As with the related genus Barosaurus, the very long neck of Diplodocus is the source of much controversy among scientists. A 1992 Columbia University study of diplodocid neck structure indicated that the longest necks would have required a 1.6-ton heart – a tenth of the animal's body weight.
Diplodocus, depicted with spines limited to the mid-line of the back. Diplodocids were generally large animals, even by sauropod standards. Thanks to their long necks and tails, diplodocids were among the longest sauropods, with some species such as Supersaurus vivianae and Diplodocus hallorum estimated to have reached lengths of 30 meters (100 ft) or more.

Dog with partially docked tail. Docking or bobbing is the removal of portions of an animal's tail.It should not be confused with cropping, [1] the amputation of ears. Tail docking may be performed cutting the tail with surgical scissors (or a scalpel) or constricting the blood supply to the tail with a rubber ligature for a few days until the tail falls off. [2]
The word "Flagellicaudata" refers to long, whip-like tails of that animals (flagellum is a Latin word meaning "whip" and cauda means in Latin "tail"). [ 6 ] The phylogenetics of Diplodocoidea were reviewed in 2015 by Emanuel Tschopp, Octavio Mateus and Roger Benson with a specimen-level phylogenetic analysis, as well as a species-level analysis.
