Mamenchisaurus Size

Mamenchisaurus is a dinosaur genus including several species known for their remarkably long necks. Perhaps the largest species is M.sinocanadorum at 26 m, additional remains attributed to this species but not yet formally described, the restored skeleton measuring 35 m in length.

Fossils have been found in Asia (China).


(If possibly M.sinocanadorum was 35 m in length then it's neck alone could be 16 m long or more and that would be the longest neck of any dinosaur or any animal for that matter. M.sinocanadorum estimated to have originally measured 26 m in length even though i have given a slightly larger size at 28 m considering the additional remains which may belong to this animal and is not formally described.)
