This is a impressive, 14" long, Diplodocus caudal (tail) vertebrae collected this past year from one of our partner's private quarries East of Dinosaur, Colorado. It was uniquely prepared, still partially embedded in the hard sandstone in which it was found. Because it was found is such hard rock the bone preservation is excellent. The dark, black coloration is natural. The top of the process has been restored and there is some surface restoration to the back edge of the centrum where some erosion had occurred.
This piece would make for an exceptional display and it's not very often you see dinosaur material presented in this manner, in it's natural state still in the rock.

One of the best-known sauropods, Diplodocus was a very large long-necked quadrupedal animal, with a long, whip-like tail. It could reach up to 115 feet in length but had a relatively small skull, and a mouth full of small peg-like teeth it.
