Lioestheria

Lioestheria ('clam shrimp') are an extinct genus of crustaceans that thrived from the Carboniferous to the Cretaceous (360.7 to 99.7 Mya). They fed on detritus, being very small slow moving, nektonic organisms that filter fed as they floated. They have been found in both marine and freshwater environments.
