Lattenbergites Lupu was previously considered to be a new genus of canaliculate radiolitid from the middle–upper Coniacian of Lattenberg, Germany. The re-examination of the holotype and paratypes of ...the type species L. hermi Lupu of this genus reveals diagnostic characters of Joufia milovanovici (Slišković), including the presence in the left valve of a single ring of radial canals in the calcitic outer shell layer, the canals having sub-rectangular cross-sectional shape flanking the myocardinal apparatus in the originally aragonitic inner shell layer, and a pair of tubular structures in its postero-ventral part, opposing the ‘pseudopillar’-like structures of the right valve. Therefore, we propose that Lattenbergites Lupu, is a junior synonym of Joufia milovanovici. J. milovanovici from the Malatya, Haymana-Polatlı Basins and eastern Pontides of Türkiye, as well as the Roşia Basin of Romania is also described and compared to Lattenbergites. The presence of J. milovanovici in the Northern Calcareous Alps during the middle–late Coniacian, Romania during the late Santonian to early–middle Campanian, and Türkiye during the late Maastrichtian, allows us to reconsider the palaeobiogeographic distribution of this species within the Mediterranean Tethys during Late Cretaceous time, as well as for the genus Joufia.
•The rudist genus LattenbergitesLupu, 1987, has been revised.•Its single species, L. hermi has been suggested as a synonym with Joufia milovanovici.•J. milovanovici from Türkiye and Romania is described and compared to Lattenbergites.•Palaeobiogeographic distribution and new migration routes during the Late Cretaceous are reconsidered in time and space in the Mediterranean Tethys.
The genera Balabania Karacabey-Öztemür, Branislavia Sladić-Trifunović and Klinghardtites Lupu have previously been referred to as three new canaliculate radiolitid taxa. Well-preserved articulated ...shells of these rudist genera collected from eastern Turkey, Serbia and western Romania have now been re-examined and compared with the rudist literature. They have pallial canals in the originally aragonitic inner shell layer of the left valve flanking the cardinal apparatus and a long ligamental ridge, which are the diagnostic characteristics of Colveraia Klinghardt. As a result, two species are recognised here, namely Colveraia acuticostata (Karacabey-Öztemür), encompassing all species of Balabania and Colveraia bacevicensis (Milovanović) for all species referred to Branislavia. Klinghardtites musculosus (Klinghardt) is herein regarded to be synonymous with Colveraia darendeensis Karacabey. The left valve of Colveraia acuticostata is cap like with an eccentric apex inclined gently or strongly towards the dorsal side and overlap with the commissure and has flat or rarely slightly concave radial bands. Colveraia bacevicensis is characterised by deeply concave radial bands, and longitudinal ribs and grooves of the right valve, both of which are crossed by strongly folded growth lines that overlap each other and present distinct undulations on the surface of the valve. Ornamentation of the valve and the structure of the radial bands distinguish them from Colveraia variabilis Klinghardt and C. darendeensis Karacabey. Our re-examination of specimens previously described as Balabania acuticostata Karacabey-Öztemür from eastern Serbia shows that these can be included in C. darendeensis. A biogeographical overview of species of Colveraia in the Mediterranean Tethys is presented.
•The rudist bivalve genera Balabania Karacabey-Öztemür, 1980, Branislavia Sladić-Trifunović, 1981 and Klinghardtites Lupu, 1971 have been revised and their synonymy with Colveraia Klinghardt, 1921 proposed due to the presence of the pallial canals in the aragonitic inner shell layer of the left valve and a long ligamental ridge.•Two Colveraia species are recognized: C. acuticostata (Karacabey-Öztemür, 1980) for all Balabania specimens and C. bacevicensis (Milovanović) for all Branislavia specimens.•Klinghardtites Lupu, 1971 herein regarded as synonymous with Colveraia darendeensis Karacabey, 1974.•The re-examination of the specimens previously described as Balabania acuticostata Karacabey-Öztemür, 1980 from the Eastern Serbia are also included to C. darendeensis.•We review the palaeogeographical distribution of the species of Colveraia in the Mediterranean Tethys.
The shallow-marine, mixed siliciclastic-calcareous Late Cretaceous deposits from the Apuseni Mountains have been extensively studied and compared to coeval deposits from the Alpine Gosau. The former ...are mainly represented by conglomerates, sandstones, marls, and limestones with rudists that unconformably overlie the crystalline basement and its Permo-Mesozoic cover. Our new, detailed investigations on the rudist fauna from Măgura Hill, the type locality of Pseudopolyconites hirsutus (Patrulius) and Miseia costulata Patrulius, indicate a Late Santonian–Early Campanian age for these deposits instead of an Early Santonian one as previously suggested (Patrulius, 1974). This study also mentions for the first time the occurrences of Pseudosabinia klinghardti (Böhm) and Pseudopolyconites parvus Milovanović in the rudist-bearing deposits from the Apuseni Mountains. We include their palaeontological features, as well as the ones for Pseudopolyconites hirsutus. Based on new biostratigraphic data, our study expand the stratigraphic range of Pseudosabinia klinghardti and Pseudopolyconites parvus – previously considered characteristic for the Early Campanian–Maastrichtian interval. Also we add new information on their palaeobiogeographic distribution within the central-eastern Mediterranean area during the Late Cretaceous.
•We study the rudist fauna from type locality of P. hirsutus and M. costulata.•We reveal a Late Santonian–Early Campanian age of deposits instead of Early Santonian.•Pseudosabinia klinghardti and P. parvus are first time reported in Romania.•In this study we present a taxonomic analysis of these rudist species.•We show the palaeogeography and stratigraphy of these species during Late Cretaceous.
Re-examination of the Orestella Lupu, 1982 (formerly Orestia Lupu, 1972) type material in the Geological Institute, Bucharest, Romania, revealed the need for revision of its taxonomic status. The ...holotype and paratypes of this taxon show the diagnostic characteristics of the Family Hippuritidae, not the Radiolitidae as previously indicated. This genus should therefore be transferred to the Hippuritidae. The structure of the pillars, the ligamental ridge and the outer shell layer of the right valve as illustrated by the type material point to an affiliation either with Hippurites or with Hippuritella. We discuss this assignment by taking into account the similarities with Hippurites organisans (de Montfort), Hippuritella lapeirousei Goldfuss and Hippuritella variabilis (Munier-Chalmas). The stratigraphic framework of the study material is also discussed with respect to the Upper Cretaceous successions in the Central-Eastern Carpathians of Romania.

eg Basin belonging to the Upper Cretaceous Sânpetru and Densuş-Ciula formations have been known since the beginning of the last century. Recently, two new ...exposures with a comparable fauna have been discovered in the Râul Mare valley. The sediments at these new sites, Toteşti-baraj and Năla
t

-Vad, have been compared with the sediments at the previously known Pui site. At all three sites the deposits reflect a fluvial environment with coarse-grained channel deposits channelized in fine-grained floodplain deposits with calcrete palaeosols. However, the nature of the calcrete palaeosols is different at the three sites. At Toteşti-baraj and Năla
t
̧
-Vad, hydromorphic calcic vertisols have been observed, and locally these grade into groundwater calcretes. At Pui, the calcretes are associated with redbed deposits. Considering the similar palaeogeographical situation and age of the deposits at the three sites, the difference in soil type should not be interpreted as a climatic difference but rather as a difference in the height of the palaeogroundwater table. The soils at Pui are indicative of a general semi-arid climate. Those at Toteşti-baraj and Năla
t

-Vad do not directly reflect the climate, but rather the high seasonal groundwater table. Differences in palaeohydrology between the sites are reflected in the fossil content with humidity-loving species only occurring at the Râul Mare sites.
