People are ridiculous complaining about random dinosaur inaccuracies. This is a movie for children - a little brutal - but somehow my boys don't care and love it. They've watched this as many times as I used to watch Dumbo. (Wait, you mean elephants can't fly?) If you want a documentary on tarbosaurus or tyrannosaurus or velociraptor, then this isn't for you. I wouldn't watch an action film and then complain about how the drama was unrealistic. My recommendation: don't overthink this people.
