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...

Located in South-Western Transylvania (Romania), Râpa Roșie was and still is a controversial outcrop for the researchers which dealt with its deposits. Several opinions about the geological age of these red beds were proposed by diverse authors. We briefly discuss here this aspect, considering that an uppermost Cretaceous age (Maastrichtian) for th...

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...

Full-text available
Among the Late Cretaceous fossil sites of Europe, only those from the so-called “Haţeg Island” in Transylvania, western Romania, are remarkable by their abundance in mammal remains. Curiously, all of them belong to a single family of multituberculates, the Kogaionidae, one of the rare families that survived the Cretaceous-Paleogene mass extinction...

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...
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...
Article
The Upper Cretaceous “Hațeg Island” is not only renowned mostly for its peculiar assemblage of dwarf dinosaurs, but also for its Azhdarchidae pterosaurs including giant specimens (e.g. Hatzegopteryx thambema) and medium-sized ones (e.g. Eurazhdarcho langendorfensis), discovered in the Hațeg and Transylvanian basins of Romania. Here, we report a new...
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...

A small, but illustrative collection of Maastrichtian reptilian teeth and bones is hosted in the Natural Sciences Branch of the Mureş County Museum. The fossils were collected by József Fikk in 1943, and probably sold to the museum by Laszlo Fikk in 1962. This collection remained practically forgotten in, never mentioned in any paper. The teeth and...

Perissodactyls are one of the major groups affected by the Grande Coupure event (Eocene-Oligocene transition) in Europe. Palaeotheriidae went almost extinct during this crisis, whereas Rhinocerotidae appeared for the first time in Europe after this biogeographical event. Knowledge on fossiliferous Eastern-European localities around this period is c...

Abundant isolated bones of fossil lizards from the uppermost Cretaceous (Maastrichtian) continental deposits of western Romania point to a previously unexpected squamate diversity in the so-called Hațeg Island. Using previously reported and recently collected material, we define here a new family of teiioid lizards. In addition, new specimens recov...

The notorious "Hațeg Island" was an insular realm in the Tethys Ocean which emerged in the latest Cretaceous, soon after the "Laramian" tectogenesis. The hard evidence concerning the specific environments documented by terrestrial deposits can be noticed in several sedimentary basins. The best studied one is the Hațeg Basin (abbreviated, HB), which...
