This might have started the same way Darwinia did, as an affectionate sequel to 's Lost World. Bear took exactly the opposite tack in fitting that world to ours; he rearranges geography a bit to make the survival of dinosaurs just plausible, keeps to the 1940s to make the mentalite of the heroic narration just plausible - but the novel is entirely about getting particular dinosaurs to a particular place, and then maybe getting home again.
Bear fully indulges dinosaur geekery, and there are wonderful descriptions of reconstructed or extrapolated dinosaurs. Charming illustrations, too.
