Spinosaurus (meaning "spine lizard") is a genus of theropod dinosaur which lived in what is now North Africa, from the lower Albian to lower Cenomanian stages of the Cretaceous period, about 112 to 97 million years ago.
Spinosaurus was first known from Egyptian remains discovered in 1912 and described by German paleontologist Ernst Stromer in 1915. The original remains were destroyed in World War II, but additional material has come to light in recent years. It is unclear whether one or two species are represented in the fossils reported in the scientific literature. The best known species is S. aegyptiacus from Egypt, although a potential second species S. maroccanus has been recovered from Morocco.
Spinosaurus may be the largest of all known carnivorous dinosaurs, even larger than Tyrannosaurus and Giganotosaurus. Estimates published in 2005 and 2007 suggest that it was 12.6-18 meters (41-59 feet) in length and 7-20.9 metric tons (7.7-23 short tons) in weight. The skull of Spinosaurus was long and narrow like that of a modern crocodilian. Spinosaurus is thought to have eaten fish; evidence suggests that it lived both on land and in water like a modern crocodilian. The distinctive spines of Spinosaurus, which were long extensions of the vertebrae, grew to at least 1.65 meters (5.4 feet) long and were likely to have had skin connecting them, forming a sail-like structure, although some authors have suggested that the spines were covered in fat and formed a hump. Multiple functions have been put forward for this structure, including thermoregulation and display.
This dinosaur can only be found in the video game. It is the biggest carnivorous dinosaur in the game (though it is only as big as an Iguanodon) and the second strongest behind the Carnotaur.
A Goofy version of a Spinosaurus makes a cameo in "Outta Time".

In the second disc of the Collectors Edition, there are two different concept art images of Spinosaurus by Ricardo Delgado in a bonus feature called Creating the Characters: Dinosaurs - Character Designs "Unused Character Concepts".
