2 years, 10 months ago2 years, 10 months ago@keith-peavy Paleozoic brachiopod. Mostly likely Cambro-Ordivician or Carboniferous. Still amazed your finding such great specimens considered the local lithology.

2 years, 11 months ago2 years, 11 months ago@keith-peavy My best answer is the the coloration is the result of either volcanism or metamorphic forces working upon the minerals in the rock to produce the luster you are seeing.

2 years, 11 months ago2 years, 11 months agoHey @keith-peavy ! This could be an igneous rock from some of the Carboniferous strata that is NW of Blommenholm.

2 years, 11 months ago2 years, 11 months agoGreetings @keith-peavy ! Could get a closer shot and provide a scale like a coin or ruler to get a sense of the size of the specimens you’re looking to have identified.

2 years, 11 months ago2 years, 11 months agoGreetings @keith-peavy ! This does look like the top of a horn coral. I am surprised you found it considering so much of the lithology around Blommenholm is metamorphic and igneous strata. There are some minor sedimentary members from the Cambrian and Carboniferous, so by rare chance this is perhaps where this erodes out of and flowed downstream.
