Some Ice Age Land Snails
Okay, if anyone is looking at this blog, it's likely they've glazed over once they saw my long qualifier answers. That's to be expected, so to make up here's a post with few words and lots of images. Below each is my tentative ID. If anyone has corrections, please let me know.
It's probably G. indentata, but I am not familiar with northern species in that genus. H. parallelus is probably correct. Vertigo modesta looks like the drawings in Pilsbry.
ReplyDeleteAs for the succineid, I would call it succineid sp., because one can't reliably determine their genera, let alone species, from shells only. Could it also be a Pseudosuccinea, a freshwater genus?
