Animal Archives: Prehistoric Animals II

This OGL supplement presents seven prehistoric and fantastical creatures, ranging from Cambrian predators and Mesozoic birds to giant mammals and a two-headed devil bird. Each entry includes game statistics, combat and tactics, player information, illustrations, and real-world notes. The creatures can serve as adversaries, animal companions, mounts, or familiars. The supplement also includes expanded guidance on these roles, summon nature’s ally and summon monster appendices with celestial and fiendish versions, and reprints of the abominable and many-headed templates.
