Unknown Microfossil from Pennsylvanian aged Excello Shale in thin section
Samurai posted a topic in Fossil ID
Hello! I was making some thin sections of some material from the Excello shale and found a very large and bizarre structure. Sorry in advance it was too big for my microscope camera to really capture it all, but here is the specimen in question its most likely coated in apatite/phosphate? along with small radiolarian/sponge spicules surrounding it I sent a photo to my professor and he said it could be something new but he would have to see it in person (he is an expert in Radiolarian microfossils) I wanted to post it here and see i-

I’ve been reading up about fossils in the Eastern PA region and came across a few papers about vertebrate fossils. Are any of these sites still accessible ?

I found some pyritized plants a few days ago and noticed that one looks like a stem with seed pods. The fossil measures 2 cm and is from the Glenshaw Formation of Beaver County Pennsylvania. I'm nearly certain that what looks like a stem is a stem, but what are the three round things seemingly attached? Help is appreciated, thanks.

Found what looks like a tooth fragment last week. I've only ever found Petalodus teeth in this formation and it doesn't quite look like those. There are no serrations on the fragment. This was found in Allegheny County, PA, is from the Glenshaw Formation and is probably out of the Brush Creek Limestone.Thanks for the help.

Last week I was hunting in my usual location in Allegheny County Pennsylvania (Glenshaw Formation) and found that several of my specimens have splotches of what appears to be pyrite crystals. With some of the broken fossils I could see that even the insides contained gold-colored pyrite. On the other side of these plates were what looked like rootlets covered in a pale green mineral. Is this pale green mineral pyrite as well? Is there some way I could test this? Thanks for the help.

Howdy! I'm finding some beautiful stuff digging in the Glenshaw Formation of Allegheny and Beaver counties. Hoping to find out/confirm what they are. The limestone finds I believe are from the Brush Creek Limestone. As usual, all help is greatly appreciated, thanks! Side view of Wilkingia? Never saw round leaves before Spiropteris? Sigillaria bark? Some sort of bone or root of a Petalodus tooth?

I found this piece in my back yard a couple of years back and I still don't know what it is. It is Pennsylvanian, Glenshaw Formation and from Allegheny County, Pennsylvania. Thanks in advance for all help.

Some gastropod specimens I collected in Western PA. in December in calcareous shale (Ames Limestone- Pennsylvanian) . Can you help with the genus IDs? Thanks.

Found these, my first Pennsylvanian Age marine fossils in calcareous shale in a road cut in western Pennsylvania on a recent trip. According to the Fossil Collecting in Pennsylvania guide, the formation is the Ames Limestone. Any help with IDs would be greatly appreciated. Thanks. 1.)

Found this piece in the Mahantango formation of Pennsylvania. I believe the one thing to be a bivalve or brachiopod but I’m not sure. Also, any ideas on the little orange thing? It’s not a Crinoid but I can’t determine what it is.

Hi, I don't have any information on this specimen since I believe the rock that I found it in is foreign to the area I discovered it. Although I think the rock is from somewhere around the Western Pennsylvania/Eastern Ohio area. It is approximately 2.6 cm by 2 cm. Just hoping someone has some idea what it is. Thanks again.

What do I know? This piece is Pennsylvanian and probably from Brush Creek Limestone. It was found near marine fossils. I have no idea what it is. All help is appreciated.

I was searching around a local stream when I found some limestone with dozens of crinoid stems. I can't say what the formation is as I think they rolled down a hillside which had foreign limestone blocks to prevent erosion. If they are native, they would be Pennsylvanian Glenshaw Formation. Each of them has stellate lumens and many have a pinkish hue. Can anyone tell me what variety of crinoid and is it possible to discern the period? Thanks.
