Human use

Shells of terrestrial snails, mainly of the genus Megalobulimus, are found in fluvial shellmound (called sambaqui in Brazil) on the Capelinha archaeological site from paleoamerican culture of early Holocene.[5]

The shell of Megalobulimus sp. (local name: "churito") is used in the traditional ethnomedicine of Northwest Argentina when babies are hyperactive and cannot sleep well, then it is advised to put a shell under a pillow.[6]
