Found 49 in the extensive shore deposits of barnacles, Balanus amphitrite, with Tilopia bones in about 15 minutes. I don't think any bladder snails ever lived in the Salton Sea. I believe these may be Pleistocene "fossils" from the Lake Coahuila basin from before the formation of the Salton Sea (Hanna 1963). I will be interested to learn more.
