A concretion containing two very large shark vertebrae. There is potentially more vertebrae in the concretion and I will have to do a prep to see. There is a chance that this could be from a megatoothed shark such as Otodus. This was found next to another, smaller concretion which also contained a shark vertebrae, potentially from the same shark.
Diameter of the shark vertebrae is 11cm.
It weighs around 30kg.
