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.
