If you’re looking for information on the gorgonopsids and their world, this book is rather thin on that. Instead, it’s mostly about Ward’s career and some of his excavations and initiatives. Admittedly, much of that is in the service of getting information about the gorgonopsids, but the book is rather thin on what was actually found. There is some interesting stuff on pinning down that mass extinction and figuring out how fast it happened, but the gorgonopsids in life — how they lived, what they did — are absent.
So pretty interesting in terms of understanding Ward’s career as a palaeontologist, with the appropriate set pieces about how hot it was and how difficult, etc, etc, but low on actual pre-dinosaurian monsters ruling the Earth.
