Itombe Formation, Geological formation in Bengo Province, Angola.
The Itombe Formation is a geological unit in Bengo Province comprising multiple rock layers including shale, limestone, siltstone, and sandstone stacked over considerable depth. These varied layers formed in an ancient marine basin and provide a record of changing environmental conditions over geological time.
The formation was initially assigned to the Turonian age, but researchers later determined it dates to the Coniacian stage of the Late Cretaceous. This chronological revision helped scientists better understand how marine conditions evolved in this region during that period.
Local scientists study the formation to understand the marine environments and biodiversity patterns during the Late Cretaceous period in Africa.
This location is mainly accessible to professionals like geologists and energy researchers conducting drilling and sampling work. Visitors should know this is a scientific site where field research safety protocols are strictly observed.
Within the Tadi Beds locality, researchers discovered Angolatitan adamastor fossils, the first documented dinosaur record from Angola. This finding was scientifically important as it revealed the region hosted large herbivorous reptiles during the Cretaceous.
