Spinosaurus aegyptiacus (spin·o·saur·us/pronounced SPINE-oh-SORE-us) (Greek for "Giant Spined Lizard") is a species of large spinosaurid theropod dinosaur that inhabited early to mid Cretaceous (Cenomanian) Northern Africa, approximately 112 to 93 million years ago.
Fully grown adults could possibly attain lengths of upto 16 meters long, around 6 meters tall at the head an 7 to 9 tons in mass (making it even larger than the Tyrannosaurus and Giganotosaurus in-terms of length and mass), though some weight estimates range as high as 21 tonnes.
