Haţeg Island was a large offshore island in the Tethys Sea during the Cretaceous period. The Tethys Ocean was a Mesozoic era Ocean that existed between the continents of Gondwana and Laurasia before the opening of the Indian The Cretaceous (kriːˈteɪʃəs, usually abbreviated 'K' for its German translation "Kreide" is a geologic period and system, reaching from the end of It was situated in an area corresponding to the region around today Haţeg, Romania. Haţeg (pronunciation in Romanian: /'hɑːtseɪɡ/ German: Wallenthal; Hungarian: Hátszeg) is a town in Hunedoara County Romania ( dated: Rumania, Roumania Maastrichtian fossils of small-sized dinosaurs have been found in the erstwhile island's rocks. The Maastrichtian is the last stage of the Cretaceous period, and therefore of the Mesozoic era. FOSSIL is a standard protocol for allowing serial communication for Telecommunications programs under the DOS Operating system.
It was formed mainly by tectonic uplift during the early Alpine orogeny, caused by the Adriatic Plate's NW movement across the Piemont-Liguria Ocean towards the end of the Cretaceous. Tectonic uplift is a geological process most often caused by Plate tectonics which increases elevation The Alpine orogeny (sometimes also called Alpide orogeny) is an orogenic phase in the Tertiary that formed the mountain ranges of the Alpide belt The Adriatic or Apulian Plate is a small Tectonic plate carrying primarily Continental crust that broke away from the African plate along a The Piemont-Liguria basin or the Piemont-Liguria Ocean (sometimes only one of the two names is used for example Piemonte Ocean was a former piece of Oceanic crust There is no real present-day analog, but overall, the island of Hainan (off the coast of China) is perhaps closest as regards climate, geology and topography, though still not a particularly good match.

The Hungarian paleontologist Franz Nopcsa theorized that "limited resources" found on the island commonly have an effect of "reducing the size of animals" over the generations, producing a localized form of dwarfism. Baron Franz Nopcsa von Felső-Szilvás (also Baron Nopcsa von Felsö-Szilvás, Baron Nopcsa, Ferenc Nopcsa, Nopcsa Ferenc, Baron Nopcsa's theory of insular dwarfism — also known as the island rule — is today widely accepted. Insular dwarfism is the process and condition of the reduction in size of large animals – almost always Mammals – when their gene pool is limited to a very small environment Foster's rule (also known as the island rule) is a principle in Evolutionary biology stating that members of a Species get smaller or bigger depending on
About 9 species of dinosaurs, and one species of pterosaur are thought to have been indigenous to the island. Most of these animals were smaller versions of mainland megafauna, which became smaller due to island dwarfism, although this is certainly not the case for Hatzegopteryx which, being one of the biggest pterosaurs ever, is an example of island gigantism. Island gigantism is a biological phenomenon where the size of animals isolated on an island increases dramatically over generations Among them are included:
- Hatzegopteryx thambema, a pterosaur
- Rhabdodon priscus, an ornithopod
- Telmatosaurus transylvanicus, a hadrosaur
- Struthiosaurus transylvanicus, a nodosaur
- Magyarosaurus dacus, a titanosaur
- Elopteryx nopcsai, a theropod
- Megalosaurus hungaricus, a theropod
