Not the best ammo, and not the worst.

  Here is an ammonite concretion that I ran into the other day in a box.  Most of the shell material was gone so I decided to polish it.  I can remember were I got this, but it may have come from one of 11 boxes I found in a guys basment a very long time ago.  Most of those were lobster concs, but i do remember a couple being ammos.  Not a clue as to Genus or species but positive its Cretaceaus.  Its not the best ammo, but far from the worst!

Beautiful, and the fact that you have the other half to display with it is the topper. What did you polish it with?

Very nice Ron. The polish sure brought out the sutures.

Thanks guys.  

 

Aerogrower:  I used a barrel sander, (120 grit) to get it to where i wanted it, then it was hand sanding under the sink faucet with some wet/dry sand paper, 200 grit then 320 grit, then polished with chrome ruge with a small polishing wheel.  Taaaa Daaaa!!!   It was actually quite easy, took less than 3 hours.

Beautiful!  I suspect it might be some species of Pachydiscus.
