2 more Halysites 'chain coral' from Silurian in Wisconsin, acid treatment
traveltip1 posted a topic in Fossil Hunting Trips
Here are 2 more Halysites 'chain coral' that I found in the Silurian of Wisconsin. The rocks were soaked in diluted muriatic acid for several hours, to partially dissolve the matrix and reveal the chain corals.

Halysites 'chain coral' from Silurian in Wisconsin, acid treatment
traveltip1 posted a topic in Fossil Hunting Trips
I found this rock containing a Halysites 'chain coral' in the Silurian of Wisconsin. I soaked it in diluted muriatic acid for a few hours to partially dissolve the matrix and reveal the silicified coral fossil. Photos are before and after acid treatment.

I found this pretty little chain coral in southwest Michigan glacial drift a couple of days ago. I'm interested in whether it's possible to narrow the ID down between a Halysites species or another genus, like Quepora. My simplistic understanding is that coenenchymal tubules would indicate a Halysites species, so that's what I've been focusing on, although I know there are many other indicators, like size and shape of corallites. size of ranks, shape of luminae, structure of longitudinal tabulae, etc. This piece is probably too silicified to tell without thin sections, anyway, but I thought I'd throw the pics up, in case there's a coral person here who can help me interpret any diagnostic features they see. (The tape measure I tried to hold up in the last photo is cm) Many thanks!

My current quest is to collect at least 1 fossil from each of the Periods. I do not have a Silurian fossil yet, and am considering buying this one. My question is: Is this a fairly decent specimen? The photos are taken of my computer screen using my phone, but I think they should be clear enough. I have tried to make sure there is NOTHING in the photos about the seller or the website... Dang it- How to I reduce the MB so my photo can be posted? grrrrrr....I've tried things I've done before, and none of them work...
