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.

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.
They state that the feeding ranges for sauropods like Diplodocus were smaller than previously believed and the animals may have had to move their whole bodies around to better access areas where they could browse vegetation. As such, they might have spent more time foraging to meet their minimum energy needs.
The lizards were “commonly found on tree branches, shrublands, crevice‑filled rock piles, or soil walls at forest edges.” These scaly predators feed on insects and spiders.
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.
High up on a mountain in central China, a “large”-eyed creature sat on a plant, hidden in plain sight. The spotted animal had managed to escape notice for years. When scientists finally found ...
The bodies were found scattered, some in the living room and some in the bedroom, suggesting it was not a ritual suicide. There were also no signs of theft, the suitcases were unopened.
Apatosaurinae (the name deriving from the type genus Apatosaurus, meaning "deceptive lizard") is a subfamily of diplodocid sauropods, an extinct group of large, quadrupedal dinosaurs, the other subfamily in Diplodocidae being Diplodocinae. Apatosaurines are distinguished by their more robust, stocky builds and shorter necks proportionally to ...
