List of African dinosaurs

From Wikipedia the free encyclopedia

This is a list of non-avian dinosaurs whose remains have been recovered from Africa. Africa has a rich fossil record, but it is patchy and incomplete. It is rich in Triassic and Early Jurassic dinosaurs. African dinosaurs from these time periods include Megapnosaurus, Dracovenator, Melanorosaurus, Massospondylus, Euskelosaurus, Heterodontosaurus, Abrictosaurus, and Lesothosaurus. In the Middle Jurassic, the sauropods Atlasaurus, Chebsaurus, Jobaria, and Spinophorosaurus, flourished, as well as the theropod Afrovenator. The Late Jurassic is well represented in Africa, mainly thanks to the spectacular Tendaguru Formation in Lindi Region of Tanzania. Veterupristisaurus, Ostafrikasaurus, Elaphrosaurus, Giraffatitan, Dicraeosaurus, Janenschia, Tornieria, Tendaguria, Kentrosaurus, and Dysalotosaurus are among the dinosaurs whose remains have been recovered from Tendaguru. This fauna seems to show strong similarities to that of the Morrison Formation in the United States and the Lourinha Formation in Portugal. For example, similar theropods, ornithopods and sauropods have been found in both the Tendaguru and the Morrison. This has important biogeographical implications.

The Early Cretaceous in Africa is known primarily from the northern part of the continent, particularly Niger. Suchomimus, Elrhazosaurus, Rebbachisaurus, Nigersaurus, Kryptops, Nqwebasaurus, and Paranthodon are some of the Early Cretaceous dinosaurs known from Africa. The Early Cretaceous was an important time for the dinosaurs of Africa because it was when Africa finally separated from South America, forming the South Atlantic Ocean. This was an important event because now the dinosaurs of Africa started developing endemism because of isolation. The Late Cretaceous of Africa is known mainly from North Africa. During the early part of the Late Cretaceous, North Africa was home to a rich dinosaur fauna. It includes Spinosaurus, Carcharodontosaurus, Rugops, Bahariasaurus, Deltadromeus, Paralititan, Aegyptosaurus, and Ouranosaurus.

Pegomastax 2012 Elliot Formation (Early Jurassic, Sinemurian)  South Africa The morphology of its jaws and beak suggests a diet of tough plants
Plateosauravus 1932 Elliot Formation (Late Triassic, Norian)  South Africa Known from multiple specimens, including those of juveniles
Pulanesaura 2015 Elliot Formation (Early Jurassic, Hettangian to Sinemurian)  South Africa A low browser that lacked the extremely long neck of later sauropods

Rukwatitan 2014 Galula Formation (Late Cretaceous, Campanian to Maastrichtian)  Tanzania One of the few titanosaurs known from central Africa, filling in a gap in their evolutionary history
Sauroniops 2012 Kem Kem Group (Late Cretaceous, Cenomanian)  Morocco Only known from a single, thickened frontal. Suggested to be a synonym of Carcharodontosaurus[13] but this has been refuted[35]
Sefapanosaurus 2015 Elliot Formation (Early Jurassic, Hettangian)  South Africa Had a distinctive cross-shaped astragalus
Shingopana 2017 Galula Formation (Late Cretaceous, Campanian to Maastrichtian)  Tanzania Most closely related to South American titanosaurs
Spicomellus 2021 El Mers Group (Middle Jurassic, Bathonian to Callovian)  Morocco The oldest ankylosaur known and the first one from Africa. Uniquely, its osteoderms were fused directly to its ribs
Spinophorosaurus 2009 Irhazer Shale (Middle Jurassic, Bathonian)  Niger Originally described as possessing a "thagomizer" similar to those of stegosaurs;[36] these turned out to be misidentified clavicles.[37] A high browser with tall shoulders and an elevated neck[38]
Spinosaurus 1915 Bahariya Formation, Chenini Formation, Kem Kem Group (Late Cretaceous, Cenomanian to Turonian)  Algeria
 Egypt
 Morocco
 Tunisia 		Possess a myriad of features that have been suggested to be evidence of a semiaquatic lifestyle, including webbed feet[39] and a paddle-like tail;[40] it is however debated if it was a marine piscivore[41] or a shoreline generalist[42]
Spinostropheus 2004 Tiourarén Formation (Middle Jurassic to Late Jurassic, Bathonian to Oxfordian)  Niger Although often considered a close relative of Elaphrosaurus, these inferences are based on a specimen that cannot actually be referred to this genus[43]
