I have no idea what this thing is. I found it in Allegheny County today in the Pennsylvanian Glenshaw Formation in what I think is Brush Creek Limestone. Unfortunately it is only part of the fossil, but I thought the pattern might tip someone off as to what it is. Scale is in metric. Thanks for the help.

This fossil comes from east Pittsburgh. I believe the formation is the Casselman, Conemaugh Group, Pennsylvanian. It looks like a worm to me, but what do you think? Thanks.

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.

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.

Hello, found what I think are nautiloids and brachiopods. I found the rock in a stream and I can't say what limestone (maybe brush creek or pine creek), but the area is Glenshaw Formation in northern Allegheny County, Pennsylvania. It's quite difficult for me to get good pictures, let alone good pictures with scale, so I'll tell you that the first two pictures are 2 cm (same organism), the second is 5.5 cm and the largest Nautilus in the last pictures is about 6 cm. All information is appreciated, thanks!

Howdy! Found this little critter today in Allegheny county, Pennsylvania. It is Pennsylvanian, Glenshaw Formation, probably Brush Creek Limestone. It's a bit different from the ones I'm used to finding and I don't see anything similar in my guides. It is approximately 1.75 cm x 1.25 cm. Even if it can't be ID'd I'd appreciate it if someone could tell me if it's brachiopod or bi-valve. Thanks in advance.

Hello! I have a few dozen plant fossils for ID. I'm going to go one at a time, but if you'd like to see them all, please go to the Members Collections section of the site with the link below. There feel free to offer corrections, specifications or confirmations. All are from the Glenshaw Formation. This first fossil looks like Pecopteris arborescens to me. What do you think?

Howdy! Split some limestone (I think it's Brush Creek) to find dozens of poorly preserved brachiopods and now I need some help IDing. Thanks in advance for any help. @cngodles

I just have so many questions, thanks for your patience. Found these two pieces in what, I think, is Brush Creek Limestone; they're definitely Pennsylvanian Period and from Allegheny County, PA. The first one is 3 cm x 1 cm, the second is about 2.5 cm long.
