New Approach On The Saiga Antelopes (Saiga Tatarica/Borealis; Bovidae) From The Late Pleistocene And Holocene Of Crimea (Se Ukraine), Matei M. Vremir Mar 2012

New Approach On The Saiga Antelopes (Saiga Tatarica/Borealis; Bovidae) From The Late Pleistocene And Holocene Of Crimea (Se Ukraine), Matei M. Vremir

Studia UBB Geologia

The present paper is a short review of the knowledge regarding the fossil saiga antelopes from the Pleistocene and Holocene of Crimea, in the context of the general taxonomic and phylogenetic problems in question. According to the newly discovered paleontological material from the Crimean Mountain cave-sites, a new point of view is considered.

Nouvelles Contributions A La Connaisance De L'Histoire De La Vegetation Holocene Des Monts Rodnei (Carpates Orientales), Ioan TanțăU

New Contributions to the Knowledge of the Holocene Vegetation History of Rodnei Mountains. Two sequences originating from one peat bog in Poiana Ştiol (Rodnei Mts.) were pollen analyzed. The vegetation history is described since the Atlantic period. In this period the vegetation is dominated by Picea together with Corylus, Ulmus and Alnus viridis. The components frequencies of the Quercetum mixtum (Quercus, Fraxinus, Tilia, Corylus) rarely exceed 10%. The vegetation of the Subboreal period is dominated by the Carpinus and that of the Subatlantic is dominated by Fagus. Picea pollen is well represented belong the entire sequences.


Aspects De L'Histoire De La Végétation Tardiglaciaire Et Holocène Dans La Région Des Subcarpates De La Courbure (Subcarpates De Buzau), Ioan TanțăU, Maurice Reille, Sorina FăRcaș, Jacques-Louis De Beaulieu Mar 2012

Studia UBB Geologia

A Late Glacial - Holocene sequence from the Bisoca peat bog (Buzăului Subcarpathians) was studied from palynological point of view. The vegetation history, supported by 12 14C dates is described since the end of the Late Glacial. At the onset of the Holocene Ulmus became established by around 9,700 B.P.; Quercus, Fraxinus, Tilia, Corylus became established almost simultaneously by around 9,500 B.P. The local establishment of Carpinus is about 6,200 B.P. Its maximum occurred since 5,000 B.P. Fagus pollen is regularly recorded since 7,000 B.P. Its absolute dominance took place at about 2,000 B.P.


A New Late Holocene Eolianite Record From Altınkum Beach, North Cyprus, Ahmet Evren Ergi̇nal, Nafi̇ye Güneç Kiyak, Topçu Ahmet Ertek Jan 2012

A New Late Holocene Eolianite Record From Altınkum Beach, North Cyprus, Ahmet Evren Ergi̇nal, Nafi̇ye Güneç Kiyak, Topçu Ahmet Ertek

Turkish Journal of Earth Sciences

In this study, we investigated the main depositional characteristics and obtained Optically Stimulated Luminescence (OSL) ages of coastal eolianite on the north coast of Cyprus, where this occurrence had not previously been recorded. Based on EDX/SEM and XRD data and field observations, the studied eolianite that crops out between elevations of 1 m and 14 m a.s.l. is made up predominantly of quartz grains, most of which consist of medium- to fine-grained sand. The rock comprises aragonite, calcite and quartz with lesser amounts of bornite and hematite as accessory minerals. OSL ages indicated that the initial deposition of eolianite sands …


A Large Cervidae Holocene Accumulation In Eastern Brazil: An Example Of Extreme Taphonomical Control In A Cave Environment, Alex Hubbe, Augusto S. Auler Jan 2012

A Large Cervidae Holocene Accumulation In Eastern Brazil: An Example Of Extreme Taphonomical Control In A Cave Environment, Alex Hubbe, Augusto S. Auler

International Journal of Speleology

A remarkable cervid bone accumulation occurs at a single passage (named Cervid Passage; CP) at Lapa Nova, a maze cave in eastern Brazil. CP lies away from cave entrances, is a typical pitfall passage and contains bone remains of at least 121 cervids, besides few bats, peccaries and rodents remains. There is no evidence of water (or sediment) flow at the site and in general bones lack post depositional alterations and display anatomical proximity, suggesting that the majority of the remains found inside CP (mainly cervids) are due to animals that after entering the cave got trapped in the site. …
