The Native American people have provided the author with detailed, accurate descriptions of huge animals, which are thought to be extinct. The author has in turn determined the safest, easiest manner in which these animals can be proven to exist. They include the pterodactyl, Sasquatch, basilosaurus- the walking whale-, woolly mammoth, sober toothed cat, Jefferson ground sloth and many more. Now it is up to members of the public to assist in locating them.
