Mammut Borsoni (Hays 1834) From The Early Pliocene Of Husnicioara (Mehedinţi District, Romania), Vlad Codrea, Florina Diaconu
Studia UBB Geologia
A mastodon tooth has been found at Husnicioara coal open pit, in Mehedinţi district (southwestern Romania). It originates from the Lower Pliocene (Dacian) gravel and sand deposits lying just above the coal bed IV, mined in this quarry. The tooth exposing zygodont features undoubtedly belongs to Mammut borsoni (“Borson’s mastodont”). Although this species is very common in the Pliocene vertebrate faunas from this part of Europe, until now it was missing from the Lower Pliocene (Dacian) assemblage’s lists in our country.

Three species of agglutinated foraminifera from Cretaceous deep-water deposits that have been described as trochamminids are here transferred to the genus Ammogloborotalia ZHENG, 2001. These species are Trochammina abrupta GEROCH, 1959; Trochammina quinqueloba GEROCH, 1959, and Ammoanita globorotaliaeformis Gradstein and Kaminski, 1999. A fourth species, Ammogloborotalia sp.1, which is probably a new species from the Turonian of the southern East Carpathians of Romania is reported here for the first time. We hereby extend the known stratigraphic range of the genus Ammogloborotalia to the Late Jurassic (Tithonian).
Uppermost Jurassic-Lower Cretaceous Carbonate Deposits From Fara San Martino (Maiella, Italy): Biostratigraphic Remarks, Roberta Bruni, Ioan I. Bucur, Alain Preat
Uppermost Jurassic-Lower Cretaceous Carbonate Deposits From Fara San Martino (Maiella, Italy): Biostratigraphic Remarks, Roberta Bruni, Ioan I. Bucur, Alain Preat
Studia UBB Geologia
The Uppermost Jurassic-Lower Cretaceous limestone succession in the Maiella region of Italy has been investigated in a profile covering more than 400 m stratigraphical thickness at Fara San Martino. The succession mainly consists of peritidal limestones, intertidal and supratidal sequences being dominant, together with subtidal lagoonal facies. As a consequence, the microfossil assemblages are generally poorly developed, Microfossils occur within the subtidal lagoonal facies of this suite of restricted sediments. This feature led us to recognise five informal biostratigraphic intervals, which are facies related – instead of biozones, each of the intervals being characterized by specific micropaleontological associations. The occurrence …
Biostratigraphy Of The Cretaceous Deposits In The Western Transylvanides From Ampoi Valley (Southern Apuseni Mountains, Romania), Ramona Balc, Erika Suciu-Krausz, Florin Borbei
Biostratigraphy Of The Cretaceous Deposits In The Western Transylvanides From Ampoi Valley (Southern Apuseni Mountains, Romania), Ramona Balc, Erika Suciu-Krausz, Florin Borbei
Studia UBB Geologia
The present study is an approach of the issues related to the biostratigraphy of the Western Transylvanides. The research provided exact age data for the Feneş Formation, Valea lui Paul Formation, Bozeş Formation and Râmeţi Formation. The age of the formations was established based on the calcareous nannoplankton assemblages in Barremian-Campanian range. The lithological features together with the new age data allowed us to modify the boundaries between formations; accordingly the knowledge on the structure of South Apuseni Mountains required changes, too. The new data also imply the modification of the existent geological maps of the region. Based on the …
