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] and turtles .[ 6] Dinosaur remains are among the other fossils that have been recovered from the formation, although none have yet been referred to a specific genus .[ 7] The lithology primarily consists of clays, fine limestones and sandy clays.[ 8] [ 9]
