Bakonybatrachus is an extinct genus of discoglossine discoglossid frog known from northwestern Hungary. [1]
Bakonybatrachus is known from the holotype MTM V 2010.283.1, a well preserved right ilium and from some referred isolated bones, including MTM V 2009.34.1, right maxilla, MTM V 2008.31.1, left angulospenial, and MTM V 2008.30.1, left scapula. All specimens were collected in Iharkút locality from the Csehbánya Formation in the Bakony Mountains, dating to the Santonian stage of the Late Cretaceous. The ilium suggest that Bakonybatrachus was a good jumper and swimmer. [1]
Bakonybatrachus was first named by Zoltán Szentesi and Márton Venczel in 2012 and the type species is Bakonybatrachus fedori. The generic name is derived from Bakony Mountains, in which the specimens were found, and Greek batrachus, "frog". [1]
Bombinatoridae is a family of toads found in Eurasia. Species of the family have flattened bodies and some are highly toxic.
The Alytidae are a family of primitive frogs. Their common name is painted frogs or midwife toads. Most are endemic to Europe, but three species occur in northwest Africa, and a species formerly thought to be extinct is found in Israel.
Hungarosaurus tormai is a herbivorous nodosaurid ankylosaur from the Upper Cretaceous (Santonian) Csehbánya Formation of the Bakony Mountains of western Hungary. It is the most completely known ankylosaur from the Cretaceous of Europe.
Doratodon is an extinct genus of Late Cretaceous ziphodont crocodylomorph that was once believed to be a dinosaur, that could be a sebecosuchian mesoeucrocodylian. Two species of Doratodon are known to science: D. carcharidens from Austria and Hungary, the type species; and D. ibericus from Spain.
Palaeobatrachus is an extinct genus of frogs from Europe that existed from the middle Eocene to the middle Pleistocene, spanning almost 50 million years. They were obligately aquatic, and would have not spent much time on dry land. They are one of two genera and by far the largest genus in the family Palaeobatrachidae, which are considered to be members of Pipimorpha, related to the South American-African family Pipidae, which includes the African clawed frog and Surinam toad.
Bakonydraco is a genus of pterodactyloid pterosaur from the Late Cretaceous period of what is now the Csehbánya Formation of the Bakony Mountains, Iharkút, Veszprém, western Hungary.
Achillesaurus is a genus of alvarezsaurid theropod dinosaur from the Santonian-age Upper Cretaceous Bajo de la Carpa Formation of Rio Negro, Argentina. It was named in reference to Achilles' heel, because diagnostic features are found there for these animals. The genus was a relatively large, basal alvarezsaurid, and a contemporary of Alvarezsaurus. Achillesaurus is based on MACN-PV-RN 1116, a partial skeleton including a sacral vertebra, four tail vertebrae, part of the left thighbone, shin and foot, and the left ilium. Agustín Martinelli and Ezequiel Vera, who described the specimen, performed a phylogenetic analysis and found their new genus to be an alvarezsaurid with an unresolved relationship to Alvarezsaurus and more derived alvarezsaurids. Makovicky, Apesteguía & Gianechini (2012) argued that Achillesaurus might actually be a junior synonym of Alvarezsaurus which, according to the authors, "is known from the same formation and from which it [i.e. Achillesaurus] differs trivially."
Aerosteon is a genus of megaraptoran dinosaur from the Late Cretaceous period of Argentina. Its remains were discovered in 1996 in the Anacleto Formation, which is from the late Campanian. The type and only known species is A. riocoloradensis. Its specific name indicates that its remains were found 1 km north of the Río Colorado, in Mendoza Province, Argentina.
The Albanerpetontidae are an extinct family of small amphibians, native to the Northern Hemisphere during the Mesozoic and Cenozoic. The only members of the order Allocaudata, they are thought to be allied with living amphibians belonging to Lissamphibia. Despite a superficially salamander-like bodyform, their anatomy is strongly divergent from modern amphibians in numerous aspects. The fossil record of albanerpetontids spans over 160 million years from the Middle Jurassic to the beginning of the Pleistocene, about 2.13-2 million years ago.
Iharkutosuchus is an extinct genus of basal eusuchian crocodyliform. Its fossils have been found in the Santonian-age Upper Cretaceous Csehbánya Formation in the Bakony Mountains of western Hungary.
Pneumatoraptor is a genus of small, paravian dinosaur that lived in Hungary. It is known from a single complete left shoulder girdle (scapulocoracoid) found in the Csehbánya Formation of the Iharkút locality in the Bakony Mountains of western Hungary. This formation dates to the late Cretaceous period about 85 million years ago.
The Csehbánya Formation is a geological formation in the Transdanubian Mountains of Veszprém County, Hungary. The formation dates to the Late Santonian of the Late Cretaceous. It represents a floodplain environment as opposed to the swampy lacustrine environment of the simultaneous Ajka Coal Formation, though there is complete overlap in terms of fauna. It underlies the Jákó Marl Formation, and laterally transitions to the Ajka Coal Formation.
Hungarobatrachus is an extinct genus of advanced frog, which lived during the upper Cretaceous period in what is now Hungary. It was described in 2010 from isolated ilia and tibio-fibulae recovered from the Iharkút locality in the Csehbánya Formation. This genus was named by Zoltán Szentesi and Márton Venczel in 2010, and the type species is Hungarobatrachus szukacsi. While originally interpreted as a member of Ranoidea, a later study based on new ilia and skull bones found it to be a member of Hyloidea instead.
Huehuecanauhtlus is a genus of hadrosauroid dinosaur known from the Late Cretaceous of Michoacán, western Mexico. It contains a single species, Huehuecanauhtlus tiquichensis.
Pannoniasaurus is an extinct genus of tethysaurine mosasauroid known from the Late Cretaceous Csehbánya Formation of Hungary. It contains a single species, Pannoniasaurus inexpectatus, dubbed "unexpected" because it was discovered in freshwater sediments, unlike other mosasaurs, which were marine predators. It was a medium-sized mosasaur, reaching up to 6 m (20 ft) in length and 550 kg (1,210 lb) in body mass.
Overosaurus is an extinct genus of sauropod dinosaurs, containing only a single species, Overosaurus paradasorum. This species lived approximately 86 to 84 million years ago during the latter part of the Cretaceous Period in what is now Patagonia. Overosaurus paradasorum was relatively small compared to other sauropods from Patagonia, like the saltasaurids and other aeolosaurines, estimated as approximately 10 m (33 ft). It was a ground-dwelling herbivore.
Kallokibotion is an extinct genus of stem-turtle from the Upper Cretaceous, known from fossils found in Romania. One species is known, Kallokibotion bajazidi, which was named by Franz Nopcsa after his lover Bajazid Doda. It literally means 'beautiful box of Bajazid'; Nopcsa chose the name because, in the words of British palaeontologist Gareth Dyke, "the shape of the shell reminded him of Bajazid's arse". A second undescribed species is known from the Santonian of Hungary.
Chromatogenys is an extinct genus of Scincomorph lizard from the Santonian of Hungary, containing the species C. tiliquoides. It is known from the Csehbánya Formation with the remains consisting of a partial right mandible, the name coming from the vibrant colours on the preserved specimen. The dentition is durophagous, and the animal likely ate hard shelled prey.
The Schönleiten Formation is a geological formation in Austria. Part of the Gosau Group it was deposited during the later Turonian of the Cretaceous period. It primarily consists of grey, weathered yellow shales and dense sandstone, with coal bearing shales near the base. The remains of indeterminate frogs, snakes, Tethysaurines, crocodylians and the teeth of cf. Paronychodon and other indeterminate theropod dinosaurs are known from the formation.
Aprosuchus is a genus of small-bodied Maastrichtian atoposaurid Eusuchian from the Hateg Basin, Romania.
