Aegyptosaurus

Aegyptosaurus meaning 'Egypt’s lizard', for the country in which it was discovered (Greek "sauros" meaning 'lizard') is a genus of sauropod dinosaur believed to have lived in what is now Africa, around 95 million years ago, during the Late Cretaceous Period (Cenomanian faunal stage). 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. "Aegyptosaurus" was a close relative of "Argentinosaurus", a much larger dinosaur found in South America.
"Aegyptosaurus" was described by German paleontologist Ernst Stromer in 1932a. Its fossils have been found in the Bahariya Formation of Egypt, Niger (Farak Formation), and in several different locations in the Sahara Desert. All known examples were discovered before 1939. The fossils were stored together in Munich, but were obliterated when an Allied bombing raid destroyed the museum where they were kept in 1944, during World War II. Only fragments from other specimens have survived until today, mostly in the form of indeterminate specimens from Niger.
The holotype (1912VIII61) consists of three caudal (tail) vertebrae, a partial scapula (shoulder blade), and some limb bones; of which was discovered in Egypt in 1932.
In 2010 Gregory S. Paul estimated its length at 15 meters (50 ft), and its weight at 7 tonnes (7.7 short tons).
