Aylacostoma stigmaticum

Aylacostoma stigmaticum is a species of freshwater snail, aquatic gastropod mollusc in the family Thiaridae. This species disappeared after the building of the Yacyretá Dam on the Paraná River, in between Argentina and Paraguay.[3] Although listed as extinct in the wild by the IUCN, no captive population survives meaning that it now is entirely extinct.[4]
