This is a brilliant interactive educational tool: a portable disc with details of 40 dinosaurs and prehistoric reptiles in a handy plastic sleeve. It has a rotating inner disk that details facts about each animal. This information includes name, picture, pronunciation, meaning, fossils found, period, weight, length or wingspan and diet. Further detailed description outlines the most important features about each animal. The facts have all been approved by The Natural History Museum, London. This is something kids will come back to again and again.
