Lucid_Bot posted a topic in Fossil IDThis 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.
Pyrite Plants--Gold and Green
Lucid_Bot posted a topic in Fossil IDLast 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.
Glenshaw Formation Unknown
Lucid_Bot posted a topic in Fossil IDI 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 Doubt this is Identifiable, but,
Lucid_Bot posted a topic in Fossil IDWhat 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.
Pennsylvanian Nautiloids and Brachiopods
Lucid_Bot posted a topic in Fossil IDHello, 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!
Pennsylvanian Brachiopod Bi-Valve?
Lucid_Bot posted a topic in Fossil IDHowdy! 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.
Pennsylvanian Fern ID
Lucid_Bot posted a topic in Fossil IDHello! 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?
Lucid_Bot posted a topic in Fossil IDHowdy! 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 Don't See This In My Field Guide
Lucid_Bot posted a topic in Fossil IDI 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.
