Diplodocus (name meaning "Double Beam") is a genus of diplodocid sauropod dinosaur that originated during the Late Jurassic period in what is now North America. Perhaps the longest sauropod dinosaur ever discovered, measuring 27 meters long and weighing 25 tons, Diplodocus is also acknowledged as being among the most easily identifiable dinosaurs.
One of the primary creatures needed for the park, in the Series 2 episode "Land of Giants", a herd of nine Diplodocus (consisting of six adults and three juveniles) were brought to the park from Late Jurassic Colorado, 152 million years ago. They reside in the Sauropod Savannah Enclosure with many of their other fellow sauropod relatives and recently welcomed hatchlings.
Facts[]
Era & Discovery[]
Diplodocus lived in North America during the Late Jurassic Period from 165 to 145 million years ago. It shared its environment with other creatures like Allosaurus, Ceratosaurus, Ornitholestes, Anurognathus, Brachiosaurus, Apatosaurus, Camarasaurus, Stegosaurus, Dryosaurus, and Nanosaurus.
Physical Attributes[]
Diplodocus stood 5.93 metres tall and weighed 25 tons, making them the longest of all the sauropods.
Diplodocus used their long but stiff necks to graze over large areas with little effort. To balance their necks, these sauropods had long tails with elegant whip-like ends that were used for communication between members of the herd. Diplodocus also had spines on their backs which may have been used to protect themselves from predators like Allosaurus.
Like Scutosaurus a few million years earlier, Diplodocus swallowed stones so they would help grind food in their stomachs. Their teeth were simple pegs that not designed to knip or chew, but were perfect for stripping ferns of their leaves and more suited to soft green leaves rather than woody branches.

Behavior & Traits[]
For protection, Diplodocus moved in herds of 30 or more. Like all sauropods, Diplodocus laid eggs in the ground on the edges of forests.
