    ID Help with Small Seed Fern

    Northeast Alabama. Pottsville Formation. Beautiful (and tiny) fern fossils I found a couple of days ago. I would love some help with an ID (or even someone to point me to a guide)! Photos are from my cell phone, but I plan on taking more with a better camera this week

    Fossil Sites in Western PA?

    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 just western PA but West Virginia and eastern Ohio as well.

    Mazon Creek ID

    I'm updating a display of Mazon Creek fossils that has been in our biology department for a long time. I would appreciate any help with identification and naming. (There were quite a few misspellings in the original display. I see one I missed - Asterotheca miltunii should be miltoni (or miltonii?))
  4. Let me start this off with I’m not looking for anyone’s hotspots or honey holes. I’d like to get out to hopefully find some fossil fern plants. Are there any parks in central to southern Maryland that have the possibility to produce any results in that general area. I know that studying and finding unique areas are part of the hobby, but I’m kind of crunched for time. My girlfriend loves the outdoors and hiking through the woods to look at all the variety of plant life that it offers. She thinks that my fossil collecting is cool and interesting, but she just isn’t into the fossils that come from animals. I’d like to find her some fossils that she would enjoy for a Christmas present. It would be greatly appreciated if there’s anyone that point me to a place where I can find her the perfect gift. I’m even going to throw in a pretty please and drop to my knees to throw in a little begging.
  5. I have a lot of unopened Mazon Creek concretions and though I do put some out in the winter for the Freeze / Thaw process, the vast majority, especially the larger ones do not open. So to dwindle my concretions, I have no problem whacking them with a hammer, and that is what I was doing today. As we all know, this is not the best way to do it since it can damage a nice specimen, but I take my chances. I always picked up any concretion that looked promising and never passed up larger ones. This all depends on the are that you are collecting, concretions from Pit 11 are never super large, but Pit 4 always produced larger ones - see below. Though these are large, they are by no means my largest. The vast majority of the time there is nothing inside, like the one below. Other ones produce something nice, like this Alethopteris that I cracked open today. Cleaned up_ A couple of my other finds from today, nothing spectacular, but is nice to get rid of the dud ones. Neuropteris Annularia Annularia, Neuropteris and Bark Asterophyllites Bark Essexella asherae Jellyfish
  6. Was able to visit Chicago over the 4th to visit a friend and just managed to sneak in (between torrential rains and everything else to do in Chicago) 4 hours or so of collecting at a site in the Mazon Creek. A few of the concretions have now opened nicely and hopefully more are on the way. First, have to very sincerely thank the Chicago-area Fossil Forum members who were unbelievably generous with their time (and in many cases, their fossils!) and who really helped a total Mazon novice have a successful trip! Here are some of the first finds, with lots more currently in the freezer including a whole bucket of Pit 11 material that was super generously given to me on my way out. Hopefully some more interesting finds await! The next weekend I also took a short trip to a site near Wheeling, WV composed of slate-like rocks in a pretty nice roadside stream that had great scenery and a lot of butterflies floating around. I didn't find a ton aside from one OK (broken) fern frond and some nicer hash plates, but it was a fun trip! And then lastly, I was able to clean up a few more finds from Centralia that are looking good, will likely return to that site soon. A question: is anyone familiar with any reasonable East-Coast sites for Mesozoic plants? I'm planning to investigate some streams in College Park, MD (luckily quite close to home) and then I've done some research on Triassic sites in North Carolina but I'm a little nervous about driving all the way down just to take a look. If anyone has any likely leads they would be appreciated Otherwise I will continue to update this thread as more things pop open from the freezer!
  7. On Sunday, I finally went again the Mazon Creek and later a Bond Formation rock formation of Pennsylvanian age, around 300 Million Years ago, in Braidwood, Illinois and Oglesby, Illinois with three friends after some scheduling adjustments. The trip was awesome and we collected a pretty impressive fossil haul. At Mazon Creek, We mainly hunted for fossils around the shores of local power plant cooling pond (which despite apparently having water temperatures that day of 100 degrees Celsius, still had a decent amount of birds resting on-top). We saw also a large rock pile on the other side of the lake, which we tried to get to on foot, but after an hour of walking decided to head back and try our luck next time. We then went to Oglesby. I'm still cleaning most of the Mazon Creek fossils, so for now I'll be showing my and my friends findings from the Oglesby site. It was pretty hot and got a little cut up on the rocks, but the fossil haul collected was awesome!!! Small jumping spider we found at the Oglesby site. A piece of either coral or Brachiopod one of my friends found in Oglesby. Anyone got an ID for this specimen? Pretty Impressive Crinoid Stems collected as part of the day's Oglesby fossil haul!!! But this next specimen is probably one of my favorites from this recent fossil haul. It's a partial Ctenacanthiform tooth tip (Possibly Gilkmanius sp.) on a limestone slab with some brachiopod fossils also attached (of which I put it recently under a dissecting scope). Based on the thickness and size of the tooth, the shark it came from must of been a pretty decent sized animal when alive!!! A pretty descent Neospirifer brachiopod specimen!!! This next specimen was truly an unexpected find for myself as I've seen a Ctenacanthiform tooth from the bond like this in person before (most I've collected and heard about are of a black coloration where this is a mixture of black, grey, and brown). I must say it's very beautiful and definitely from a Ctenacanthiform shark!!! But I'm curious as to what Ctenacanthiform species it could've come from? Any thoughts on its ID you guys?

    Shinarump swamp

    Newbie here, Have found an area of what must have been a low. dampish area of the shinarump. The matrix is a dark mudstone with little conglomerate. It sits on hard reddish sandstone which I assume is Moenkopi. Pictured (first two) is a partial female cycad cone and a cycad top (next three pics) with the trace where a male cone passed through. I have found many other plant fossils in this same immediate area and will post as I indentify

  11. Starting in early 2021, I've been going fossil hunting at the Mazon Creek area in Grundy County, Illinois. The site I visit the most so far is the fairly large Mazonia-Braidwood State Fish and Wildlife Area. After advice from other members of the Fossilfourm, I've decided to put the nodules I'm most curious about under the microscope and dissecting scope! With these better photographs, I'm wondering if anyone could give a proper ID for these specimens?
  12. Starting in 2021, I've been going fossil hunting around the Mazon Creek area in Grundy County, Illinois. The site I visit the most so far is the fairly large Mazonia-Braidwood State Fish and Wildlife Area and at first, I would barley find anything. Then after visiting Monster Lake and another secret location in the area, I started finding more fossils. However, most are around 2-7 cm. In length and I'm still having difficulty getting IDs for them? Would anyone be able to help ID them? I think this could be some sort of Chondrichthyan or a lobe finned fish? Maybe part of a dragonfly wing or a plant? Plant fossil - Genera unknown currently? I don't know what this could be? The specimen here looks almost like a plant fossil. Worm fossil - genera unknown currently.

    Pennsylvanian Fern ID

    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?
  14. Hello everyone! I had a fun a really fun trip last weekend with some friends, including @Jeffrey P. We hit a fern ferns spots I've found over the years, and got access to another spot I never explored.. overall, it was a good trip with good friends. Here are my favorite finds...
  15. For the last 4 years I have been collecting plant fossils from sites in East Central Illinois. These fossils were all brought to the surface by underground coal mining in the first half of the 20th century. Most of the spoil piles in the area have been graded or flattened out, but a few still remain, standing tall above the flatland. One particular pile is, I believe, the source of most or all of the fossils I find. The shale that makes up the spoil has been fired by the internal heat of the pile, resulting in the hard, reddish material known as "red dog". This shale is then crushed and used as paving material, on trails, parking lots, and construction sites in the area. It's at these secondary locations that I am able to search the material for the impressions of ancient plants and collect them. The shale is pretty smashed up, so complete or large fossils are rare, but the preservation of detail is generally quite good. Geologically, the fossils come from the Energy Shale Member of the late Pennsylvanian Carbondale Formation.

    Mazon Creek 8-28-21

    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 the unopened concretions may be hiding. A few close ups: No clue about these last 2, the 2nd may just be worn and isn't the center plane so I will probably try to freeze/thaw it. It was nice being able to get out and chat with others while collecting and learning about a new to me location. Special thanks to @connorp for putting up with all our questions.

    Five MC searching for identity.

    A couple of head scratchers and three that I would have called Pecopteris in the past. Calling on the usual MC gang @stats @deutscheben @bigred97 @Nimravis @fiddlehead @flipper559 @connorp @RCFossils and anyone else who would care to take a stab at ID.
  18. Dendrites are moss- or tree-like pseudofossils on the margins of rock fissures and fossils, usually on the bedding surfaces of platy limestones and sandstones. Mineral-rich water with high concentrations of iron and manganese has penetrated microscopic cavities between limestone layers, and diffusion-limited growth has created these brown iron and black manganese dendrites, which are often mistaken for fossil ferns or fossil moss.. This slab with manganese and iron dendrites comes from the lithographic limestones of Solnhofen.
  19. (First post so sorry if there are formatting errors) Yesterday I took my first fossil hunting trip ever and had some beginners luck! I went to Cory’s Lane in RI and stayed for about an hour and a half. I found a few pieces (pics below) that I’m really proud of. I’m not sure if the large one with big lines in it is a fossil so if anyone knows that would be great. All that said, I still have no idea what I did right (or what I was doing wrong). Some members told me that I should go for the dark grey shale and not the graphite-black stuff, which I tried to do. I was also told gentle digging would produce shale that may hold better prints but didn’t have a shovel with me. I definitely intend to go again so any tips on improving my technique for that site would be appreciated. I was also wondering if there is a way to tidy these up/make the imprints stand out at all? I looked at some posts about PVA etc. but those seem to be techniques for museum-grade pieces (which I know these aren’t). Also the first picture has lots of what I assume are rust stains and I was wondering if it’s possible to remove those without destroying the prints?
  20. While visiting in Rhode Island recently, my wife and I spent a few hours on the beach at the end of Corys Lane in Portsmouth. While it isn't one of the most productive sites I've had the pleasure of mucking around in, I always feel at home at the edge of the sea. It's a bit of a challenge to find any reasonably well-preserved fossils here, but the challenge just makes it all the more enjoyable. While my wife wandered away, deserting me once again for the lure of an ocean beach, I spread out a square of 4-mil plastic in the always futile attempt to keep the graphite-infused beach gravel off yet another pair of too-good-to-throw-away jeans. The overburden of beach-tumbled shaly gravel and slipper shells (Crepidula) was only 6-inches (15cm) deep here, blanketing a promising layer of Pennsylvanian age shale. Thankfully the tide was low and I could dig without the need to drain water out of the excavation. Regretably, I left my phone/camera in the car and have no current photos to share today, but here's one I took a few years ago: I've had mixed results here at this site, with nothing worth keeping on occasion. This day's finds were slightly above average, by my reckoning. Most of the shale I was uncovering was much too fragile to recover any recognizable plants, but after prying out and splitting a few solid slabs I did come home with some rather nice pieces, even if the preservation wasn't quite as good as I would prefer. I haven't been able to identify these seed ferns. Maybe a species of Pecopteris? The details just aren't preserved very well. The preservation is better in this harder rock. I think these are Cordaites principalis leaves. And a couple additional unknowns: The best find of the day, a modern skull, was found, of course, by my wandering wife. I believe it was formerly put to use by a sea robin (Prionotus carolinus). It was a good day.
  21. I've spent some time gathering at the plant layer locally. I was able to pry behind the layered shale and pull out some larger pieces unbroken, and also split them. The layer is a delight, just about any piece I recover has some sort of plant impression on it. Immediately below the layered shale there is a more nodular type of rock that no longer breaks apart in neat and tidy planes. So whatever environmental change happened, it happened right at this layer. The first one was a really long and well defined fern frond. The carbon is all still in place. I want to create a parallel cut to remove this part of the specimen, then catalog and store it. I am hoping I can do so in a way that won't dust over the carbon and degrade it. The rock that covered this was a physical impression of these leaves in the rock. It appears more could be exposed at the bottom, but it's not easy to do. The second specimen is a preserved fern frond with very tiny leaves. The larger leaves stick out, but a more complete arrangement like this is very pleasing to look at. The iron staining at the bottom creates almost a work of art. This specimen has a small root or similar structure at the bottom right of the photo. There are repeating points towards the bottom with larger circular structures at the top. These huge fern leaves showed up right before I was done searching during this particular session. Both sides are shown. It would be interesting to know if it continues on in the other direction.
  22. Imagine working for a year in a small college science department and there was a room you vaguely knew was there but didn’t have the keys to and never saw anyone going in or out. Then one day, campus grounds workers open the door, and you inquire what is going on. You discover it is an old earth science storage room (earth science hadn’t been taught there in many years) and everything is to be discarded the next day into the dumpster to make room for some new purpose. It’s a room about 15 feet by 20feet packed with boxes on shelves filling the space up to the ceiling. It is a dusty disordered mess. You don’t have the authority to put off the clean out. What would you do? Exactly, cancel all plans and stay up all night sorting out the room and triaging the best stuff. So that’s what I did. Not heroic like running into a burning building to save children, but someone had to do it. Even with several trips I could only take a small percentage of the material but most of the fossils. Most were labeled, some had numbers on them but there was no accompanying key, and many had no identification at all. Perhaps 2% of the material was fossils, and it was scattered throughout the room, like some sinister easter egg hunt with every minute ticking down until the morning workers showed up. Here then, are some of the unlabeled and unidentified fossils I recovered. Some are obvious, others less so. I thought TFF members might have some fun with this. # 1
  23. I took a half dozen trips out to Schuylkill County this summer with the kids. We looked through Mohantango and Llewellyn rocks at various locations. These are some of my personal favorites:

    McAdoo PA

    Found with the typical ferns found at McAdoo. Is this a seed (or spore) or just some kind of concretion?
