We bought this book for our 3 year old who is fascinated with dinosaurs. I was pleased with the illustrations and the easy to follow layout, but when we got to the T-Rex, Xenotarsosaurus and the Yangchuanosaurus, the pictures became too graphic for my son. For example, the T-Rex is carrying what looks to be a severed limb from another animal in it's mouth. I realize that some dinosaurs are meat eaters, but I was hoping this book was a little less explicit. I think this book could be better for an older child.
