Diplodocus, meaning 'Double-Beam' is a Diplodocid Sauropod dinosaur from the Late Jurassic 155-145 million years ago existing for approximately 10 million years. It had a long whiplash tail for attacking enemies like Allosaurus or Ceratosaurus and probably had a row of spines running along its neck, back and tail.

In The Incredible ThreatEdit

As the team go through an anomaly to save Connor from a pack of Allosaurus, the team encounter many sauropods including Diplodocus along with Apatosaurus, Camarasaurus and Brachiosaurus. A whole herd of them can be seen grazing on fern prairies. After the team save Connor, while the Allosaurus's chase the team, they stumble across a huge Diplodocus and try to avoid its huge whiplash tail.


Diplodocus was a "lizard-hipped" dinosaur. It was a sauropod, a group which were especially abundant in the Late Jurassic period. Diplodocus had simple peg-like teeth for stripping soft foliage like ferns but it could not chew. It swallowed stones which it held in its stomach. These gastroliths, as they are called, helped by grinding down the plant material.

Diplodocus was the longest of the land animals but not the heaviest. Much of its length was taken up with its strong whip-like tail. It had a brain the size of a fist. It had a concentration of nerves in the base of its spine. This helped it to cope with it's enormous size, and control its hind legs and tail.

The largest Diplodocus is usually noted as being 15 tonnes and 27 metres long. A huge animal called Seismosaurus was found in New Mexico and many palaeontologists believe it is really an old Diplodocus. It weighed 30 tonnes and was 45 metres long.
