Could the "scary new dinosaur" be Utahraptor?

I wish, but sadly no

It'll be this guy: [img]http://images1.wikia.nocookie.net/__cb20111103211858/jurassicpark/images/5/52/Jurassic_Park_the_Game_Troodons.jpg[/img]

I don't think Utahraptor would be any better than JP's Velociraptor, which is only a little smaller in the movie... Being bigger it's even less likely to invade buildings ;) Troodon: I hope not. Also JP's velociraptor is still better than this guy. I did not much like the parts in the game with this dinosaur. I think Carnotaurus was meant and the hint implicated the scene from the second book: chameleon at night time...

I don't think Utahraptor will appear, it's just too similar to the JP velociraptor. The most probable new entry will be the Troodon.

Indeed-- Utah raptor is too similar to velociraptor for it to appear, However, It might be mentioned? the more likely answer it troodon, Especially following the mention of "you'll want to keep your lights on" and in JPTG troodons only attacked in the dark...

Utahraptor is too big to be the new scary dinosaur, and too small to be a real threat. Troodon is the perfect thing to have. Small, poisonous, and it looks wicked, just wicked

I don't know about both Utahraptor and Troodon but my money is on Therizinosaurus. I mean 90cm claws and its a total badass.
