Diplodocus

Information
The Diplodocus longus was a large sauropod that lived towards the end of the Jurassic period, 161 to 145 million years BCE. It's 24-meter (79-foot) long body deterred most of its predators, such as Allosaurus and Ceratosaurus. If that was not effective, Diplodocus had a whip-like tail in handy.

Design
The Diplodocus longus was mainly grey in color, with a lighter underbelly and darkened spots on its back. The Diplodocus is nearly featherless, with just a few quills on the back of its head and neck. The elongated tails also have small spikes at the end.
