TAC Creature Database

Every creature. Every era.

The animals from the videos, one record each: size, age, habitat, diet and the facts that matter, checked against the fossil papers, with the creature drawn to scale beside a human. Every one has its own page with the full story, a 4K picture and a free 4K card.
