Upper Pennsylvanian trip

Recommended Posts

Made a trip to the upper Pennsylvanian Bond formation today. I hadn't been to this locality in probably three years or so. I don't recommend hunting in 90+ degrees Fahrenheit.

I made some  slices from the top of the cut which is filled with microfossils, foraminifera. These aren't the best pics ,however, just using my cellphone so clarity isn't that great; there are some interesting little organisms hiding in there..

Holy cow, those are great trilobite parts! I love the creamy color as well.

Nice finds! (I wouldn't recommend it in 90+ degrees centigrade either.) :)

 

 

Mark.

 

Fossil hunting is easy -- they don't run away when you shoot at them!

I thought the same thing when I first read that!

Thanks!

I spent a couple hours grinding and polishing some of the micro slices from the top reddish layer and thought I'd sharesome examples.Echinoderm detritus, forams, etc. all very fine detail. Unfortunately,  what is not translating to camera are gossamer-like bryzoan webs but i can see them clearly in the microscope.These are all magnified  400x transmitted light.

Absolutely love the trilobite pieces. In my upper/late Pennsylvanian, they are usually black and fragile. Also the free cheeks on that cephalon really nails down the identification of one I have.

I haven't really seen a ton of info about these later Paleozoic trilobites as far as locales to hunt for them is concerned, so this is pretty interesting!

Every single fossil you see is a miracle set in stone, and should be treated as such.

Ameura missouriensis is the species I'm supposed to have here, if I have Ameura. I tend to think mine are Ditomopyge scitula.

 

Here is a study from the Pennsylvanian of Ohio if you have not seen it.
