"During an expedition to the hardly accessible mountainrange of
Baian-Kara-Ula which lies on the borderland between Tibet and
China, the chinese archeologist Chi Pu Tei discovered several cave
burial sites which contained strange, only about 4 feet 4 inches tall
skeletons, whose heads were oversized in relation to their otherwise
slender frame. In each of the total of 716 graves he found a stonedisk
with a diameter of about 1 foot and a thickness of a third of an inch."
