Turritella

Tower shells (living)

Turritella are the living tower shells, slender and many-whorled with spiral ribs, filter-feeders that live half-buried in sand. Modern shells are cheap; the genus is more familiar to collectors from its fossils, including the Green River 'turritella agate' (actually Elimia) and Cretaceous and Eocene beds. See the fossil taxon article for those.
