Hi. The geological info for this find is: Pennsylvanian (Carboniferous), Conemaugh Group, Glenshaw Formation. I've been digging at an outcrop near a local stream and finding a lot of pecopteroids, neuropteroids, calamites, some sphenopteroids and possibly lepidodendron/stigmaria, sigillaria and cordaites. Recently the rain washed away the dirt at the base of this outcrop. Cutting away the rock at the base I found at least a dozen instances of these somewhat cylindrical and flat-topped and flat-bottomed rocks sitting one on top of the other. The first picture shows a cavity from which I removed

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!

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

Here's a new find from the I&M trip last weekend. The nodule was full of indeterminate plant fragments, and I almost tossed it until this one small bit (~1cm in length) caught my eye. Maybe a wing fragment or am I being hopeful? The texture is much different than what I've seen in plants, but that's a bit hard to capture in pictures. I can try to get better pictures tomorrow in the sun if needed. As usual, any thoughts are much appreciated.

Fossil Forum members were well represented at the Illinois Canal Corridor Association's Mazon Creek collecting event this weekend. My wife and I were able to make the 11 hour drive out Friday to join them and we enjoyed a productive afternoon in the creek Saturday gathering several buckets of concretions to take our first crack at freeze thaw. We also found a number of already opened specimens to wet our whistle while we do our best to be patient. Here are some of our better finds even if some are a little water worn. New to us, so the trip is already a success regardless of what

Greetings, I’ve recently gotten back into prospecting fossils and I’m looking for some suggestions on sites to visit in western Pennsylvania. I frequently visit Ambridge PA to find fern and Calamite fossils from the Mahoning fm and would like to find more. I also would like to find fossils of early Permian (tetrapods, plants, or invertebrates). I hear that Washington county (south of Pittsburgh) has some great spots and would like to know if it were true. I also would like to show some of my findings from Ambridge as well. Note: I’d like this to be suggested places not j

Here are two interesting Mazon Creek flora nodules that popped yesterday. I believe they are both assigned to Rhacophyllum. If so, I am excited, I have not come across this "genus" before. Rhacophyllum cornutum Rhacophyllum fucoideum I am pretty confident on the IDs but confirmation is always great. I am quite interested however in the second specimen. It appears that there is a root-like structure emanating from the central base. I cannot find many images of R. fucoideum online so I am not sure if this is significant or not. As usual, any though

Pennsylvanian (Llewellyn Formation, 308-300 MYA) plant fossils from coal mine tailings near Mt. Carmel, PA.
fossilcrazee posted a topic in Fossil Hunting Trips
This was, essentially, a quick scouting trip based on threads on the Forum. Don't know much about these fossils but wanted to confirm the location and density of Pennsylvanian (Llewellyn Formation, 308-300 MYA) plant fossils from coal mine tailings near Mt. Carmel, PA. (NOT St. Claire, which is closed to collectors). There were abundant specimens, many bearing evidence of pyrite replacement: orange stems and plant hash. There was also some evidence of pyrite replacement by pyrophyllite to yield silver-colored films. Against the black matrix, the silver-film plant fossils are beautiful and,- 7 replies

REMPC P0021 Fossil Fern Macroneuropteris macrophylla Carboniferous, Late Pennsylvanian Llewellyn Formation, Bear Valley Strip Mine Coal Township, PA, USA -
A few weeks ago @Jeffrey P and I met up in Eastern Pennsylvania to collect plant material in the Late Pennsylvanian Llewellyn Formation. We started our day at Centralia and then made our way to another site. I have visited Centralia a few times now but Jeff had never been there before. Our hope was to find Jeff a nice Trigonocarpus seed but unfortunately our efforts did not come up with anything. The pickings at Centralia were rather slim. However, we did see in-situ a large segment of Stigmaria ficoides root with rootlets. I ended up only keeping a few finds. The firs

Need Help With Woody Structures from Glenshaw Formation: Mahoning Shale of Western Pennsylvania
minnbuckeye posted a topic in Fossil ID
I had the opportunity to collect plant fossils in Western Pennsylvania a few weeks ago. Success was had IDing the fern leaves. But I am having difficulty identifying the woody pieces found that are not Calamites. These came from the Glenshaw Formation, Mahoning Shale which is Pennsylvanian. I realize that a decaying swamp is full of twigs that likely are unidentifiable, but there seems to be structure in at least some of these which could lead to some sort of identification. I am hoping those knowledgeable with the Pennsylvanian flora can chime in. 1. Here are some larger pieces -

I'll update this thread with my Mazon Collection over the next few weeks. With some good weather out yesterday, I managed to get my first fossil hunt in for the season and will post a report in this topic. I will be moving this upcoming summer which will put me even further from Mazon Creek so I have purchased a few pieces to fill in the genus/species I haven't found yet and will mention if I purchased a fossil. I still hold out hope to find some of these pieces I purchased eventually but will realistically be difficult if I only can make 1 trip a year. Fauna Tullimo

Mystery Piece Found Along With Edestus Teeth Illinois Coal Mine Carboniferous
Kurufossils posted a topic in Fossil ID
Hi all, this strange piece came with a batch of edestus fossils that were found in a coal mine in Illinois. Have no idea what it could be, the front seems to be coated in black coal mostly while the back has what appears to be ridges. All I know about the location is it was found in a coal mine along with some edestus teeth that is Carboniferous in age. Hoping with some help to get to the bottom of this mystery. -
I am somewhat hopeful that this is an example of Amynilyspes (a pill millipede), but would like to get another opinion. It was found open and is a bit worn. @Nimravis @bigred97 @flipper559 A close up of the "tergites"

Hi all, Recently going through some of my Stark Shale material and prepping some of it and this little specimen has me wondering if it’s a tooth. It’s probably pareidolia but the lip at the bottom appears to have a sort of smoothness to it unlike the two protrusions. I'm not sure if the honeycombed structure is bone or cartilage but I’m trying to decide if I should prep it any further and any ideas or thoughts would be appreciated. @Petalodus12 @connorp 1. 2. 3. Thanks!

Hey everyone, scrabbling around Santa Fe and found a nice spot with tons of shells and some crinoid stem parts, when I came across a round piece I thought at first a vertebra. The next time I went out with a friend she found some points and we found more smaller pieces and thought some kind of snail, but not an obvious twist. now I'm leaning toward a mineral formation? Any help would be awesome. Last picture is a shell to give an idea of the surroundings...

This weekend I was able to spend a couple hours breaking rock at one of my favorite Pennsylvanian sites. This site exposes the lowest units of the Carbondale Formation, from the top down: Mecca Quarry Shale (MQS), Francis Creek Shale, Colchester No. 2 Coal, paleosol. At various times both the St. Peter Sandstone and Platteville Group (both Ordovician) have been exposed at the bottom of the pits (they were not visible this trip), representing a major unconformity in the area. The concretions from the Francis Creek Shale (i.e. Mazon Creek fossils) are not productive here - my area of focus was i

My folks have a nice lake behind their house. It is relaxing to spend a warm evening watching a heron spear fish or geese fight each other. Or watch silt slowly fill the lake bed. Across the street, a housing developer stripped off a bunch of soil down to the bedrock, but ran out of money before building on the land. This has resulted in some significant erosion and sedimentation in the lake, but this cloud does have a silver lining. I soon noticed a thick bed of shale exposed on the hill. So it was only a matter of time until I make the short trip to the top. The hill,

On Saturday I took a trip to collect some Late Pennsylvanian plant material from the Llewellyn Formation of Pennsylvania. I am still working through my finds and identifying everything, but as an initial matter I had a question about two pieces. I have a guess on what they can be and was hoping someone might be able to confirm my suspicions. Any help is greatly appreciated. Thank you! First, I believe that this fossil preserves the cell structure of a Calamites stem Second, are these the terminal shoots of Asterophyllites? Unfortunately some of it broke in transport b

Blair County Pennsylvania (USA) (Private property) ..... Recently I explored some heaps of old mine talus which I think is the whitish sandstone from the Pottsville Formation. These rocks commonly have imprints in various degree of detail, especially cordaites and lycopods. The pics below show one large boulder with what I think is a very large imprint of sigillaria. The tape shows 8 feet. I'll readily admit that I'm a noob and susceptible to seeing what I want to see. From my pics someone who knows 'way more than I will ever learn opined the "ridges" ar

From the Atrasado Formation in San Diego Canyon, New Mexico. Took a couple of younger friends fossil hunting, and we found a good bed. This one's a real beauty. My photographic equipment is primitive and doesn't do it justice. Graptolites and something else. Not sure what the circular structures are; I don't have the equipment for proper microphotography. There is a very clear echinoderm plate elsewhere in the sample so I'm wondering if these are some kind of echinoderm. They're very clear under the loupe and obviously f
