New Illustration for you Bigfoot Lunch Clubbers. As most primatoligist and anthropologist know, we humans share a classification called Homindae which includes Pongidae (the three/four other great apes; Gorillas, Orangutans, and Chimps/Bonabos).
Well, obviously BF would fit into that class as well. Above are the skeletons of the homidae/pongidae family, notice different porportions such as a a gorillas wider torso, orangutans longer slimmer build, and the chimps thicker, stockier leg bones. The BF skeleton is a blend of a Gigantopithecus reference and the Patterson film.
