Trilobite!: Eyewitness to Evolution

A solid and interesting work on trilobite paleontology. Fortey provides us with lots of detail on the animals themselves, their distribution over space and time, the history of those who studied them, and their importance in the overall geologic picture.
Fortey is a very good writer, and he makes what most would probably consider an arcane subject accessible to interested non-specialist.
Solid four stars.
