Sizes of Diplodocus carnegii (orange) and D. hallorum (green) compared with a human (blue) Among the best-known sauropods, Diplodocus were very large, long-necked, quadrupedal animals, with long, whip-like tails. Their forelimbs were slightly shorter than their hind limbs, resulting in a largely horizontal posture.
Diplodocoidea is a superfamily of sauropod dinosaurs, which included some of the longest animals of all time, including slender giants like Supersaurus, Diplodocus, Apatosaurus, and Amphicoelias. Most had very long necks and long, whip-like tails; however, one family (the dicraeosaurids ) are the only known sauropods to have re-evolved a short ...
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.

Humans’ closest primate relatives lost their tails long ago, but exactly how has remained a mystery. A breakthrough in genetic research may finally offer answers.

Dippy is a composite Diplodocus skeleton in Pittsburgh's Carnegie Museum of Natural History, and the holotype of the species Diplodocus carnegii.It is considered the most famous single dinosaur skeleton in the world, due to the numerous plaster casts donated by Andrew Carnegie to several major museums around the world at the beginning of the 20th century.
Diplodocus restored with an upright posture, based on comparison with living animals, from Taylor et al., 2009. Sauropod neck posture is a subject occasionally debated among scientists, with some favoring postures closer to horizontal whilst others a more upright posture. Research has looked at various avenues of evidence and analysis including ...
