I found this super fun and educational website based on PBS's show Dinosaur Train. The print offs are wonderful. They have everything from coloring pages and matching games to a whole chart on dino names from A-Z and how to pronounce them, which is great because some of them are amazingly hard to say!
There is also a field guide section you can check out that not only has images but you can x-ray the dinos, compare size, find out what they eat, and learn some interesting facts. So why not check it out, have some fun, and maybe learn a thing or two!!!
