Atlasaurus - AT-lush-SAWR-us - Atlas - the Titan who held up the heavens, according to Greek mythology + Greek sauros meaning "lizard") It was a moderately large genus of sauropod dinosaur from Middle Jurassic (Bathonian to Callovian stages) beds in North Africa.
Atlasaurus was discovered by Monbaron, Russell & Taquet in 1999. It was named after the site of discovery in the High Atlas of Morocco (where the Titan Atlas was said to hold up the heavens) and for the animal's gigantic size (approximately 15 m (50 ft) long). It is known from a nearly complete skeleton, including a skull, found at Wawmda in the Middle Jurassic (Bathonian-Callovian) Tiougguit Formation, Azilal Province, Tadla-Azilal region, Morocco.
