Ouled Abdoun Basin

Phosphate basin in Morocco

The Oulad Abdoun Basin (also known as the Ouled Abdoun Basin or Khouribga Basin) is a phosphate sedimentary basin located in Morocco, near the city of Khouribga. It is the largest in Morocco, comprising 44% of Morocco's phosphate reserves, and at least 26.8 billion tons of phosphate.^[1]^[2] It is also known as an important site for vertebrate fossils, with deposits ranging from the Late Cretaceous (Cenomanian-Turonian) to the Eocene epoch (Ypresian), a period of about 25 million years.^[3]

The Oulad Abdoun Basin stretches from the late Cretaceous to the Eocene and contains abundant marine vertebrate fossils, including sharks, bony fish, turtles, crocodilians, and other reptiles, as well as sea birds and a small number of terrestrial mammals.^[3]^[4]

Fish

Reptiles

Dinosaurs

Late Maastrichtian dinosaurs of Ouled Abdoun Basin, including Minqaria, Ajnabia, Chenanisaurus, and several unnamed specimens

Bird fossils are common in the Basin, which includes the oldest birds in Africa.^[4] At least three orders and several families of sea birds are represented, including Procellariiformes (albatrosses and petrels, fossils assignable to Diomedeidae and Procellariidae), Pelecaniformes (pelicans and allies, fossils assignable to Phaethontidae, Prophaethontidae, Fregatidae and Pelagornithidae), and Anseriformes (waterfowl, including fossil Presbyornithidae).^[4]
