The spines could be up to 18 centimeters (7.1 in) long, on the "whiplash" portion of their tails, and possibly along the back and neck as well, similarly to hadrosaurids. [ 28 ] [ 29 ] The spines have been incorporated into many recent reconstructions of Diplodocus , notably Walking with Dinosaurs . [ 30 ]
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.

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 ...

The caudofemoralis muscles got reduced during theropod evolution, and are mostly lost in modern birds. Birds, in contrast to long-tailed dinosaurs, do not rely on femoral retraction for propulsion, but instead retracted the lower leg around the knee joint.

The genus is a member of the Diplodocinae, a subfamily of large long-necked dinosaurs with whiplike tails. Ardetosaurus represents one of many distinct sauropod taxa that coexisted in this formation. The Ardetosaurus holotype was collected in 1993 before being shipped to Switzerland, from which it was later sent to Germany, where it was damaged ...
Number 1: The term 'hair of the dog' comes from the tail. Back in the day, Pliny the Elder said that the way to get rid of rabies was to put ashes on the wound.
When a dog wags their tail to the left, it activates the right hemisphere of their brain, which is associated more with negative emotions and withdrawal or avoidance behaviors.”
