Ostrea

Ostrea is a genus of edible oysters, marine bivalve mollusks in the family Ostreidae, the oysters.

Fossil records

Although molecular studies suggest that Ostrea first appeared around the Eocene and originated no earlier than the Cretaceous, paleontologists have historically applied the genus to almost all fossil oysters from the Permian onward, many of which are only superficially similar to extant Ostrea. As a result, the genus Ostrea includes about 150 extinct species.

History

At least one species within this genus, Ostrea lurida, has been recovered in archaeological excavations along the Central California coast of the Pacific Ocean, demonstrating it was a marine taxon exploited by the Native American Chumash people as a food source.
