I'd say "way, way, cool!" is how cool that is... I didn't recognize the authors' names as TONMOers, or was it a TONMOer who just reposted, not authored? Or am I just clueless? or is it the mysterious "Um..." who hides his name from the uninitiated?

Wow.
...Holy crap, that's really awesome! Hermit crabs have been using gastropods since at least somewhere in the Cretaceous, I know that -- I suppose that, as cuttlegirl points out, that's a good thing. I don't think I remember any earlier than that. Don't know how much of a transition it is, though. I think I'll look into that; I'll edit this if I find anything interesting.

That's an interesting point cuttlegirl. I wonder if hermits switched from ammonites to gastropods or whether they used both kind of shells throughout their evolutionary history. I have always thought they were opportunists using whichever shells for shelter that came along, but maybe they are species specific in their choice of shells? I really don't know. I'm sure a decaying ammonite would have made a good meal for such a roving scavenger.
