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.... ;)

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'. :D 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. ;)

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)?

Go for it Bear.... I know for a fact I can learn a lot from you about polishing rock....... tag it on the prep thread if you so wish, your very welcome.... I cant wait to read it... ;)

I think there has been reference to "formanifera" in this thread. Isn't the word you want "foraminifera" - "foram" for short!

See I thought "Foraminifera" refered to someone with a really scary 'inny' belly button... :P

Be true to the reality you create.

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

:D

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. :)

Wow!! Im not much for coral, but some of you folks have some really nice specimens!!! 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. Here are some pics of some coral pieces where I broke down and bought them.

All of you have some really nice specimens.

Great fossils you all. Here's another Halysites sp. from the Silurian in Indiana and Astrocaenia hyatti Wells from the Jurassic in Montana. Regards, Chris

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.

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.
