(Riyadh, Saudi Arabia)
This fossil has been found at 150 km Northern of Riyadh, Saudi Arabia.
Unfortunately the main body is really damaged whereas 4 plaques of the shell (?) are in really good conditions.
All around is plenty of fossils of corals, and ammonites.
But this shellfish (?) is really a mysterious for us.
Any suggestion for the identification?
