PA Fossil Finder Posted February 21, 2013 Share Posted February 21, 2013 (edited) Are these forams? Found in Devonian limestone (I think). They are clear spheres about a tenth of a millimeter in diameter. They appear to have a black "nucleus" inside. Sorry, my images a terrible because they were taken through a microscope.

Missourian Posted February 21, 2013 Share Posted February 21, 2013 (edited) It's hard to tell. Do any of them have structure or fine details? Here are some of my Pennsylvanian guys for comparison: Triticites: Ammovertella: Two (orange colored), with ostracods and other things: Edited February 21, 2013 by Missourian Context is critical.

PA Fossil Finder Posted February 21, 2013 Author Share Posted February 21, 2013 It's hard to tell. Do any of them have structure or fine details? I'm not sure. They looked like they had very, very fine growth rings on some. Stephen Link to comment Share on other sites More sharing options...
Kehbe Posted February 21, 2013 Share Posted February 21, 2013 (edited) Here is a triticite I just took a picture of a couple days ago.

Shamalama Posted February 21, 2013 Share Posted February 21, 2013 Did you dissolve them out of the limestone or was it found in eroded debris at the base of a scarp? -Dave __________________________________________________ Geologists on the whole are inconsistent drivers. When a roadcut presents itself, they tend to lurch and weave. To them, the roadcut is a portal, a fragment of a regional story, a proscenium arch that leads their imaginations into the earth and through the surrounding terrain. - John McPheeIf I'm going to drive safely, I can't do geology. - John McPheeCheck out my Blog for more fossils I've found: http://viewsofthemahantango.blogspot.com/ Link to comment Share on other sites More sharing options...

Herb Posted February 21, 2013 Share Posted February 21, 2013 I do not believe they are forams.

PA Fossil Finder Posted February 22, 2013 Author Share Posted February 22, 2013 Did you dissolve them out of the limestone or was it found in eroded debris at the base of a scarp? I dissolved them out of limestone with vinegar (acetic acid), so they must be made of silica. Stephen Link to comment Share on other sites More sharing options...

PA Fossil Finder Posted February 23, 2013 Author Share Posted February 23, 2013 You can't see it in the photos, but these seem to structured to be grains of dirt or tektites. Are there an chances of fossilized bacteria? Stephen Link to comment Share on other sites More sharing options...

Are there an chances of fossilized bacteria? Bacteria is pretty small; electron microscope small. I can't make out anything on these that suggests an organic origin.
