When the Notosuchus picks up the egg with its jaws, it actually passes halfway into its face. This becomes obvious when the animal turns its head to the side.
Carcharodontosaurus is not known from any South American fossil sites, only from Africa, yet in this episode, it is shown living in ancient South America. The creators should have chosen Giganotosaurus: a strikingly similar and equally giant dinosaur, which is known to have lived in that area. In fact these two animals look so similar that such an easy solution as switching out their names in the narration could have solved the problem.
