Erm, actually the two genera in this poll are not monospecific, infact, the series does depict two species of Allosaurus, A. fragilis in the main show, and off course, Big Al is A. jimmadseni
Big Al conquered Basilosaurus...it really is the end...Honestly, don't really care for either, but Lio is less accurate and Big Al is more iconic (plus, he's the state fossil of my home state's neighbor)
