyta, Cercidiphyllaceae Engl.) is reported from the Badenian coal-bearing deposits of the Bozovici Basin, South Carpathians. Although it is a common species in the European Mio-Pliocene deposits, Cercidiphyllum crenatum is a rare species in the Romanian fossil flora, as it was previously...

Further revisions and detailed determinations are made for the plant fossil assemblages discovered in the Middle Miocene deposits of Ciocadia village, South Carpathian Foredeep. Arcto-Tertiary geofloristic elements are certified, namely Berberis sp., B. coloradensis, Ulmus pyramidalis, U. parschlugiana, and Zelkova zelkovifolia. The macroremains of...

The association of macro- and microflora founded in the outcrop from Stan hill; Hill is of the Basarabian age. It consists of 12 taxa of macroflora and 66 palynological taxa. Ther was observed a domination of monocotyledonous angiosperms represented by Typha(among the macrofloristic taxa), the Daphnogene gender being for the first time mentioned in...

A semi-quantitative evaluation method has been developed to map integrated fossil plant records (leaf, fruit, and pollen assemblages) in terms of zonal vegetation. It incorporates taxonomy, physiognomy, and autecological features of the fossil plants. To derive vegetation types, the final stage of this method involves a quantitative evaluation. The...

A recently developed semi-quantitative methodology for assessing Neogene zonal vegetation evolu-tion is applied to 19 Miocene/Pliocene plant localities/levels with at least two different organ assemblages. The results obtained from the different organ assemblages at each site are compared in order to test the validity of the applied method. The zon...

The digital elevation model (DEM) helps to express Neogene landscapes and vegetation on palinspastic maps with reconstructed orography. To reconstruct ancient vegetation cover, basic zonal vegetation formations and their characteristics have been defined based on diversity and proportions of zonal woody evergreen, deciduous, sclerophyllous and legu...

The article is based on a new discovered fossil flora, the flora of the Morilor Valley, located in the southern part of the Forecarpathian Basin (Central Paratethys area, southwest Romania). The plant remains are composed mainly by leaves and winged fruits imprints. The analysis of the fossil plant assemblages permitted a paleoenvironmental reconst...

The exploitation of coals in the querries from Oltenia produces some dislocations and degradetions of soils in very wide areas. The reserches made by authors has indicated that the clays between coals bed has bigger contents of P2O5 than dislocated spois and K2O and free humic acids contents are equal or evan bigger than regular soils from romania....

From the Middle Romanian lacustrine deposits of the Oltenia province, the authors describe the youngest fossil flora known until now in Oltenia. The inventory of the fossil flora includes the following taxa: Taxodium dubium, ?Platanus platanifolia, Ulmus laevis, Quercus roburoides, Q. cf. muehlenbergii, Carya serraefolia, Acer cf. tricuspidatum and...

1. Plante și amoniți în Jurasicul superior de la Lacu Roșu cantonate în depozitele detritice ale "Formațiunii cu Acanthicum". (D. Grigore, S. Iamandei, V. Paraschiv). 2. Valoarea știițifică și "economică" a zăcământului fosilifer din Jurasicul superior de la Lacu Roșu ("Formațiunea cu Acanthicum" - Hăghimaș). (D. Grigore). 3. Paralelă între activit...

Three fossil floras are investigated based on leaf-, seed-and fruit remains from the Oltenia region (west of Dacian Basin, Romania) correlated to the Upper Badenian-Middle Sarmatian (Upper Miocene). The palaeobotanical determinations are based on morphological analyses. We describe some fossil taxa never found in Oltenia and few new discovered in R...
