Hello Everyone,
I've been lurking for a few days, and am enjoying the new worlds I'm
discovering here. I'm not a collector YET, but...
I'm interested in the chambered nautilus. Can you help me distinguish
between:
(a) Belauensis
(b) Pompilius
(c)"the rare paper nautilus"
(d) the ammonite (an ancestor?)
And what do they pump through the chambers--gasses, water, sediment, all of
the above?
Thanks,
Ellen Moore
