Diplodocus is one of the longest dinosaurs ever discovered. It was found in 1877. Its unique body makes it different from others. The name Diplodocus means 'double beam'; this refers to the unique body construction found on the tail of Diplodocus. It possibly served as a counterweight for its neck or provided extra support and greater mobility. In addition to that, it also had sturdy legs. Diplodocus was part of a group of dinosaurs known as Sauropods (Diplodocid). Their size helped them to ward off predators. 

An adult Diplodocus could reach a length of more than 175 feet from its snout to the tip of its tail. This huge dinosaur is estimated to weigh between 11 and 17.6 tons; its enormous tail is said to place its center of mass well back on its body. Its neck and tail occupied most of Diplodocus' length; its long whip-like tail reached 45 feet in length and contained about 80 vertebrae. It had an extremely long neck that could reach up to 21 feet in length, making it one of the longest dinosaurs known on our planet.

Diplodocus was a herbivore, with peg-like teeth perfect for tearing the leaves off ferns and trees, shrubs, cycads and ginkgos. The strange thing is that Diplodocus spent considerable time fermenting its food in its expanded gut and probably did not use stones to aid digestion.

It lived in an area that is now western North America between 146.8 and 156.3 million years ago in the Late Jurassic period. It was about the same time as the dinosaurs Stegosaurus and Allosaurus.

What color was Diplodocus?

The color of the Diplodocus base genome is a reddish brown.

What kinds of things did Diplodocus eat?

Diplodocus was a herbivore; it ate an enormous amount of plant material every day to sustain itself, such as trees, shrubs, cycads, ginkgos and ferns.

How big was a diplodocus egg?

Diplodocus eggs were surprisingly small for such large animals, about the size of a large grapefruit.

What was Diplodocus like?

Diplodocus was known to be the longest dinosaur discovered and had a unique body construction found in its tail. It had stout legs and a huge, long whip-like tail. It had an extremely long neck, and the forelimbs were slightly shorter than the hind limbs.

What was the habitat of the diplodocus?

The long-necked herbivore Diplodocus lived in forest areas that had a wide range of food supplies.

How many Diplodocus have been found?

Scientists found at least four species of Diplodocus; in 1877, the first fossil was found in Canon City in Colorado, and subsequent fossils were found mostly in Montana, Wyoming, Utah and Colorado.

Did Diplodocus lay eggs?

Yes, of course. These dinosaurs laid eggs although there is no evidence of nesting habits.

How did Diplodocus defend itself?

The huge Diplodocus dinosaur had used its long tail to defend itself against enemies.

Why are Diplodocus necks long?

Diplodocus may have used its long necks to feed on high and low vegetation, and to drink water as giraffes do.
