Terry Dactyll Posted October 14, 2009 Share Posted October 14, 2009 (edited) FrigginsDiggins.... It depends on its size really.... and your patience... different grades of wet & dry if its not to fiddly, maybe starting at 400 Grit and going to 1200 grit... I go in 200 grit increments, although they suggest smaller jumps to make you buy more paper......followed by a waxing... if you want anymore specific information your welcome to IM me .......Id look for someone nearby whose into lapidry.... you will get a good gloss but retain all the detail, off a buffing wheel.... and Id see if you have a local fossil and mineral collecting club... sometimes they chip together to buy expensive equipment that you can use if your a member.... coupled with the experience there as well, you couldnt fail....I wouldnt rush into it doing it yourself before youve checked....

Bear Posted October 14, 2009 Share Posted October 14, 2009 Nice pic indeed, Figgins. Sure looks like formanifera to me, but I would welcome any more knowledgeable insights on that as I have a Devonian piece that looks almost identical to yours. I see another tutorial coming Terry....'How to polish fossil stuff'. I may even throw in a post or 2 on that topic myself as I am working on polishing a clam fragment fossil for a client ATM.

Auspex Posted October 14, 2009 Share Posted October 14, 2009 Thanks for the great info, Bear. Here's a little better picture of that bottom right specimen. I googled formanifera this evening. Interesting creatures. Isn't this a Chain Coral (Halysites)?

Harry Pristis Posted October 14, 2009 Share Posted October 14, 2009 I think there has been reference to "formanifera" in this thread. Isn't the word you want "foraminifera" - "foram" for short! http://pristis.wix.com/the-demijohn-page What seest thou else In the dark backward and abysm of time? ---Shakespeare, The Tempest Link to comment Share on other sites More sharing options...

Crinoid Queen Posted October 14, 2009 Share Posted October 14, 2009 Isn't this a Chain Coral (Halysites)? All of your guyses corals are fantastic! Smilodon i love those agatized corals those are sweeeet! Rozzilla that branching coral is really nice i believe the bottom picture is a pipe organ coral Iskandar all i can say is WOW! figginsdiggins Yes it is most definatly chain link coral. I have a Pritty nice specimin of this coral too, that I found in MI. I also have another piece of horm coral that is about 3.5 in tall. It came from the same creeks as the Crinoids. I also have a very rare(even though it doenst look like much) species of horn coral, Dibonophylum bipartium, from MI that the individuals at the Chicago Field Museum said is one of the largets pieces that they have ever seen. They wanted me to donate it but it is one of the first fossils I found when I was 14 so Im kinda attached to it Link to comment Share on other sites More sharing options...
Bear Posted October 14, 2009 Share Posted October 14, 2009 (edited) Ah, so we are for sure that it is a chain coral and not a foraminifera colony? *crosses his fingers* Sorry about the spelling....one of my many failings is frequent misspellings, usually of important words. I likely won't get much better though.....will try. Here is mine. and a side view. I found this one in Hungry Hollow, Ontario. I gotta admit it was pretty strange having the whole look of the place change as I was posting this up......looks good though.

And Frank, that big one over a foot across is very impressive. Wish I had one like that. I do have some coral but nothing I have personaly gone out and hunted for, sad to say.

crinus Posted June 2, 2010 Share Posted June 2, 2010 I am always on the hunt for common fossils that will prep out nicely. I found this one at the Paulding, Ohio (Devonian, Silica Shale) quarry earlier this year. It is the coral Heliophullum halli. A VERY common fossil but rarely is it complete from tip to cup. This one is complete. Unfortunately, in my excitement to cleaning it, I started cleaning without taking a "before" picture and only remember about half way through the prep process. Here are the photos. Link to comment Share on other sites More sharing options...

Indy Posted January 3, 2012 Share Posted January 3, 2012 This is a beautiful Pennsylvanian coral collected by a friend near Moscow, Russia Aulopora macrostoma (Fischer) Gzhelian Stage, Rusavkian substage Gzhel quarry, Gzhel village The yellowish and orange color is from small amounts of iron oxides staining the rock and fossil. Look closely at the orange masses in the coral skeleton; they are small concretionary growths of silica that have replaced the calcite skeleton, in the growth form known as beekite rings.
