  In Beceten Formation (Niger) | |
The In Beceten Formation, also Beceten or Ibecten is a Coniacian to Santonian geologic formation in the Iullemmeden Basin of Niger. Dinosaur remains are among the fossils that have been recovered from the formation, although none have yet been referred to a specific genus. [1] The lithology primarily consists of clays, fine limestones and sandy clays. [2] [3]
The following fossils have been reported from the formation: [4]
- Fish
- Reptiles
- Amphibians
- Flora
