Article
Full-text available
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...
Article
Full-text available
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...
Article
Full-text available
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...
Article
Full-text available
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...
Article
Full-text available
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...

Full-text available
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...

NECLIME is an open international network of scientists working on Cenozoic climate evolution and related changes of continental ecosystems. During the past 65 million years of Earth history, globally warmer-then-present conditions prevailed in a world with almost modern paleogeography. These timespans represent promising case studies for anticipated future scenarios. Within the NECLIME network, we aim to combine data on past climate change and its environmental impact for large-scale reconstructions. NECLIME research activities comprise paleoclimate reconstructions, including atmospheric CO₂ and ecosystem analysis using multiple quantitative methods on various primarily continental proxies (plants; vertebrates; invertebrates; geochemistry and geological proxies). Complementing model studies are employed to assess connections and processes driving ocean, atmosphere and biosphere at global and regional scales. NECLIME was established in 1999 with the aim to understand Neogene trends across Eurasia. This basic idea quickly and constantly expanded to a global interest and a wider stratigaphical frame. The steadily growing NECLIME network with currently around 140 members in 34 countries is coordinated by a team of researchers and an advisory board. NECLIME holds annual conferences and workshops and administers working groups bringing forward scientific exchange, joint projects, and the integration of research data.
