The teeth probably represent an attritional assemblage that could have belonged to several individuals of various sizes and ages, provided with heterodont dentition of at least five morphotypes (slender caniniform, triangular-lanceolate shaped, enlarged conical, slender conical, and low crowned). We assigned the isolated teeth to Gavialoidea based on a number of morphological characters shared with representatives of early gavialoids, known from the early-middle Eocene of western Europe or North Africa. The gavialoids from Turnu Rosu represent a new group for the Paleogene of Romania that probably reached the territory of southern Transylvania in the Middle Eocene.

The nasals are excluded from the naris and the anterior tip of the frontal forms a broad, complex sutural contact with the nasals. Diplocynodon kochi n. sp. possesses, similarly to other members of the genus, 16-17 maxillary alveoli of which the fourth and fifth alveoli are enlarged and confluent; the lacrimal is longer than the prefrontal; the ectopterygoid is situated dose to the posteriormost maxillary tooth alveoli, the dorsal margin of the infratemporal fenestra is bordered by the quadratojugal, preventing the quadrate from reaching the fenestra, and the foramen aereum is situated on the dorsal surface of the quadrate. The occurrence of D. kochi n. sp. in the Priabonian of the eastern part of Central Europe suggests that the genus was still present and probably widespread across the continent that contributed probably to its survival (at least locally) across the Eocene/Oligocene boundary.}, keywords = {new species; Paratethys; CARBONATE PLATFORM; Priabonian; Faunal diversity; Diplocynodon}, year = {2022}, eissn = {1777-571X}, pages = {411-429}, orcid-numbers = {Venczel, Márton/0000-0003-2200-3619} } @article{MTMT:32913033, title = {New data on Barbatodon oardaensis Codrea, Solomon, Venczel & Smith, 2014, the smallest Late Cretaceous multituberculate mammal from Europe}, url = {https://m2.mtmt.hu/api/publication/32913033}, author = {Solomon, Alexandru A. and Codrea, Vlad A. and Venczel, Márton and Smith, Thierry}, doi = {10.5852/cr-palevol2022v21a13}, journal-iso = {CR PALEVOL}, journal = {COMPTES RENDUS PALEVOL}, volume = {21}, unique-id = {32913033}, issn = {1631-0683}, abstract = {Surprisingly, after the Early Cretaceous taxonomic diversity recorded in Europe, which probably is largely an artifact of inadequate taxonomy and inflation of taxa, multituberculate mammals became extremely scarce in the Late Cretaceous in this continent, being reported exclusively from the uppermost Cretaceous continental deposits of the so-called "Hateg Island" in Transylvania, Romania.

In this kind of deposits numerous mastodon discoveries are recorded. As in other European regions, in Romania the usual findings refer to two mastodon species the Auvergne mastodon Anancus arvernensis and Borson’s mastodon Mammut borsoni. The first one occurred earlier, in the latest Miocene (unit MN 13) at Derşida, in Sălaj County, while for the second such early occurrence is missing in Romania. Both species co-existed in the Pliocene, this being an evidence for specific diets of each of the two, thus they had non-competitive behaviors for access to food. Seemingly, both taxa became extinct at the end of the Pliocene. A third taxon could be Mammut praetypicum, but more consistent evidence on the stratigraphy of the localities where this species is recorded in Romania is still needed.}, year = {2021}, pages = {65-82}, orcid-numbers = {Venczel, Márton/0000-0003-2200-3619} } @article{MTMT:33257673, title = {Crocodylian remains from the late Paleocene of Jibou, Romania}, url = {https://m2.mtmt.hu/api/publication/33257673}, author = {Venczel, Márton and Sabău, Izabella and Codrea, Vlad A.}, journal-iso = {NYMPH FOL NAT BIHAR}, journal = {NYMPHAEA: FOLIA NATURAE BIHARIAE}, volume = {48}, unique-id = {33257673}, issn = {0253-4649}, year = {2021}, pages = {77-108}, orcid-numbers = {Venczel, Márton/0000-0003-2200-3619} } @article{MTMT:33257309, title = {Diplocynodon: a salt water eocene crocodile from Transylvania?}, url = {https://m2.mtmt.hu/api/publication/33257309}, author = {Sabau, Izabella and Venczel, Márton and Codrea, Vlad A.}, journal-iso = {NORTH-WEST J ZOOL}, journal = {NORTH-WESTERN JOURNAL OF ZOOLOGY}, volume = {17}, unique-id = {33257309}, issn = {1584-9074}, 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 Gilau, from the former Manastur limestone quarry in Cluj-Napoca, a fossil fragmentary crocodile skull was found in Priabonian rocks. This 19th century discovery documents a new species of Diplocynodon. From the Leghia-Tabara limestone quarry, another crocodile fossil was unearthed a decade ago. The latter specimen, representing a crocodile mandible, may be associated to the same new species. The new discovery provides new characters enhancing our knowledge on that species and on the whole group. Unusual is the Eocene marine environment where the crocodile fossil originated from. As a consequence, the following questions are raising: had it been a marine taxon or a terrestrial representative that managed to get in marine environments during incursions for food, or had it been transported postmortem in the marine basin by fluvial streams? The mentioned genus probably had limited osmoregulatory capabilities, in a similar way to recent alligators, which do not possess osmoregulatory salt glands, which would keep their homeostatic equilibrium under control.}, year = {2021}, eissn = {1843-5629}, pages = {117-121}, orcid-numbers = {Venczel, Márton/0000-0003-2200-3619} } @article{MTMT:32106197, title = {A Messinian (latest Miocene) occurrence for Albanerpeton Estes & Hoffstetter, 1976 (Lissamphibia: Albanerpetontidae) at Moncucco Torinese, Piedmont Basin, northwestern Italy, and a review of the European Cenozoic record for albanerpetontids}, url = {https://m2.mtmt.hu/api/publication/32106197}, author = {Gardner, James D. and Villa, Andrea and Colombero, Simone and Venczel, Márton and Delfino, Massimo}, doi = {10.5252/geodiversitas2021v43a14}, journal-iso = {GEODIVERSITAS}, journal = {GEODIVERSITAS}, volume = {43}, unique-id = {32106197}, issn = {1280-9659}, year = {2021}, eissn = {1638-9395}, pages = {391-404}, orcid-numbers = {Venczel, Márton/0000-0003-2200-3619} } @book{MTMT:32041043, title = {Fossil frogs of the genus Palaeobatrachus (Amphibia: Anura)}, url = {https://m2.mtmt.hu/api/publication/32041043}, isbn = {9783510614202}, author = {Roček, Z. and Rage, J.-C. and Venczel, Márton}, publisher = {Senckenberg Gesellschaft für Naturforschung}, unique-id = {32041043}, abstract = {Extinct frogs of the genus Palaeobatrachus are osteologically uniform, apparently because of their permanent life in water, similar to that of pipids. This, together with the fact that some species were based on articulated, mostly compressed skeletons, while others were based on disarticulated, 3D preserved bones, caused problems with their taxonomy. Another source of taxonomic misinterpretations was found in that frontoparietals of Palaeobatrachus have a complex inner structure (upper and basal layers of compact bone separated by a layer of cancellous bone), which can be fossilised separately, leaving morphologically different imprints in matrix. To avoid such inaccuracies, we used in our taxonomic comparisons three standardised osteological units called the character modules (frontoparietal, presacral vertebral column, and synsacrum) which were defined in advance according to a unified scheme and then sought in each specimen. These three modules were assessed as an interrelated complex termed here the morphotype. Comparisons of morphotypes allowed to make reasonable conclusions even if some important diagnostic characters were not preserved. For the same reason, we assessed the development of characters, in order to restrict comparisons to fully-grown individuals. It turned out that some tiny individuals, reaching an SVL length of about 30 mm or even less, may be considered fully-grown adults, based on the complete ossification of carpals, epiphyses of the long bones, and the synsacral wings. Special attention was paid to the synsacrum, which is a complex of two or three vertebrae that fuse with each other to various degrees in different taxa. Except for Palaeobatrachus gigas, the vertebral column of Palaeobatrachus consists of nine vertebrae, the anterior two (V1+2) and posterior two (V8+9) are fused together; and V7 may remain entirely independent of V8+9, or may completely (including the transverse processes) fuse to V8+9. A large number of investigated specimens enabled the statistical evaluation of morphometric data. As a general basis for taxonomic comparisons, we first gathered diagnostic features common to all hitherto recognised species of Palaeobatrachus, in order to differentiate it from other anuran genera. Then, we reviewed all hitherto recognised species, if they were based on reasonably well preserved and accessible type specimens, trying to find those features which differentiate them from the other species. Using the above-mentioned comparisons of morphotypes, 18 species are recognised, two of them introduced as new. Several other taxa (e.g. those from the late Eocene of Kučlín, and from the late Oligocene of Enspel) remain unnamed because of the scarcity of material, or for other reasons. Comparisons of samples extending from the middle Eocene through middle Pleistocene spanning about 40 Ma also made it possible to recognise some evolutionary trends.}, keywords = {Anura, Palaeobatrachus, osteology, morphological evolution, palaeobiogeography}, year = {2021}, orcid-numbers = {Venczel, Márton/0000-0003-2200-3619} }
