Never seen JP? How can this be? I even read the book, it's much cooler than the movie.
Yes, there are some referencs to JP, which is perfectly normal, the producers have to base the dinos on something don't they? There ae just so many ideas, so they opted for some that have already been used.
One thing I hate is Spinosaurus with long faces like Baryonix, there faceswere flatter, more like a raptor's face.
