[Georgemckenzie]

Hiya everyone I’m interested in this bone block the seller says it’s a mosasaur bone block any help on if the id is right would be great and if the matrix is original many thanks

I think it's croc cervical vertebras

I agree.  I see croc cervical ribs in there as well; along the left side of the block inmost of the photos.

I'm willing to believe whatever you guys are saying, as I can't make heads nor tails of the bones in this piece. In any case, it doesn't look like any recognizable mosasaur material I've seen, if that's any help

Here I have some photos of the late cretaceous Moroccan croc for comparison.

Thanks! That does make things a bit clearer! And I agree, the two blocks do look comparable
