True. It looked like an animated clay model in some scenes. Not very convincing.

How much bigger were they supposed to be relative to its legs? I found that they
seemed very large as they were depicted.

Even though I'm a proponent of the spinosaur sail theory, I was also
with the rendition of it. It looked too stiff and too smooth, for one thing. It
reminded me a lot of artists' Dimetrodon sail reconstructions. It seemed too
from what I remember of the spines this animal possessed. One would also expect
brightly patterned coloring on an anatomical display feature such as a large

Yes, just like in most dinosaur movies. Shades of gray and brown. Although I
noticed that some of the other dinosaurs were given a bit more color this time
around. They're improving, albeit slowly. The horns should have been entirely

That would have been a nice touch, especially after the battle with T. rex. I
expected some scrapes and cuts, but the spinosaur emerged without a single
indication that it nearly lost its life. The bite the T.rex gave it on the neck
should have killed it outright, if not decapitated it!!

Where would the crest be located? I remember there was mentioned something
regarding spinosaur crests, a few months ago.

Everything in the design of the spinosaur appeared to be reserved, except for
thing, its SIZE. I would have been much more satisfied had they chosen a design
based on Todd Marshall's spinosaur reconstruction. IMO, that is the best
reconstruction I have seen for this species to date.
