Fossil Oyster Shells - Fossil Bivalve Molluscs - Fossil Molluscs - Fossil Oysters - Fossil Shells
Beautifully double-sided formed shell of these fossil oyster shells from the mountains of Peru. Distinct ridges. Natural finish. The zigzag pattern created by two conflicting need: to keep the shell tightly closed against predators, and the need to open the shell to allow water to be circulated and filtered during feeding. These specimens are from Casamarea, Peru. Unknown specie. Age: Jurasic. 150,000,000 years.

Oysters are bivalve molluscs. All oysters are filter feeders, drawing water in over their gills through the beating of cilia; Plankton and particles are trapped in the mucus of a gill, and from there are transported to the mount where they are eaten. The squestion is usually "how is it that these marine animals are found in the mountains?" The obvious answer is that at one time the area where the fossils are being found was once covered by oceans.
