A Pachyrhinosaurus could be used. And just like operation genesis, an Albertosaurus is a major request. For me, 2 Albertosaurus living together will even things in my strong idea. It must be a few meters taller and longer than the Ceratosaurus like JPOG.
Good thought! Overall it still wouldn't be complete without the Albertosaurus which is pretty tight idea. You know I just thought of another raptor, though it's not a Canadian dinosaur, the Utahraptor!
