Lioestheria

Lioestheria is an extinct genus of clam shrimp that thrived from the Carboniferous to the Cretaceous (360.7 to 99.7 Mya).^[1] 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.^[1]
