The Sebeș Formation is a geological formation in Romania dating to the Maastrichtian age of the Cretaceous, and laterally equivalent to the nearby Șard Formation. The base of the formation consists of claystones interbedded with sandstones and conglomerates.[1] These lithologies have preserved fossils which are part of the Hațeg Island fauna.
