When the female T. rex kills the Anatotitan, there are no wounds visible on its body, only a mere red spot appears on its side. As the predator bites into the Anatotitan, her head clearly passes into the animal several times. The scene is shot from afar, but this doesn't hide the obvious animation goof. See more
There are still islands of greenery between the barren lava flows. In the warm moist climate of the late Cretaceous period, the vegetation has transformed.
