As becomes a regular occasion in far too many books and documentaries, North American sites and dinosaurs predominate to a nauseating extent (that is, four out of six chapters come from this restricted part of the world), as if nothing else worth reporting happened in the rest of the world. Worse still, it gives the impression that dinosaur evolution in general was the same across the world, ignoring recent findings in e.g. South America, or anything that happened in Gondwana. I know that the best historical records come from North America, but to keep trotting out the same old tropes, even when given a modern revision, is disappointing.
