Re: Re: Re: Re: Steve Duggan's photo
Again - thanks... but what does that mean..."a specimen of fossil feeding traces/worm castings"? Prehistoric fossilized worm poop? or at least, traces of it? (Seriously!)
(F.Y.I.: I used vinegar for an acid test - no fizz.)
It my rock particularly unusual? rare? scientifically important?
Thanks for your interst!
