Just came across an article - haven't read it beyond the abstract and a quick scan, but it's got some interesting info regarding Beringian mollusks. Primarily they suggest mollusks were introduced by migratory birds to the area. Hmmm...
LAURIOL, B., Cabana, Y., Cinq-Mars, J., Geurts, M.A., Grimm, F.W. 2002. Cliff-top eolian deposits and associated molluscan assemblages as indicators of Late Pleistocene and Holocene environments in Beringia. Quaternary International. 87, 59-79.
Reminds me of a previous post by Aydin regarding a book on a similar topic.
What a coincidence! I just read that paper & am going to post about it tomorrow or Saturday.
