A very nice natural section of plesiosaur vertebrae with some parts of the ribs still intact. This has been stabilised with a coating 5% B72 to help prevent the very flakey sediment from Crumbling but you may still get some dust from underneath this piece. A good sized section of plesiosaur bone from Morocco. Size is 16x14cm across and long. 
All fossils are genuine so will have damages/repairs.
