Recommendations for non fiction Dinosaur book?

[Littlemissnegative]

DS is in year one and has started a topic on dinosaurs. He has been interested in them for several years now but I have never been able to find a good book for him. Can anyone recommend a few please?

I bought this one for my DS when he was 5 (almost 6), 18 months later it is still one of his favourite books - in fact it has almost dropped to bits now. My review is the top one on Amazon, and says a bit more about it. It really is good - his teacher used it when they were doing a dinosaur project.
