Reddit reviews A Field Guide to Mesozoic Birds and Other Winged Dinosaurs

Feathers. Check out this delightful book on Mesozoic Birds for some other cool ideas.

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.
  
• Books: There are a wide variety of paleontology-related books. Depending on what he's read, and what he's interested in, here are a few possibilities:

    • Pterosaurs by Mark Witton
      
    • A Field Guide to Mesozoic Birds and Other Winged Dinosaurs by Matt Martyniuk

disclaimer: haven't read it myself https://www.amazon.com/Field-Guide-Mesozoic-Winged-Dinosaurs/dp/0988596504/ref=sr_1_2?ie=UTF8&qid=1355657512&sr=8-2&keywords=field+guide+mesozoic

Thanks! I forgot to mention I have also All Yesterdays, and it is indeed awesome! I also have this which is really cool.

Thanks for the advice. I have The Superorganism by Wilson and Hölldobler, and it's really good. The others I don't know and I will look for!
