Barbatodon is a mammal genus from the Upper Cretaceous period. It lived in Transylvania at the same time as some of the last dinosaurs and was a member of the extinct order of Multituberculata. It is within the suborder of Cimolodonta, and the family Kogaionidae. The genus Barbatodon was named by Constantin Rădulescu and Petre Mihai Samson in 1986.

Magyarosaurus is a genus of dwarf sauropod dinosaur from late Cretaceous Period in Romania. It is one of the smallest-known adult sauropods, measuring only 6 m (20 ft) in length and 750–1,000 kg (1,650–2,200 lb) in body mass. The type and only certain species is Magyarosaurus dacus. It has been found to be a close relative of Rapetosaurus in the family Saltasauridae in the sauropod clade Titanosauria in a 2005 study.
Pyroraptor is an extinct genus of paravian dinosaur, probably a dromaeosaurid or unenlagiid, from the Late Cretaceous Ibero-Armorican island, of what is now southern France and northern Spain. It lived during the late Campanian and early Maastrichtian stages, approximately 70.6 million years ago. It is known from a single partial specimen that was found in Provence in 1992, after a forest fire. The animal was named Pyroraptor olympius by Allain and Taquet in 2000.
Betasuchus is a genus of theropod dinosaur which lived during the Late Cretaceous Period. Betasuchus is, besides Orthomerus, the only dinosaur genus named from remains found in the Netherlands and the only non-avian theropod found in the Maastrichtian Beds.
Bradycneme is a genus of theropod dinosaur from the Maastrichtian-age Upper Cretaceous Sânpetru Formation of the Hațeg Basin, Transylvania, Romania. The genus contains a single species, Bradycneme draculae, known only from a partial right lower leg, which its original describers believed came from a giant owl.
Elopteryx is a genus of paravian theropod dinosaur based on fragmentary fossils found in late Cretaceous Period rocks of Romania. The single species, Elopteryx nopcsai, was known only from very incomplete material until new specimens were reported in the 21st century. Balaur bondoc might represent a junior synonym of this genus.
Telmatosaurus is a genus of basal hadrosauromorph dinosaur from the Late Cretaceous of Romania. It was a relatively small hadrosaur, measuring approximately 5 m in length and 600 kg in body mass, which has been explained as an instance of insular dwarfism.
Variraptor is a genus of dromaeosaurid theropod dinosaur from the Late Cretaceous of France.
Hațeg Island was a large offshore island in the Tethys Sea which existed during the Late Cretaceous period, probably from the Cenomanian to the Maastrichtian ages. It was situated in an area corresponding to the region around modern-day Hațeg, Hunedoara County, Romania. Maastrichtian fossils of small-sized dinosaurs have been found in the island's rocks. It was formed mainly by tectonic uplift during the early Alpine orogeny, caused by the collision of the African and Eurasian plates towards the end of the Cretaceous. There is no real present-day analog, but overall, the island of Hainan is perhaps closest as regards climate, geology and topography, though still not a particularly good match. The vegetation, for example, was of course entirely distinct from today, as was the fauna.
Hatzegopteryx is a genus of azhdarchid pterosaur found in the late Maastrichtian deposits of the Densuş Ciula Formation, an outcropping in Transylvania, Romania. It is known only from the type species, Hatzegopteryx thambema, named by Buffetaut et al. in 2002 based on parts of the skull and humerus. Additional specimens, including a neck vertebra, were later placed in the genus, representing a range of sizes. The largest of these remains indicate it was among the biggest pterosaurs, with an estimated wingspan of 10 to 12 metres.
Argiles et Grès à Reptiles Formation also known as the Argiles Rutilantes Formation is an early Maastrichtian French geologic formation in the département of Var preserving the remains of several types of dinosaurs and other extinct organisms.
Gargantuavis is an extinct genus of large, primitive bird containing the single species Gargantuavis philoinos. It is the only member of the monotypic family Gargantuaviidae. Its fossils were discovered in several formations dating to 73.5 and 71.5 million years ago in what is now northern Spain, southern France, and Romania. Gargantuavis is the largest known bird of the Mesozoic, a size ranging between the cassowary and the ostrich, and a mass of 141 kg (311 lb) like modern ostriches, exemplifying the extinction of non-avian dinosaurs was not a necessary condition for the emergence of giant terrestrial birds. It was once thought to be closely related to modern birds, but the 2019 discovery of a pelvis identified as cf. Elopteryx nopcsai from what was Hateg Island shows several primitive features.
The Densuș-Ciula Formation is a geological formation in Romania whose strata date back to the Late Cretaceous. It forms part of the Hațeg Island assemblage. Dinosaur remains are among the fossils that have been recovered from the formation. It is divided up into three members, the lower member is noted for high content of volcanogenic material and is poorly fossiliferous. While the Middle member consists of silty mudstones, sandstones and conglomerates containing volcanogenic clasts and is richly fossiliferous, while the upper member consists of matrix supported red conglomerates and is poorly fossiliferous.
The Sânpetru Formation is an early Maastrichtian geologic formation. Dinosaur remains are among the fossils that have been recovered from the formation. It is located in Romania, near Sânpetru village, part of Sântămăria-Orlea commune. It forms a component of the Hațeg Island fauna.
Paludititan is a genus of titanosaurian sauropod dinosaur which lived in the area of present Romania during the Late Cretaceous. It existed in the island ecosystem known as Hațeg Island.
Balaur is a genus of theropod dinosaur from the late Cretaceous period, in what is now Romania. It is the type species of the monotypic genus Balaur, after the balaur, a dragon of Romanian folklore. The specific name bondoc means "stocky", so Balaur bondoc means "stocky dragon" in Romanian. This name refers to the greater musculature that Balaur had compared to its relatives. The genus, which was first described by scientists in August 2010, is known from two partial skeletons. Some researchers suggest that the taxon might represent a junior synonym of Elopteryx.
Oardasaurus is an extinct genus of lizard from the latest Cretaceous of Romania. It is a member of the Barbatteiidae, a group of lizards closely related to the Teiidae. At 20 centimetres (7.9 in) in length, it was much smaller than the only other named member of the Barbatteiidae, Barbatteius, which lived slightly later. Like Barbatteius, Oardasaurus can be identified by the presence of a crust of bone deposits, or osteoderms, on the roof of its skull; it differs from Barbatteius in the pattern of the sculpturing on this crust. Both Oardasaurus and Barbatteius lived in the isolated island ecosystem of Hațeg Island, having rapidly diversified into various generalist predators of small prey after their arrival on the island during the Early Cretaceous. They went extinct in the Cretaceous–Paleogene extinction event.
The Sebeș Formation is a geological formation in Romania. It is of Maastrichtian age. It is laterally equivalent to the Sard Formation. The base of the formation consists of claystones interbedded with sandstones and conglomerates. It is well known for its fossils which form a component of the Hațeg Island fauna.
