The New Dinosaurs: An Alternative Evolution (1988) is a book written by geologist and paleontologist Dougal Dixon. While Dixon's earlier book After Man is set fifty million years in the future, The New Dinosaurs speculates on how the dinosaurs would have evolved over the last 65 million years had the Cretaceous-Palaeogene extinction event not taken place. A detailed critic on the Speculative Evolution Forum can be found here. An more advanced version of this same concept (called The Speculative Dinosaur Project) is represented by a group of paleoartists in recent years.
