Alright, so it goes like this:
Tribal Warfare
The Hunt
The Journey
That's the order I should be reading them?
Well, since the first issue of The Journey isn't out until November 4, I'd start on the other two. Otherwise I would read Tribal Warfare first, since it's really just a tale of all out war, making the T.rex and Deinonychus relationship in the tale comparable to an escalated version of today's relationship between lions and hyenas in Africa. There really aren't any truly redeemable characters; all are thoroughly brutal protagonists and antagonists who have embraced their predatory roles on a level comparable to warlords and autocrats.
There's a good bit more depth to The Hunt, centered around an Allosaur's coming-of-age/revenge tale opposite a marauding pack of Ceratosaurs with cryptic coloration that would make chameleons envious.
Tribal Warfare
The Hunt
The Journey
That would be my recommendation, though again thus far there are no connections between the insular narratives.
