Reddit mentions of Dinosaurs: How They Lived and Evolved

Depending on his interests, here are a few options:

• Model dinosaurs: There are several companies that sell accurate scale models of dinosaurs and other prehistoric life; Safari LTD and Collecta are two of my favorites. Beasts of the Mesozoic are some slightly higher-end poseable raptor models.
  
• If you think he'd be interested in a print of professionally-made dinosaur art, a couple of paleoartists whose sites I could find are Emily Willoughby and Mark Witton.
  
• If he might be into stickers, shirts, or other assorted dinosaur-themed merchandise such as mugs or phone cases: Permia sells shirts, stickers, and cards. Some paleoartists have Redbubble pages or similar. A few I recommend looking at: [1] [2] [3] [4] [5] [6] [7]
  
• If you think he'd be interested in scientifically accurate plushies, Palaeoplushies might be worth looking at.

Here’s one: Dinosaurs: How They Lived and Evolved https://www.amazon.com/dp/1588345823/ref=cm_sw_r_cp_api_i_3kSZDbEF9ENGD

Dinosaurs: How They Lived and Evolved. Don't let the cover fool you, it's a good book.

How old is the kid you're getting the book for? Dinosaurs: How They Lived and Evolved is very new and up-to-date, but is probably not ideal for very young kids. Maybe like 11ish up?

That was a great book that I also highly recommend. Some other suggestions:
