A new eusuchian skull from the Maastrichtian locality of Oarda de Jos in the southwestern Transylvanian Basin of Romania represents the best-preserved known specimen of Allodaposuchus precedens Nopcsa, 1928. This new fossil allows us to clearly characterize the skull morphology of A. precedens and to reject the idea, as recently suggested, that the taxon could be considered a nomen dubium. Parsimony analysis confirms earlier phylogenetic hypotheses based on the fragmentary holotype from the Maastrichtian of Valioara in Hat¸eg Basin (Romania), as well as on putative conspecific remains from approximately coeval localities in Spain and France: A. precedens is a non-crocodylian eusuchian. However, some relevant morphological traits differ from what was previously reported for this taxon: the external naris is large and anterodorsally directed; the lateral profile of the skull is not festooned in dorsal view; the suborbital fenestrae reach the eighth alveolus; the postorbital bar is not massive and i...

About ten dinosaur nests of large megaloolithid-type eggs have been discovered in the new Maastrichtian locality of Toteşti-baraj (Haţeg Basin, Romania). This is the largest dinosaur egg nest site discovered in Romania. Teeth and other micro-remains of vertebrates such as hadrosaurs, ankylosaurs, theropods, lizards and amphibians are associated with the eggs in the sediments, reflecting the great biodiversity of the Haţeg Basin during the Maastrichtian. But the most remarkable collected micro-remains are teeth of mammals representing at present the richest multituberculate collection from the Upper Cretaceous of Europe. © 2002 Académie des sciences/Éditions scientifiques et médicales Elsevier SAS.SCOPUS: ar.jinfo:eu-repo/semantics/publishe

Terrestrial climatic data reflect variable and often conflicting responses to the global cooling event at the Eocene-Oligocene transition (ca. 34 Ma). Stable isotopic compositions of the tooth enamel of large, water-dependent, herbivorous terrestrial mammals are investigated here to better understand the European continental climate during the late Eocene–early Oligocene. High δ¹⁸OPO₄ and δ¹³C values reflect a semiarid climate and ecosystem in the late Eocene. In the west-southwest region of Europe, these conditions prevailed until at least 33 Ma, after which it became more humid. A similar change was recorded north of the Alpine thrust, but it occurred 2 m.y. earlier. The north and west-southwest regions show a significant offset in δ¹⁸OPO₄ composition between 35 and 31 Ma, indicating the influence of different air trajectories with different moisture sources (Atlantic versus Tethys). This also marks the presence of an orographic height in central Europe from the latest Eocene. After 31 Ma, a large drop in δ¹⁸OPO₄ is registered, explained by altitude-induced fractionation on meteoric water isotopic composition. The related paleoaltitude change is estimated to be 1200 m, and the uplift could have taken place along the Alpine-Dinaridic orogenic system.
