The Wadi Milk Formation is a geological formation in Sudan whose strata date back to the Late Cretaceous. Originally, the formation was thought to be Albian to Cenomanian, later research has provided dating to the Campanian to Maastrichtian.[https://paleobiodb.org/classic/displayCollResults?collection_no=28491 Wadi Abu Hashim] at Fossilworks.org Dinosaur remains are among the fossils that have been recovered from the formation.Weishampel, David B; et al.

It stretches from the lower Wadi Al-Malik across the Wadi Muqaddam into the Bayuda Desert.Oliver W.M.Rauhut, A Dinosaur Fauna from the Late Cretaceous (Cenomanian) of Northern Sudan.
