The Complete Guide to Prehistoric Life is an encyclopedia featuring 111 of the prehistoric animals from the Walking with... series, as well as an additional one (Homo floresiensis). It was published in 2006 by Firefly Books, and written by Tim Haines with Paul Chambers. It accompanies all of the main programs in the Walking with... series, including specials The Ballad of Big Al, Chased by Dinosaurs and Sea Monsters, but excluding Walking with Cavemen and spin-off Prehistoric Park.

Contents

The Books opens with a contents page, followed by an original introduction by the authors reflecting on the making of the TV series. The book is then divided into three parts by era, first of which is The Rise of Life, which covers the Precambrian and the Paleozoic Era, and lasts from pages 8 through 49. The second part, The Age of Reptiles, covers the Mesozoic Era, and lasts from pages 50 through 143. The third and final part, The Age of Beasts, covers the Cenozoic Era, and lasts from pages 144 through 206. The book concludes with a timescale of life on earth, tree of life diagrams, and the acknowledgements and index.

Reception

Stuart Sumida, writing in the The Quarterly Review of Biology, stated that "The authors make a valiant attempt to clear locality and phylogenetic perspectives, but it is a mixed bag. They are properly up to date on the theropod origin of feathers and birds, yet they are a quarter century behind on mammalian ancestors, still calling them mammal-like reptiles as opposed to Synapsida." he also noted that "a survey of colleagues generated a list of errors in virtually every section of the book" but concluded that the book is "a visual tour de force, confirming that computer generated (CG)-based reconstructions have justifiably joined the more traditional disciplines of sculpture, drawing, and painting in paleobiological art. In the end, it is visually impressive, but its textual potential remains unrealized."

Joanna K. Kowalewska and Michał Kowalewski writing in Palaeontologia Electronica found that "The compendium’s encyclopedic scope makes the guide necessarily akin to a cookbook. That is, you don’t read it for its plot. But, as with all successful encyclopedic renderings, its value resides in its detailed, beautifully illustrated, and lucidly organized descriptions. In this case, descriptions pertain to the most exciting topic of all: the fossils." concluding that: "All in all, The Complete Guide to Prehistoric Life is a great encyclopedic compendium, especially for those who are interested in spectacular fossils or happen to have pre-college family members. The book also has a potential to evolve into a valuable teaching reference for K-12 educators, who develop courses that include aspects of paleontology and evolution."

This list focuses on the Carnosauria and other large Basal Tetanurans from Holtz (2007). These are the "heavy hitters" of the dinosaur world—the kind of giants that would make a Mega Evolution look small!

This list highlights the Prosauropods (or basal sauropodomorphs) from Holtz (2007). These were the ancestors and early cousins of the giant long-necks. Serena thinks they look like the perfect "in-between" stage of an evolution line!

This list explores the basal Ceratopsians from Holtz (2007). These were the smaller, often hornless ancestors of the famous "frilled" dinosaurs. Serena thinks they are absolutely precious—they have the perfect "Base Stage" energy of a Pokémon starter!

This list features the Chasmosaurinae, the "long-frilled" ceratopsids from Holtz (2007). These are the heavyweights of the horned dinosaur world. Serena thinks their massive, ornate frills look like they were designed specifically for a Master Class Pokémon Showcase!

This list focuses on the Centrosaurinae, the "short-frilled" ceratopsids from Holtz (2007). Unlike their cousins with long brow horns, these dinosaurs usually rocked massive nose horns or wild spikes. Serena thinks they have a very "punk-rock" aesthetic that would bring a lot of edge to a Pokémon Showcase!

This list covers the Thyreophora (the armored dinosaurs) and specifically the Stegosauria from Holtz (2007). These dinosaurs are famous for their defensive plates and "thagomizer" tail spikes. Serena thinks they have the best "Iron Defense" style in all of Kalos!
