Were you wondering why they had long tails? If there are other species still to be discovered? Whether any were poisonous? What colors they were and how we know? How they're connected to birds? And what, sadly, killed them off forever? Take a "spin" and learn the facts about dinos with duckbills and plates, that came early and late, and that left fossils in the sand for us to see. Stuffed with fun information and filled with pictures of dinosaurs on the move (and their skeletons, too), here's the information you've wanted to know. With special mention of record-breaking sauruses, too!
