Diplodocids probably evolved in North America, where most diplodocid fossils are found. [40] However, diplodocids have been found on most continents, including South America, Europe, and Africa. Diplodocids and their close relatives, dicraeosaurids, must have diverged from each other by the time the earliest known dicraeosaurid, Lingwulong ...
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.
Hundreds of assorted postcranial elements were found in the Monument that have been referred to Diplodocus, but few have been properly described. [6] A nearly complete skull of a juvenile Diplodocus was collected by Douglass in 1921, and it is the first known from a Diplodocus .
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.
Diplodocinae is an extinct subfamily of diplodocid sauropods that existed from the Late Jurassic to Early Cretaceous of North America, Europe, Africa and South America, about 161.2 to 136.4 million years ago. Genera within the subfamily include Tornieria, Supersaurus, Leinkupal, Galeamopus, Diplodocus, Barosaurus, and Ardetosaurus. [1] [2]
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.
A new analysis of ancient grains of crystal embedded in rock from the Australian outback suggests Earth had dry land and fresh water some 4 billion years ago — a time when scientists had thought ...
Ardetosaurus can be more precisely classified within the diplodocid subfamily Diplodocinae, which includes sauropods more similar to Diplodocus than Apatosaurus. Diplodocines exhibit a vast range of body sizes, including some of the longest known dinosaurs such as Supersaurus, at 35–40 metres (115–131 ft).
