A fantastically long creature, Memenchisaurus sports a neck that represents half of its total length. Summerlee-Challenger has based our developed genotype on tissue found in the m. Hochuanensis specimins, as opposed to the type species m. Constructus which grows a full 50 feet longer.

With forelegs just slightly shorter than its hind legs, this species holds its back nearly horizontal with necks often held horizontal to or high above the ground. They eat mainly leaves from taller trees.
