From publisher blurb:
The next installment of the Prehistoric Animals line present five new beasts to add to your OGL game. Each animal in this series existed on our planet in the distant past, and is presented with full stats, an accurate illustration, notes on combat and tactics, useful information for players, and even a bit about the animal in the real world.
The five animals presented in this product take you back to the murky past of the Cambrian Period, up through the dinosaur-ruled Mesozoic, and into the Age of Mammals. Each animal can serve as a potent adversary, or even a faithful animal companion, mount, or familiar.
So add a bit of the primeval to your campaign with Blackdirge Publishing and Animal Archives: Prehistoric Animals.
