fernwood Posted March 14, 2018 Share Posted March 14, 2018 Location: SE Portage County, Central Wisconsin, USA. Geology: South Western advance of Green Bay Glacial Lobe. Former Glacial Lake Oshkosh. Niagara Escarpment Debris. My land. Ordovician onward. Reminds me of Ordovician Halysites Coral-Chain Coral, but with a lot of wear. In some places, the chain is partially visible. When a light is held to the cavity edges shown on the first two photos, the walls are very translucent. Medium amber color. I saw the more solid edge and picked it up. Was very pleased when I turned it over, even though it was full of dirt. Like most of the fossils, I find, this one has received a lot of trauma. Possibly a victim of glacier which went through the Niagara Escarpment about 25,000 years ago. Most of my finds have partial or full crystal replacement for the coral stems. Size: 11 cm long by 10 cm wide by 9 cm thick at maximum points. All comments appreciated. Thank you. lace coral 1a lace coral 1c lace coral 2 lace coral 2 ud 2d Link to comment Share on other sites More sharing options...
mikeymig Posted March 14, 2018 Share Posted March 14, 2018 Geologic and cool but not a fossil coral. Many times I've wondered how much there is to know. led zeppelin Link to comment Share on other sites More sharing options...
fernwood Posted March 14, 2018 Author Share Posted March 14, 2018 Then what is it? Local geologist said fossil coral. Very confused now. Link to comment Share on other sites More sharing options...
mikeymig Posted March 15, 2018 Share Posted March 15, 2018 Geologist are not Paleontologist. There are no coral structures (corallite, tabulae, growth lines, septum) just an outward appearance. I see what looks like the imprint of a brachiopod in one of the voids/pockets. What was preserved in those "holes" has weathered away long ago. 1 Many times I've wondered how much there is to know. led zeppelin Link to comment Share on other sites More sharing options...
fernwood Posted March 15, 2018 Author Share Posted March 15, 2018 Good point. Thanks for pointing out the possible brachiopod. Think I found it. The more I learn, the better. Thank you. Link to comment Share on other sites More sharing options...
Tidgy's Dad Posted March 16, 2018 Share Posted March 16, 2018 It may even be similar to the other piece you posted with pentamerid steinkerns still in place, but here they have all been eroded or fallen out. 1 Life's Good!

abyssunder Posted March 28, 2018 Share Posted March 28, 2018 Most of the corallites are too large for Pleurodictyum, but it was said before.

Kane Posted March 28, 2018 Share Posted March 28, 2018 Joining the chorus. Certainly not Pleurodictyum. When considering if the specimen is a fossil coral, one major criteria would be some relative uniformity in the size of the corallites. ...How to Philosophize with a Hammer Link to comment Share on other sites More sharing options...

Pffffffffffff !!!!!!!!!, little uniformity in size of calices presents this specimen. Pleurodictyum americanum Roemer from the Kashong Shale (Hamilton Group), Middle Devonian (Givetian) of Livingston County, New York. Specimen collected by Brian Bade.

Well, I did qualify with "relative" It was a good guess, by the way. I apologize if my comment appeared brusque - not my intention! ...How to Philosophize with a Hammer Link to comment Share on other sites More sharing options...

In the same way, I hope not to seem brusque. It is not my intention either. Link to comment Share on other sites More sharing options...
abyssunder Posted March 28, 2018 Share Posted March 28, 2018 Once again, most of the corallites are too large for Pleurodictyum, even for P. americanum.
