National Geographic Ultimate Dinosaur Encyclopedia

Try to choose some foreign translated books, and some encyclopedias published by dk are also good. Some dinosaur paleontology books published by bbc and National Geographic (in this case, National Geographic of the United States) are quite brilliant from pictures to knowledge. Another suggestion is to buy books with Latin scientific names, because the Chinese names of paleontology were later translated, which led to many names, such as Abbotalon and alberto Dragon, being dinosaurs, so it is easier to use Latin scientific names.
