Aegyptosaurus /iːˌdʒɪptoʊˈsɔːrəs/ (meaning 'Egypt's lizard') is a genus of sauropod dinosaur that lived in what is now Africa, around 95 million years ago, during the Late Cretaceous Period (Cenomanian faunal stage).

[2] Aegyptosaurus was described by German paleontologist Ernst Stromer in 1932, seventeen years after the holotype was sent to Munich,[1] and its fossils have been found in the Bahariya Formation of Egypt, the Farak Formation of Niger and in several other different locations in the Sahara Desert.

[4][5][6] de Lapparent (1960) referred a series of caudal vertebrae from the Continental intercalaire of Egypt to Aegyptosaurus baharijensis.

[4] In 2010, based on Paralititan and other related titanosaurs, Gregory S. Paul estimated the length of Aegyptosaurus at 15 metres (49 ft), and its weight at 7 tonnes (7.7 short tons).

It lived at approximately the same time and place as giant predators Tameryraptor (formerly assigned to Carcharodontosaurus),[8] Spinosaurus, and the sauropod Paralititan.
