Introduction
Marian Bordeianu is currently a PhD student at the Department of Geology, Babeș-Bolyai University from Cluj-Napoca, Romania. Marian's research will be focused on Miocene micro-vertebrates from the Moldavian and Scythian platforms from Romania, with interest in other geological ages that include vertebrate fossils, both micro and macro.

Description
  • Currently enrolled as a PhD student, the basic research that I conduct is related to Miocene microvertebrates from the Moldavian and Scythian Platforms from Romania. Also interested in studying other mostly-terrestrial vertebrates of any geological age, and invertebrates that are relevant for continental paleoenvironments.

Being one of the first dinosaurs discovered in Romania, Elopteryx nopcsai is a Paravian dinosaur species whose described material is mainly based on proximal femur fragments. All the known remains assigned to this taxon have been collected from the latest Cretaceous (Maastrichtian) deposits of the Hațeg Basin. A similar fragment was collected from...

The geology of the Apuseni Mountains and their related sedimentary basins was an ongoing challenge for the Romanian geological research. Amongst these basins, the Neogene basins Șimleu, Borod, and Beiuș stand out thanks to their geothermal and hydrocarbon potential. The structural evolution of the basement of these subsiding areas, 6 Marian Bordeia...

On the occasion of the 80th commemoration of Professor Ion Popescu-Voitești's demise, we can say with certainty that he still remains one of the pillars of the geological sciences in Romania. As one of the pioneers of this science in Romania, his numerous written contributions also include a significant number of illustrations. Among the latter the...

The aim of the BrineRIS project is to explore brines in RIS countries potential for critical metal extraction. In the frame of this project, the concentration of mineral brines in three geothermal wells located in the Beiuș Basin (northwestern Romania) was determined by analyzing the water from the wells. Until recently, no reliable trace element d...

A fish fauna originating from a limestone level of the Palaeogene sedimentary succession exposed on the northwestern side of the Transylvanian Basin (Gilău sedimentary area), belonging to the Viștea Limestone Formation, was discovered. On this occasion, we studied a lower Priabonian fish assemblage from the Leghia-Tabără area in Cluj County. Priabo...

The sedimentary rocks of the Transylvanian Basin, the largest molassic basin in Romania, range in age from the latest Cretaceous to the late Miocene. While younger ages are prevalent in the basin's central area, only a few areas on the basin's periphery expose older ages. e Paleogene Gilău sedimentary area is among the latter ones. On the surface o...

A charophyte assemblage composed of six species has been recovered from lower Oligocene deposits of the Dâncu Formation at the fossil site of Suceag (Transylvanian Basin, Romania). The assemblage is dominated by the two varieties of the species Lychnothamnus pinguis (L. pinguis forma pinguis and L. pinguis forma major). Accessory species include Ly...

In the last decade, the Upper Miocene formations from Eastern Romania have yelded a variety of vertebrate faunas that proved to be of great interest for the European terrestrial assemblages. One of the fossil localities of interest for such faunas is Fălciu - Prut 1, located in Vaslui County (Scythian Platform). Amongst vertebrate fossils such as f...

To date, in SW Transylvania, latest Cretaceous terrestrial deposits that yielded microvertebrates are known from two localities: Oarda de Jos and Petreștii de Jos. Recently, at Oarda de Jos, works for a quarry were undertaken in order to prepare the field for a new neighborhood (residential area). We continuously surveyed this quarry and, in the sp...

Moldova region is situated in the eastern territory of Romania located between the Eastern Carpathians and the Prut River. Structurally, its basement consists of Moldavian and Scythian platforms. They share three “mega-cycles” (Ionesi, 1994) or, better said, sedimentary mega-sequences. The last mega-sequence lasted from late Badenian until Quaterna...

The Gilău sedimentary area, located in NorthWestern Transylvania (Romania), has a rich history as it concerns the Paleogene terrestrial biota (Codrea and Fărcaș, 2002; Fărcaș, 2011, and references therein; Tissier et al., 2018). Amongst this terrestrial biota, charophytes (aquatic plants) constitute a part of the fossil record that is not fully und...

A moderately diverse fossil amphibian and squamate reptile assemblage, consisting of various fragmentary cranial bones, vertebrae and appendicular elements, is reported from the late Miocene (Turolian, MN 11-12) of Fălciu-Prut 1 locality. The fossil assemblage represents a lacustrine taphonomic context, where the skeletal remains reached the burial...

Pliocene formations are cropping out in Romania on extended areas that can be found mainly in the Dacian basin, but also in the Bârsei sedimentary basin, from the inner Carpathian region. Several other mastodon discoveries in the same region, such as the findings in the Pannonian basin and the related sub-basins can also be presumed to be related t...

The Oligocene fish fauna of the Romanian Eastern Carpathians is of great interest for the study of the extinct European perciform fish assemblages because their diversity and fine preservation. Amongst these deposits, some exceptional fossil localities such as the recently discovered outcrop from the Coza Valley and the well-known historical locati...

Abstract. Crocodiles are a conservative group of reptiles regarding their morphology and behaviour. Fossil representatives are hence important to be studied. In the Paleogene sedimentary area of Gilău, from the former Mănăștur limestone quarry in Cluj�Napoca, a fossil fragmentary crocodile skull was found in Priabonian rocks. This 19th century disc...
Article
Isolated pharyngeal teeth, pectoral, dorsal and suborbital fish spines were unearthed in a new outcrop located on the right bank of the Prut River, at Fălciu, Romania. They document Late Miocene aquatic ecosystems of the Dacian basin. Seven taxa were identified and described, six of them belonging to the order Cypriniformes and one to Siluriformes....
Article
We appreciate the comments of Buffetaut and Angst on our recent study of a Gargantuavis-like pelvis from the Late Cretaceous of Romania. We consider some of their points to be valid, but maintain our conclusion on the likely absence of a glycogen body in Gargantuavis and the lack of fusion of the pelvic elements in the acetabular region. Both chara...

An isolated leg bone of the chalicothere Ancylotherium pentelicum was found in the locality Pogana, in Moldavia (Eastern Romania). The ungual phalanx was unearthed from Maeotian sands. It is the first chalicothere species ever reported in Romania documenting the presence of the Schizotheriinae. The fossil, as well as the sedimentary environment of...

The small sized kentriodontid dolphin Kentriodon fuchsii, as well as an isolated indeterminate dolphin vertebra, are here reported from the new Sarmatian s.s. (late middle Miocene, latest Bessarabian) locality Fântânele (Bistrița-Năsăud District). The fossils were unearthed during some archaeological excavations carried out in the place named "La G...
Article
We describe a well-preserved pelvis from the Maastrichtian Sanpetru Formation of the Hateg Basin in Romania. The fossil closely resembles the pelvis of Gargantuavis philoinos from the Ibero-Armorican Peninsula, but differs in a smaller size and a few morphological features. It constitutes the first record of Gargantuavis outside the Ibero-Armorican...

The study of Oligocene fishes from the external sector of the Eastern Carpathians Flysch of Romania (Marginal Folds Nappe or Vrancea Nappe) started more than a century ago. During all this time the research was focused mainly on the Northern exposures of these deposits, while the southern areas remained almost neglected. The aim of this research is...
