Animal Archives: Prehistoric Animals III

This 24-page OGL supplement presents eight creatures from the Carboniferous, Permian, Cretaceous, and Pleistocene eras, including giant arthropods, mammal-like reptiles, prehistoric crocodiles, monitor lizards, and other swamp- and Underdark-dwelling threats. Each entry includes game statistics, illustrations, combat tactics, player information, and notes on the creature’s real-world history. 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 the cave creature, metallivore, and toadspawn templates.
