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. [3]
Due to the vast amount of scale diversity seen within such a small area, as well as the scales being smaller in comparison to other diplodocid scale fossils, and the presence of small and potentially “juvenile” material at the Mother’s Day Quarry, it is hypothesized that the skin originated from a small or even “juvenile” Diplodocus.
An alternative method, using limb length and body mass, found Brontosaurus and Apatosaurus grew 520 kg (1,150 lb) per year, and reached their full mass before it was about 70 years old. [93] These estimates have been called unreliable because the calculation methods are not sound; old growth lines would have been obliterated by bone remodeling ...
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.
Diplodocid and brachiosaurid members of the group composed the greater portion of neosauropods during the Jurassic, but they began to be replaced by titanosaurs in most regions through the Cretaceous period. [3] By the late Cretaceous, titanosaurs were the dominant group of neosauropods, especially on the southern continents.
The latest dinosaur being mounted at the Natural History Museum in Los Angeles is not only a member of a new species — it's also the only one found on the planet whose bones are green, according ...
Supersaurus (meaning "super lizard") is a genus of diplodocid sauropod dinosaur that lived in North America during the Late Jurassic period. The type species, S. vivianae, was first discovered by Vivian Jones of Delta, Colorado, in the middle Morrison Formation of Colorado in 1972.
Exhumations of bodies four years after death are rare, so it is not easy to compare to larger samples. If someone asked me if it was possible to have a body in this condition after four years, I ...
