Yes, two fossilized pearls from the Niobrara chalk of western Kansas. My son found them and gave them to me. The small one measures 4 mm diameter and the larger 8 mm.

Giant clams lived in the inland sea that divided north America during the age of the dinosaurs. They grew to five feet in diameter.

The small one on the right measures 11 x 9 inches and the piece of a larger one 7 x 15 inches.
