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] First identified in 1912,[2] they have been found in Germany,[3] Hungary, Colorado,[4][5] New Mexico, Montana, Texas,[6] Utah[5] and China.
