mel, that last picture looks exactly like some of the stuff we get here in Michigan the round ones are croinids (bad spelling) the longer fuzzy ones I will get the name for you I don't have it readily avalible but that rock is pretty prevalent here in northern Michigan Dick B.

Mel, are you sure that last one of yours is fossil coral? It looks more like a soft bodied animal, maybe an echinoderm (starfish, sea cucumber, etc). The little round doughnut like bits look like what I have seen offered as crinoid (sea tulip, feather duster) fossil stems. Still very cool, but a diffrent group of animals from coral. If so, this would be from deeper water than the corals would grow as well.

Hi everybody! Here are two pics of a fossil coral colony I found in Lake Michigan, the Leelanau peninsula. Thanks for looking, Wannarock

From what I've heard and seen those small pieces of fossilized coral can be tumbled and polished. Just keep a very close eye on it and tumble it alone. I have a bag of the stuff, along with other fossilized coral that I pick up each year in "Grab Bags" that my local Rock club sell during their annual Show. I plan on giving it a go when I have a good sized load to tumble first in my soft rubber Thumler 3# tumbler. I figure they will last a little longer in that kind of barrel. Then separate the better looking pieces and tumble them in their final stages in my little red 8oz barrels in smaller loads. They seem to get gentler treatment in them for the final polish. Will post pictures when I give it my best shot.
