I am not much of a fossil person but I really like the contrast on these when they are polished. I googled it and it seems half the people spell it Cladopora and the other half Cladophora. Not a whole lot of information out there but I believe they are Devonian era so about 350 million years old. Collected in the freezing waters of Lake Huron with Jugglerguy earlier this year.

That is way cool! Worth braving the freezing water if you ask me.

You go a good shine on that. I can’t remember if you’ve slabbed them to make jewelry. I think the slabs look great.

This one was just one of the better ones I have seen tumbled. Maybe not the best pattern but the best overall finish for sure. Chuck |

Well Jugglerguy I dug out my slabs. One thing led to another and now I have to cladopora cabs on dop sticks. Stay tuned.  Chuck |

Fine fossil coral you guys found there Chuck.
Coral of that quality is eye catching and in demand. The ladies sure like it.
It is a shame the Indo corals are hard to get and/or so expensive. Trip to Indo ??

I did a little research, looks like spelling it with an "H" is correct. But like you said, many spell it without it.

Trip to Indo ?? Thanks jamespYour Georgia/Florida corals and Indo coral are much better suited for lapidary. This one and Petoskey are both really soft materials. No idea what the black is on this one but it has a very oily smell when grinding and it is really dirty. I do think this one is very underrated though. The patterns and contrast are very unique. Two cabs just finished. Groove wraps in the near future. Chuck |

Stunning! It makes me want to see if I can find similar on the north shore of Huron. I will be somewhat near there at the end of Oct.

I sent a picture of one of those to Paleo Joe (local fossil guy) and asked if it was cladapora. I forget what he called it, but said that it was some sort of a branching fossil I think, but he couldn’t tell for sure if it was cladapora. It’s commonly called cladapora on the Facebook groups about Great Lakes rocks.

Indo and Florida coral is similar in the way it was formed but the Florida variety just did not silicify with such fine of patterns as the Indo. Unfortunately Indonesia is a long ways away making importing their coral so costly. Fine coral is said to have been discovered in Africa fairly recently but I know little about it. |

Chuck hi there -- I'm new to the forum and just posted a collection of rocks that looks like it may fit in the cladophora category. I found the initial reference in Lake Michigan's Rock Picker Guide (Bruce Mueller). please see this link for that thread. did your rocks look like this in their natural form? I found mine along the western shores of lake michigan. |
