User blog comment:Boom24/Spino vs T rex/@comment-4948558-20120804024611

Look, everyone! The reason T.rex wasn't the star of the third movie is because he's old news. I too think that T.rex is every bit as awesome as Spinosaurus, but that doesn't change the fact that he's been featured in every single dinosaur film since the dawn of time. Jurassic Park III wanted something new. They decided to go with Spinosaurus because he's bigger, more unusual, and looks pretty badass. If T.rex is still the star for future movies, people are probably going to get bored of the JP franchise, and I know none of us want that to happen.
