DK has certainly made a name for itself in producing a long line of visually stunning, reference books. Prehistoric Life is a good example of a genre that DK seemed to have invented. The visuals are perfect. DK has some secret printing method that allows its pictures to be excitedly fine textured and vivid. The writing which could be quite pedestrian is well done and done at a adult level. The material is very current and original. It presented material that was totally new to me: the prototaxites on pages 114-115 which look like an eerie spike that was over 26 feet tall and could be either a plant or a fungus. I also liked that DK didn't dwell on dinosaurs (although it has a lot of material about them) but also spent time on plants and invertebrates. At 512 pages it covers a lot of territory. And at the bargain basement price it carries, if you are going to get one book about ancient life, get this book. My only quibble is that the maps showing the distribution of the continents are needlessly simplified. However, that said, I am going to give this my highest recommendation.
