Liostrea is a genus of extinct oysters, marine bivalve mollusks in the family Gryphaeidae.[1]
These fossils range from the Carnian Epoch of the Triassic Period to the Cenomanian Epoch of the late Cretaceous Period and were widely distributed geographically. They were encrusting organisms, attaching firmly to the substrate on their left shell, and were important Jurassic reef-forming organisms. The species L. erina[2] and L. roemeri[3] attached themselves to living ammonoids.
Liostrea formed abundant ostreoliths (concretions composed of encrusting organisms) on the hardgrounds of the Jurassic Carmel Formation in southwestern Utah.[4]
