The balance between specific discoveries and general evolutionary history allows a clear and current understanding of verte- brate evolution, and showcases the beauty of the extinct animals. Thus stunning pho- tographs, for example of the exquisitely preserved fossils from the Chengjiang Biota, sit alongside remarkable reconstruc- tions of creatures and habitats. Informative drawings show the family trees of major vertebrate groups and biological structures such as tetrapod limbs. I do have quibbles. The chapter on basics such as how fossils form will help begin- ners, but the rest seems to be written for advanced readers.
