Very nice complete distal vertebra of the famous Diplodocus. This vertebra is throughly special as the process (neural spine, neural arch) is 100% complete with exception of a little crack fill. It is a very rare thing to find such a vert in this condition.

Diplodocus longus

Jurassic (148 - 155 mil)

Morisson Formation, Wyoming, USA

170 mm - 6.7"

Very good
