"2 masterpieces of speculative naturalism" Topic

I just finished reading Steve White's Osprey title "Dinosaur Hunter and I'm part way through William Stout's "The New Dinosaurs". Both of these titles use what can be inferred from the fossil record to"reconstruct what life may have been like during the Mesozoic. I'm on my second edition of Stout's book, which I first stumbled upon in the 1980s and was drawn in by the excellent illustrations that are worth the price alone.

I presume Stout's 2nd ed is significantly different than the first edition. Does he compare old thoughts vs new, or just jump into what is believed to be true now?

Surprised/not surprised Osprey has a dinosaur book. Perhaps fodder for a future Warrior series like SS vs. Raptors or Spartan vs. Triceratops. Any new thoughts here, or more of a compilation of facts and ideas?

Stout's book seems to not significantly change between editions, though 40+ years have passed. The artwork stands the test of time. The book touches on such topics as feathers
and evidence for social behavior that were radical in 1981. Dan White's Osprey title must have required a "deep dive" on the geological formations of the Mesozoic in order to write plausible short stories of safaris in time. It makes Jurassic Park seem like preschool fare.

The latest edition of Stout's book does have an Afterward that brings the book up to date.
