The Hateg upper Cretaceous island concept was coined by Franz Baron Nopcsa in 1912 and has held ever since. After a review of the tectonic, sedimentological and paleontological data available, it is concluded that neither the tectonic background nor the sediment infilling make the Hateg basin a probable island site. The balanced vertebrate fauna also suggests a continental setting. The peculiar features of some of its constituents rather suggest vicariant developments along a long and not very wide mountain range, projecting from the southeast into the epicontinental seas of upper Cretaceous Europe. Hateg was not an island; it was an outpost.
