In Beceten Formation
Geologic formation in Niger
From Wikipedia, the free encyclopedia
The In Beceten Formation, also Beceten or Ibecten is a Coniacian to Santonian geologic formation in the Iullemmeden Basin of Niger. It has yielded a diverse fauna and some angiosperms.[1] Among others, it has yielded polypterifoms,[2] urodeles,[3] anurans,[4][5][6] and turtles.[7] Dinosaur remains are among the other fossils that have been recovered from the formation, although none have yet been referred to a specific genus.[8] The lithology primarily consists of clays, fine limestones and sandy clays.[9][10]
