There is fossil evidence that a very large ape called Gigantopithecus lived in China. It was about 400 lbs. and 6 feet tall. It's skull was six inches wide and a foot tall. Dr. Grover S. Krantz made the skull in 1996 at Washington State University. He studied Bigfoot also. He made this skull because he wanted to show how it resembled Bigfoot. He made it out of thick clay.
