Yes, Dougal Dixon's books are great. I've seen one other, called Man After Man, which basically assumes that humans, through genetic manipulation and later natural evolution, branch off into a bunch of weird species over the next hundred million years. A thousand or so years in, civilisation collapses, and at the very end the aliens show up, only they're us. It's pretty cool, charting a process of evolution rather than giving a slice of time like his previous books.
I've got New Dinosaurs, and it would make a fascinating world now that I think about it. Brickets browsing from the tall trees (crested dinosaurs with wooly coats and brightly striped tails), titanic gestalt hives on the riverbanks (gestalts are dog-sized hive dinos that survived the Ice Age by building these house-sized constructions), and the ultimate wolf in sheep's clothing, the jinx (it looks exactly like the herbivorous coneater, its chosen prey) - just a sampling of the dinosaurs in Europe. I'm certain that any intelligent species would do something weird and create bizarre new domesticated species...
