Invertebrate Skeletal Fossils

Invertebrate bodies include the ostracods similar to Candona, the bi-valved crustacean Lioestheria, the fresh water Pelecypod Unio, Ostracods, and brachiopods. Ostracods are microscopic crustaceans that secrete a calcitic bivalved shell that easily fossilizes after the animal dies.


They live in fresh, brackish, saline and hypersaline waters. Architectural variations and chemical composition of their shells can be related to conditions in the aquatic environments.

They are outstanding research tools in paleogeography, paleoclimatolgy and many other aspects of geological investigations.
