Hațeg Island

Hațeg Island is a large offshore island that was once 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 Adriatic Plate's northwest movement across the Piemont-Liguria Ocean towards the end of the Cretaceous. 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 vegetation, for example, was of course entirely distinct from today, as was the fauna.

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. Nopcsa's theory of insular dwarfism—also known as the island rule—is today widely accepted.

The Island's Resurrection
In the year 1993, some scientists and zoologists have time traveled to the island about 80 million years ago and studied all of the known animals and plant species that lived on the island. Due to the popular demand on ressurecting the island back from extinction, in 2007, people had used a similar-sized Hațeg Island-sized time portal and swept the island to 1400's, fortunately, none of the plants or animals that got their got killed or injured during the process. The island is now found off the coast of California close to San Franscico and is now part of North American landmasses.
