Trilobite

"With Fortey's expert guidance, we begin to understand how trilobites reveal the pattern and mechanism of evolution through their fossil legacy in the rocks. Through the eyes of trilobites, he allows us glimpses of former worlds as foreign in their geography as in their life forms. Altogether, he provides a unique picture of our geological past, which in turn provides us - scientist and layperson alike - with a new grasp of the wonders of scientific discovery."--BOOK JACKET.
