Itombe Formation
The Itombe Formation is a geological formation of the Kwanza Basin in Angola dating back to the Coniacian stage of the Late Cretaceous. The environment of deposition is shallow marine. Reptile fossils have been recovered from the Tadi beds locality within the formation, including the dinosaur "Angolatitan", the mosasaurs "Angolasaurus" and "Mosasaurus iembeensis" and the turtle "Angolachelys".The Itombe formation was formerly considered Turonian in age, but new data suggests to be Coniacian.
