And you missed the blatant deception in the first paragraph: “Recent research suggested, for example, that many longstanding dinosaur reconstructions were almost double the size of the actual dinosaurs.” If you follow the link, you’ll find that the study referred to body mass, not “size.” Brian wants us to think that dinosaurs weren’t really as big as depicted, when all that’s being suggested is that they might have been skinnier.
skinnier, but denser.
