Diplodocids may have had flexible necks, but take for example
_Mamenchisaurus_ which (relatively) had the longest neck of any
sauropod, and the most cervical vertebrae. Its neck would have been
very rigid - on account of the bony rods projecting from the
cervical ribs of each vertebra which overlapped the succeeding
It used to be thought that _Mamenchi_'s neck was held horizontally
and was used to sweep from side-to-side over lakes and swamps, so the
head could pluck the soft water plants below. (Sort of like a giant
vacuum cleaner.) But, since then _Mamenchi_ has been shown to have
teeth more like _Camarasaurus_ and _Euhelopus_ than diplodocids.
