       As a macronarian sauropod,‭ ‬Tehuelchesaurus is thought to have had a body form better for reaching up to high growing vegetation rather than sweeping across a broad area to browse upon low growing vegetation like a diplodocid.‭ ‬Although only known from South America,‭ ‬Tehuelchesaurus is actually thought to be very similar in form to Omeisaurus from China.‭ ‬Tehuelchesaurus has been found in the Canadon Asfalto Formation and other sauropods from this formation include Patagosaurus and Volkheimeria.
