The Answer

This giraffe blip today is very appropriate - I had to pull it over a picture of our grey skies.

Isbi was right. It is a mammal vertebrae and more specifically the atlas of a giraffe. I coloured it green to put a certain person off knowing immediately what it was.

We found all the giraffe bones lying in Botswana and we stopped to pick up a few interesting pieces.
I enjoyed Gatekeepers mystery from the 23rd of March and decided to do the same!
