Marshall Brain’s HowStuffWorks has an small article on the animatronics in Jurassic Park 3.
They mention some interesting stats:

“Rosengrant calls the Spinosaurus a “hot rod” animatronic. Everything on the Spinosaurus has more power than usual. The hydraulics have larger cylinders than normal and provide approximately 1,000 horsepower. The Spinosaurus is such a powerful machine that it can literally tear a car apart. When the tail is whipped from one side to the other, it reaches 2 Gs at the tip.”

Though most of the article should sound familiar to our hard-core fans, if you’re new to Jurassic Park it might be interesting.
