Please help identify this fossil

Hi everyone! Today, a friend of mine from the Paleontology course at the University of Bristol and I went fossil hunting at the beach of Portishead, as we had heard it was an interesting and productive location. We were fairly confident that we would come home with at least some crinoid pieces, as these were meant to be rather abundant, but our real goal was to hopefully find some of the elusive eurypterid remains. It was about half an hour bus ride from the center of Bristol to Portishead, so it's relatively quick and easy for us to get there. It didn't take too long for us find our first few crinoid pieces in the rubble on the beach, and my friend managed to find a couple of decent spiriferid brachiopods by splitting some small rocks open. Unfortunately, it started to rain quite quickly, and after about an hour of searching the rain we decided to call it a day... so we didn't hunt for very long at all and hence didn't make any impressive finds. We didn't see any traces of fishes or eurypterids either which was a little disappointing, although also somewhat expected. Wishing to escape the rain, we found a little restaurant where we could sit inside and get a warm lunch, and afterwards we decided to just go back home as we were both tired, despite the very short hunt. So in terms of finds, we weren't very successful, but I did manage to snap some nice photos from the location. The geology of the place was really crazy and kind of all over the place, as you can see from the pictures here. Really interesting! We haven't yet covered this topic in my Geology course, but I suspect we will do that sometime soon, and then I will probably be more knowledgeable about what we're seeing actually means. But for now you'll still have to stick with my very amateur descriptions (stratigraphy can be a little complicated for a Pleistocene hunter as myself! ) This is the northern end of the location, Battery Point, where we are looking at several layers of the Portishead Formation. This is a Tournaisian-aged (Mississipian, early Carboniferous, approx 350 million years old) formation that is very rich in crinoids and corals. What's interesting to note is that the layers are not straight, but sit at approximately 30 degrees upwards. But that's pretty mild compared to the Devonian layers (as you will see a bit later).

Identification Help from Mazon Creek, Pit 11 (Arthropod appendage?)
Thomas.Dodson posted a topic in Fossil ID
Hello all, I have been a long time lurker of the forum (simply reading has been helpful enough these years) but have finally decided to request identification help on some fossils. I spent the summer conducting research in Illinois and spent my spare time collecting fossils. I was fortunate enough to collect Mazon Creek fossils about 14 years ago on a trip so I was thrilled to finally return to the area and collect at the Mazonia Braidwood Fish and Wildlife Unit. I have Key to Identify Pennsylvanian Fossil Animals of The Mazon Creek Area as well as Jack Wittry's The Mazon Creek Fossil Flora and these have been very helpful in identifying specimens but this one has thrown me a bit. As for the fossil, it resembles an arthropod appendage (like a Eurypterid walking leg) but I might be blinded by my wishing it to be that. I appreciate any help and insight from people more experienced with Mazon Creek. I will likely post more unidentified material from Illinois and Missouri soon. Thanks for your time. -Tom- 19 replies

I have this fossil here which at first glance I perceived to be some kind of seed, however I’m not sure. These are both from the same individual, just the positive and negative sides. It is just shy of half an inch long. It was found in the North Attleboro section of the Rhode Island formation

From the album Plants of the Lewellyn Formation
Early Conifer Fruit/Seed Body about 4" long Pennsylvanian Age (308-300 MY) Lewellyn Formation Columbia County, PA The impression is coated in white iron oxide left from original plant material during fossilization. -
Ya know, I'm great at plant identification if it's currently growing in my region. Dive back to the Paleozoic and I can tell Calamites from Cordaites, but that's about my limit without a book in hand. So far, I've had 8 and I still don't know what this is! I'm pondering the frond-like object running diagonally across the center of the picture. It looks like a fruiting body from Cordaites, but it lacks the sporophyll. It also resembles Corynepteris angustissima, but the only illustration I can find lacks sufficient detail. This came from a mid-late Pennsylvanian Lewellyn Formation exposure in Columbia County, PA. It's about 4 inches (10cm) long.

I found this in a phosphatic nodule from the Mecca Quarry Shale (Middle Pennsylvanian) of Illinois. It's pretty jumbled, perhaps as a result of digestion. My first reaction was that this is the base of a fish tooth, but I am not positive. Any thoughts?

I need help with this one. Ive been searching the internet; but there is precious little works on Lower Mississippian bivalves. So I thought Id turn to you guys either for an id or to point me in the direction of an expert in such things. Its from the lower Mississipian epoch of the Carboniferous. The Fort Payne Chert, the black shale member (not sure if that has a name.) Its fairly large for a bivalve from this time period. Im not sure if they are related but Ive also been finding these. I believe its also a bivalve but I havnt found more than one valve. They are a lot more common than the bigger one. With the similar concentric ribs, they may be younger versions; though the overall difference in shape makes me doubt it. I appreciate any help you can give me.

I found this rock alone under a tree, so I'm pretty skeptical of it, but I'm also pretty curious. I looked up trace fossils that might look like this, and I thought it was pretty similar to Rusophycus. The rocks around it are from the Glenshaw and Cassleman Formations of late carboniferous Pittsburgh. The "print" is about 10 cm long in its entirety, and maybe a quarter cm deep or so. Could this be a print of sorts or is it just some funky weathering? Thanks!

I found this near a small creek in the Casselman Formation right outside of Pittsburgh. It was originally covered in some sort of black matrix, most of which I scraped off. It really looks like a piece of bone (maybe a tibia or a radius?) to me, but I might just be crazy. Thanks!

Im guessing this is simply mineralogical, but I thought I'd put it up here to see what you guys think. Its an ironstone concretion from the lower Pennsylvanian. Its shot through with calcite, but its the black bits that are making me think it may actually be something. A close up of the interesting area.

Last fall, I drove out to Centralia, PA, the famous burning town. The coal vein below the town caught fire, creating random sinkholes filled with toxic gasses. The town was abandoned. The buildings were bulldozed. Only the most foolish set foot in the town limits. Today, however, the fires have mostly followed the coal vein out of town. I was out once in September, just to check the lay of the place, then returned in October to find fresh "No Trespassing" signs. Darn! Six weeks ago, I got a report that the signs were down. The person making the report said they double-checked with the locals in the next town and were told that yes, it was fine to go fossil hunting out there. So, today my hubby and I went to investigate. The signs were indeed own, replaced two with Keystone State logos. One banned motor vehicles. The other announced that the property owner agreed to allow game hunting but a permit was required. That was it. In we went. The fossil outcrop is part of the Lewellyn Formation, which also runs through the now-closed St. Claire site. Lepidodendron, calamites and cordaites cover almost every inch of the shale. The impressions are coated with shiny, black graphite, white pyrophyllite and kaolinite, plus some bits of other colored iron oxides and even some shiny pyrite. If you go, be warned that the slope is steep and treacherous. I used rock climbing gear so that the scree didn't slide out from under me, sending me sliding fifty feet or more down the hill. The woods at the base are navigable, if a bit tangled in spots, and are littered with everything that weathered off of the slope, including occasional large hash plates.

Very large Carboniferous caniniids can be spectacular - here is an 8cm section of Siphonophyllia ?cylindrica from Benbulben Mountain, Sligo that I just acquired for a small amount in an auction (nobody else wanted it, surprisingly!). Also a pair of pieces from a very similar species, from the Sligo coast - another bargain from a while back, probably Siphonophyllia samsoni which is slightly later. (Both are Asbian stage, lower Carboniferous). They can be up to a metre or so in length. I must go there one day! (Section photographed submerged - the hand held shot shows the difference in clarity from this method, as well as the size.) scale bar 1cm (I think the section shots are worth clicking to magnify.)

Hi all, I found this piece of mudstone at Besom Hill in Oldham, near Manchester. The rocks here are Upper Carboniferous in age. One side has unusual lineations, but not the type caused by bedding as seen in the shales that are very common in the area. The reverse side is typical of the mudstones found here. I'm thinking it's a fragment of Walchia trunk, though there isn't any mention of Walchia in any literature or by any other collectors. Does anyone have any suggestions? Cheers Yuanls

Found out I had fossils down the street from my house and did some searching for a variety of plant fossils. This was found in a road cut along the Ohio river near Ambridge/Aliquippa, PA and the fossil layer is the Mahoning Shale. Most of what we found were tree ferns, calamites and lycopods. We had some great success and it was great to find these right down the street! Most were easy to ID with help from the Fossil Guy site. But we can't find any info on the attached. Any ideas are welcome!

Found this small oddity while breaking apart limestone. The pitted appearance was interesting. The pits also seem to extend the whole way through. They also appear to wrap at a 90 degree angle on the side that isn't broken. The broken side reveals how they go through. I chipped away a little at the matrix, but didn't go too tough to keep from breaking it. Whole specimen with scale: (stacked photo) Showing outside 90 degree wrapped edge with same appearance: (stacked photo) Broken edge showing channels going through the width. Additional view of the top (unstacked photo)
