Diplodocus
A long neck, a longer story in its tail bones
This familiar sauropod takes its name from small bones beneath the tail, rather than its most obvious features.

Beyond the game
The real Diplodocus
Diplodocus is recognizable by its very long neck and tail. It was a four-legged plant eater and one of the familiar sauropods of the Morrison Formation in western North America. Its proportions differ from the taller-fronted outline of Brachiosaurus.
Its name refers to double-beamed bones beneath the tail. Those less conspicuous structures were described in the nineteenth century. Fossil identification often depends on details like these, alongside the broad features that make a dinosaur recognizable in an illustration.
Comparing Diplodocus with Apatosaurus also shows variation within related sauropods. A long neck does not mean identical vertebrae, limbs or body proportions. Preserved bones provide the starting point for reconstructing each animal and interpreting how its body fitted together.

Get to know Diplodocus
Questions, answered.
What does Diplodocus mean?
The name refers to paired structures in bones underneath the tail. These bones have two branches rather than the simpler shape seen in many other dinosaurs, inspiring a name that means double beam. [1]
What did Diplodocus eat?
It was a herbivore with slender teeth suited to gathering vegetation. Its long neck extended its reach, allowing it to explore a broad feeding area without constantly moving its heavy body. [1]
Where have its fossils been found?
Diplodocus comes from the Late Jurassic Morrison Formation of the western United States. That rock sequence also preserves dinosaurs such as Stegosaurus and Allosaurus, helping reconstruct the wider community around it. [1]
