Aegyptosaurus, meaning "Egypt's Lizard", is a genus of sauropod dinosaur that lived in Africa around 95 million years ago during the Upper Cretaceous period. Like most sauropods, it had a long neck and a small skull. The animal's long tail probably acted as a counterweight to its body mass. Its tail also ended in a whip-like structure that it used to defend itself against predatory dinosaurs such as "Carcharodontosaurus" and "Spinosaurus".
