This object is a fossilized nautilus that has been cut and polished to showcase its cross-section. Nautilus is a marine cephalopod that use water jets to move through open water areas. Their feet are attached to their head, which is where the name cephalopod comes from. It was discovered in a rock deposition known as the Dammam Formation that was formed during the Middle Eocene period approximately 40 million years ago. This fossil was collected from Umm Bab, Dukhan, Qatar's western region.
The Arabian Plate began to separate from the African Plate in
this period and moved gradually towards the Eurasian Plate.
The Arabian Gulf and the Zagros Mountains formed as a result
of the Arabian and Eurasian Plates colliding.
Qatar was home to a range of marine species. Fossils of ancient
plants and animals from this time have been discovered,
including sea urchins, sharks, sawfish and dugongs.
