Sometimes, comparative zoologists and acheologists determine that a bone fragment found constitutes an entire different species. Can this really be deduced from a buried bone fragment sometimes millions of years old? Are these guesses or fact? Also, if there are no complete skeletons of certain animals (such as some dinosaurs) how can zoologists really know that some dug-up bone fragment belongs to an entirely different species?
