The Trialeti culture was known for its particular form of burial. The elite were interred in large, very rich burials under earth and stone mounds, which sometimes contained four-wheeled carts. Also there were many gold objects found in the graves. These gold objects were similar to those found in Iran and Iraq.
In certain theories for locating the Urheimat (homeland) of the Proto-Indo-European language, this culture is identified with the speakers of the Anatolian languages, and even as an earlier Urheimat. Soviet scholars Tamaz Gamkrelidze and Vyacheslav Vsevolodovich Ivanov placed the homeland in Armenia in the 1980's.
