Bryozoan Paleobiology

Dr Paul D. Taylor is currently a Postdoctoral Researcher at the Natural History Museum in London where he spent 39 years as a research scientist. He is widely regarded as one of the world's leading authorities on bryozoans.

"The value of the book lies in having all of the latest research in one place, masterfully summarized and illustrated, and integrated with the classic literature, which is all well referenced. It will be a useful addition to any biologist's library."—Marcus M. Key Jr., The Quarterly Review of Biology
