RE: Ammonite colouration (was Re: SVP Preview)

Wow!  Two gills only?  That's huge!  A single pair of gills is what
separates squid, octopuses, etc. (coleoids) from nautiloids.  That fact
that someone knows how many gills (not to mention tentacles) ammonites
had is extremely important---how is it that this fact isn't common
knowledge?
