Материал из Онлайн справочника
Шаблон:Infobox rockunit The Dukamaje Formation is a geological formation in Niger and Nigeria whose strata date back to the Late Cretaceous. Dinosaur remains are among the fossils that have been recovered from the formation.[1] A wealth of Mosasaur fossils have also been recovered from this formation, particularly from the area around Mt. Igdaman.[2]
