Spinosaurus aegyptiacus was a highly unusual theropod dinosaur that lived in Egypt and Morocco around 90 million years ago. It is distinctly different from other carnosaurs in the respect that it has an unusually high vertibrae on it's back that give it a giant fin or sail, about 6 feet high, the purpose of which is not understood. It may have served as a cooling device, for heat dissipation or a sexual signal. Interestingly enough, an iguanodont from the same place at almost the same time, Ouranosaurus, had a similar sail.
The jaws of Spinosaurus are narrow and crocodile-like, and the teeth are straight and not serrated like those of Tyrannosaurus. This feature is very similar to the theropods Baryonyx and Suchomimus, both of which were probable fish-eaters.
Spinosaurus is known only from fragments, the first specimen was unfortunately destroyed during World War II. It is estimated that the beast was collosal, perhaps measuring 50 feet in length, but these are only estimates. It seems that although the creature may have been longer than Tyrannosaurus, it had a more slender build.
Pound for pound, both relatively and absolutely, Tyrannosaurus rex is the more formidable animal, despite what the movie Jurassic Park 3 depcits. T.rex would be heavier, more powerfully musculed, and have a much stronger bite than Spinosaurus.
If Tyrannosaurus and Spinosaurus ever fought in real life, T.rex would win, hands down!

The common rational reaction to self-awareness.
Are you depressed for a very good reason, depressed for no good reason, or just depressed?
A spiritually insane, emotinally retarded, and megalomaniacal primate with an immense inferiority complex. It is ill-suited to survive in its environment, so instead of adapting as other species it changes the environment, for ill of everything including itself. It is a species that will surely go extinct in the next thousand years, a victim of its vaulting own success.
Don't blame us, we're only human.
