Diplodocus: Dinosaur Quick Facts


Diplodocus was a long-necked, whip-tailed giant, measuring about 90 feet long with a 26 foot long neck and a 45 foot long tail, but its head was less than 2 feet long. Its nostrils were at the top of its head probably so it could keep its head just above water and still breath, and it had peg-like teeth, but only in the front of the jaws. Its front legs were shorter than its back legs and all had five-toed feet.

3 Interesting Facts About The Diplodocus

1. Diplodocus had a 26 foot long neck and a 45 foot long, whip-like tail. Its head was less than 2 feet long and its nostrils were at the top of the head. The front legs were shorter than its back legs, and all legs had elephant-like, five-toed feet. One toe on each foot had a thumb claw, probably for protection.

2. It has been determined that Diplodocus could not hold their necks over about 17 feet off the ground.

3. It used to be thought that the sauropods had a second brain. Paleontologists now think that what they thought was a second brain was just an enlargement in the spinal cord in the hip area.
