If you’re not really up to date on the modern science around dinosaurs, this is a pretty good way to catch up. It doesn’t go into enormous amounts of detail about any one dinosaur, and it’s honestly rather more surprised about feathered dinosaurs than I would think is warranted at this point, but it makes for a good overview. There is a lot of personal detail here about what made him interested in dinosaurs, various scientists, etc, etc. There’s a lot of name-dropping, and though I didn’t twig at the time, other reviews mentioning that it seems like a total boys-only club are quite correct.
It’s nothing astounding and not really in-depth enough to have wowed me. More of an adult’s version of a pretty basic intro to dinosaurs. That has its place, but not really on my shelves!
