Howdy! This specimen comes from the Pennsylvanian Period, Conemaugh Group, Glenshaw Formation, in the Mason Shales below Brush Creek Limestone. The area has a lot of Pecopteroids, Neuropteroids and Calamites. However, I've been informed that it is not Calamites. I should also note that this piece was part of a larger fossil cast that was crumbling apart when I found it, and unfortunately, I was unable to save the rest of it. The last picture is the back side. All help is appreciated and thanks in advance!

Howdy! I found a beautiful pseudorthoceras last week and last night I noticed a tiny white organism on the rock. It looks like several "Vs" strung together. Fossil is 0.5 cm, is from the Glenshaw Formation and likely Brush Creek Limestone. I have no idea what this thing is. Thanks for the help.

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.

I am going to start adding some images of my favorite finds which I call Collection Pieces. Identifications range from maybe, probably to most likely. I've only started to seriously collect over the past year. I've spent a great deal of time studying and learning Geology, as a hobby. I am located in Western Pennsylvania. At first, a map of the area. Anything in bright yellow is the Glenshaw Formation. The Ames Limestone layer exists between the Glenshaw and the Casselman Formations, which is the Orange color on the map. I have yet to explore the Ames Limestone, so I've only found f

I've had this for quite some time, I thought it may have been a gastropod. But I'm now very convinced I have an ammonoid. They are very rare over my way, they didn't like coming into the geologically temporary shallow sea bays that formed. We have many Nautiloids, but not many Goniatitids. I've considered Pennoceras and Mangeroceras. The former is reported from rocks of similar age in Ohio, but the shell ornament has me considering the latter. The growth lines curve back towards the posterior at the dorsal-lateral shoulders. Anyone from the mid-continent (who are swimming in ammono

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.

I was rooting around in Ambridge, Pennsylvania, Beaver County yesterday and found some interesting plant fossils. They are Pennsylvanian and out of the Glenshaw Formation. Not sure if they're identifiable or if I would need a microscope to ID. Any help is appreciated.

Howdy! I've been hunting mostly plant fossils in the Pittsburgh area for about two years. This is a sampling of some of my favorite pieces. I hope you enjoy! All are Glenshaw Formation finds. 1. Neuropteris fimbriata 2. Metacoceras 3. Metacoceras 4. Asterophyllites 5. Lepidodendron obovatum 6. Neuropteris Ovata 7. Crenulopteris acadica 8. Brachiopod, Linoproductus? 9. There are over 50 little fossils on this pla

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?

One of my local spots to fossil hunt has a lot of limestone (I think) with what looks like worms running through it. I see this stuff everywhere and have no idea what it is. The area is definitely Glenshaw Formation and has fossiliferous limestone and shale. Any help is appreciated.

Howdy! Pried what looks like a branch out of some shale today. I was hoping someone could confirm for me that this is petrified wood and possibly ID it. Lots of tree fern leaves and stems in the area. Additionally, the fossil seems unusually heavy. Thanks in advance! Pennsylvanian Glenshaw Formation.

Hopefully I'm not breaking any rules here posting a link. I spent my weekend finally putting my catalog into a proper database, and creating a user interface for it. I used to use Google Sheets, which is pretty great. If I wanted to, I could use them as the source of data, but I decided to create a proper MYSQL database so I can keep relationships across tables, such as the stratigraphy of particular find locations. I have many more improvements coming for it, but it is at least functional right now. Everything from CG-0001 to CG-0161 is from the Glenshaw Formation, Conemaugh Group- 6 replies

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'm chipping away at what I think is brush creek limestone to find what I think is Mooreoceras (first two pics) and Metacoceras. I have no idea what the last fossil is. All help is appreciated, thank you.

Hello again, I found these tiny specimens today, and I'm not quite sure what they are. If I had to guess, I'd say the spiral shelled creature is Amphiscapha and the more clamish one looks a bit like Kozlowskia without the little side wings. No idea what the last one is. As always, all help is greatly appreciated. Also, sorry about the bad pics, these are quite small specimens.

Whatever this fish tooth is, I've never found one before. I had a small sliver showing in a rock and spent over an hour slowly air scribing over it and getting it to this point. I'm hesitant to go much further, as I may break it. I considered Polyacrodus for the shape, but I see none with the pitted pattern that this has. Tired of trying to ID Pennsylvanian fish teeth yet, @connorp? Maybe this is another paver type teeth from a ray, etc. For scale, the length of the tooth in the first photo is 13 mm.

Howdy! Chiseled this out of a rock today. I thought it was a coral at first, but not quite sure now. The final picture is a cross section of the inside. Thanks in advance.

I’m thinking this is Stigmaria. Scale bar = 1 cm. Found in the shale below the Brush Creek limestone, a zone with many plants.
