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
from China. Tehuelchesaurus has been found in the
Asfalto Formation and other sauropods from this formation include
- A new sauropod dinosaur from Chubut province, Argentina. - T. H. Rich, P. Vickers-Rich, O. Gimenez, R. Cuneo, P. Puerta & R. Vacca - 1999.
