  1. I have found that illuminating photos of cordaites fossils are relatively hard to come by. Hopefully these images will help to rectify the situation. Photos 1 and 2 are of a Cordaites borassifolus Sternberg fossil from the middle Pennsylvanian in Upper Silesia, Poland. I suspect that it is of the trunk and the nice, very fine striations are clearly evident in the close up (Photo2). Photos 3and 4 are of cordaites leaf specimens from the Mazon Creek area that was identified by both helpful Forum members and me. The close up of the Mazon Creek specimen (photo 4) clearly agrees with the literature in that they are strap like leaves, they do not have a prominent central vein and they do have equal, equally spaced veins. The Mazon Creek leaves also appear to be on a branch and sigillarius leaves apparently do not. Photos 5 and 6 are of a fossil from SW Pennsylvania that I have identified as a cordaites fossil. As with the Mazon Creek specimen, it is strap like, it has no prominent central vein and the veins are equal and equally spaced. The quality of the close up in Photo 6 is not the best and you might have better luck enlarging Photo 5.

  3. Plant impressions i found in material from the Coleraine formation of Northern Minnesota, which dates to 100-90mya, i confirmed with a paleontologist that these are first known plant impressions ever found up here which has me excited but neither of us know anymore than that theyre plant impressions, can anyone here maybe give more specific information from my pictures? i hope these pictures are good enough, i donated it for further study so I can’t get more. Even if you can’t ID them i still want to know what you guys think!

    Baffled

    This one had a complicated life. It appears to be metamorphic with quartz veins. Wrapped around it are leaves that resemble cat tail leaves or some sort of water plant. . I first thought they were dried or baked on the core rock. No these Leaves are not being scraped off the core rock. They are rock. Limestone leaves that appear to wrap around a core metamorphic rock that somehow fell into perhap a bog or marsh. Was it buried in a peat or some sort of bog ? I’m just baffled. The area where it was found is Watts Bar Lake near Nashville Tennessee. That corner of the lake was at one time dynamited. So it is not like adjacent rock walls. There was more than one. I was sure I could scrape the leaves off but they have become rock. Looking forward to your thoughts on this.
  6. A few days ago we visited Penrose State Forest (south of Sydney, Australia) to look for fossilised leaves. There are a few specimens from this locality in the Australian Museum collection and one of our contacts tracked down the sites many years ago. I'm not sure which species are represented here, there are a few similar described Tertiary sites like this one in Australia but this one hasn't been studied to my understanding. I doubt these can be reliably identified given the poor quality of preservation but they're still really pretty imo, the matrix is gorgeous. Here is the first specimen, I'll post some others as I photograph them
  7. Hello all!! I am a graduate student at Oregon State University, a geologist by trade, but a paleobotanist on the side (see my publication :https://www.journals.uchicago.edu/doi/abs/10.1086/721261?journalCode=ijps). I am going to add to my Paleocene fossil plant collections, and am going to make a tour all around eastern Oregon. I will of course visit Fossil (again) for some more Bridge Creek Flora specimens, but do not personally know the area super well. Do any of you have any recommendations for plant fossil locations where I can legally collect? It would mean the world to me, I am trying to make my collection more robust, and hopefully produce some scientific literature from them. I would be open to non-plant fossils as well. I know the Mitchell area has some plants, (Bridge Creek also) and will be in that area, but if any of you have specific spots anywhere in eastern Oregon, I would be much obliged. I understand the sensitivity behind disclosing locations, so if you dont feel comfortable, want to keep things secret, maybe just drop me a hint, I am a geologist, and if put in the right area, will be able to find fossils on my own, I just need some help, eastern Oregon is SUPER big!!!! Thank you!!! -Nathaniel Edmonds

    Plant fossils I hope

    Collected in Woodbine which seems to be popular lately, never was quite sure what to look for and hope this is it, gotta be leaves right? Not sure what the cylindrical might be.

    Round 3 of Western Trip

    The third chapter about my trip out west has been a bit delayed in coming. @piranha graciously referred me to a book on Green River leaves, the main subject of this posting. It was a wonderful book full of beautiful pictures and relevant information on the flora of the Green River Formation. And I immersed myself in it as a way to“semi ID” my finds. For those who are interested: MacGinitieH.D.1969 The Eocene Green River Flora of Northwestern Colorado and Northeastern Utah. University of California Publications in Geological Sciences, 83:1-140 In addition to piranha, I need to thank a “to remain nameless” forum member who directed me to the site. I also stopped at Florissant for a short time, which contains many similar if not identical species at its location. So, my finds are a mixture of the two sites, but mostly Green River. To begin my journey, I exited the highway onto what was thought to be the proper road. It seemed more like an abandon trail, but the landmark mentioned was present. It concerned me, with the small low riding rental car being driven, the likelihood of getting stuck existed. Roads like this never stopped me before, so off I went. And besides, it is a rental car!!!! Looking at my directions, it instructed me to turn right at the next “dinosaur”. What a unique instruction. I couldn’t wait to see what was ahead. After seemingly hours, traveling under 10 mph, seeing nothing but expanses of sagebrush reaching to the horizon, I finally reached my next turnoff. And yes there it was, the dinosaur, clear as day (mixed in with a little pareidolia) soaking up the warmth of the morning sun. After turning right and many more rough miles of travel, I finally reached this isolated spot of Green River Formation. It is the light-colored rock in the foreground. The beauty of the Utah landscape overwhelmed my senses and I just sat on the rim of the canyon taking it all in. It is moments like this that keep me “fossil hunting”. My mind, body and spirit were united as one! Enough of this meditation stuff. You want to see fossils!! First up are the possible insects found. Again, pareidolia may be part of what I am seeing so forgive me if some are misidentified as insects. My readings told of seeds frequently encountered in the Green River. These pictures depict what I believe are seed like structures. Possibly Somara ailanthus: A legume pod?? Next are unknowns to me. They appear to be coniferous. The next specimen was tentatively IDed as a coniferous leafy shoot. But in the book that I attempted to make my IDs from, the tip of a fern, Asplenium delicatula looked very similar. Woody pieces are found on occasion. The first one pictured matches Equisetum winchesteri closely. The next two are unknowns that I keep seeing as flowers. Hopefully not more pareidolia. An odd trace fossil. Now I will show samples of the Green River leaves found. I was unprepared for splitting this matrix. My lowly bon big face Estwing brick hammer could not peel up large enough slabs of matrix, resulting in many partial leaves like these. Be prepared for the need of multiple small chisels and pry bars if better specimens are wanted. The first leaf is similar to Quercus petros. The next leaf is suggestive of a legume. Finally Eugenia americana?? Next are a few Florissant leaves. The middle one possibly Populus heeri. Next up is Astronium truncatum. Notice the matrix is NOT flat and the leaf conforms to the undulations. This is common with leaves from Florissant. Dinner time!! I will finish this post when my after dinner nap concludes!

    Crinoid? How is this possible?

    Hi all! First post. I found these in my backyard, different spots, months apart, near Keller, TX. I've hesitated to post because I feel like this can't be possible and I must be missing something obvious as a novice fossil hunter. The rock in first 3 images was found 2/3 buried, including the part with the... leaves? It was getting dark, so I thought a leaf had stuck to it somehow. I tried scraping it against something to knock it off... then tried to pull it. When it didn't budge, I decided I'd deal with it inside. First pic is front after it had dried and had some dirt brushed off about a week later. Second is the back side, dried out. Third is front, just after bringing it inside. (Edited to correct descriptions. I somehow uploaded in reverse) The other one, in last 2 pics, was also found partially buried in my backyard, but many months ago and I can't remember specifics of depth. I'm always digging something up lol. Any ideas?
  12. Found this today, which I think is a fossil of leaves? Thanks! Location: Monterey Formation shale, Monterey County, California (Miocene) Outside of Carmel Valley, near Garland Ranch, among pea crabs (Pinnixa sp.) Description: About an inch and a half in length (I could get exact measurements). It looks like they have a complete margin(?) with a central midrib and veins that alternate. From a single split, so, positive and negative sides.

    Chuckanut Formation leaves

    Hey gang. I'm hoping to get IDs for a couple plant fossils I brought home from a recent trip to the Eocene Chuckanut Formation. Thanks for the help.
  14. Currently away from home on a work trip but that has allowed me to explore the silt stone laid down by Lake Manuherikia in the Otago region of New Zealand. The period is early to mid Miocene (16-19 million years). I have spent the last couple of evenings searching sites for fossil leaves or anything else I can find. FYI the bottle cap is for scale. I have nothing else with me but I figure most bottle caps are the same the world over. The above is part of a large palm frond. Hyridella shells above in matrix. Below are an assortment of the other leaf fossils I collected. Hopefully I get to go out for a bit more fossicking before I head home at the end of the week.
  15. I've always wanted to visit the Florissant Fossil Quarry due to my interest in paleoentomology but for one reason or other, I was never able to make it out there. I was finally able to make a detour out during a roadtrip returning from a funeral last week. There were beautiful calm skies, which was lucky too since heavy rains were forecasted for the next 2 days. After a good 5 hours, this is what I had to show for my efforts: Most pieces will have unidentifiable organic smudges. Aside from that, small leaves are the most common readily recognizable fossils. I am a terrible botanist, if anyone has any IDs, that would be awesome.
  16. Location: Missouri Time period: Pennsylvanian Formation: Possibly Upper Winterset Limestone Hello! I happened to come across one odd fossil that I could not recognize Some close ups on the leaves The only thing I could certainly determine it is some sort of Fern but beyond that I am unfamiliar of what species it could belong to My next specimen is a Fern leaf of some sort but due to its poor preservation is hard for me to determine what it is from, any Ideas?

    Florissant leaves

    Hello everyone, sorry to be posting so much Florissant fossil quarry material, but I'm going through my collection of foliage and still need these ID'd. Most of these leaves are obviously pretty common, but I can't find some of them in the book Fossils of Florissant. So here they are: 1. Think it's a Fagopsis, but just double checking. 2. Don't really know, feeding traces around the edges.
  18. Throwing Shade When you look at beautiful fossil leaves, have you ever wondered what the forest was like? Was the leaf from a tall tree, hogging the sun at the top of the forest? Or did it grow in the understory, in the shadows of big trees above? Perhaps we can figure that out. Please join our next online meeting of the DPS at 7pm on Wednesday, October 14th, when we will hear how to “see the forest from the leaves”. Joe Milligan, PhD candidate at Baylor University, will speak on "Sycamores shine a light on ancient canopy structure”. Joe has a BS in Environmental Science from the University of Maryland Baltimore County, and an MA in Earth and Environmental Science from Wesleyan University. He is doing several research projects for his doctorate, including estimating the CO2 content of the ancient atmosphere from fossil leaves, which is supported by a scholarship from the DPS. In this work he studied living trees which were grown in different shade conditions, and determined how the leave shape, microstructure, and even the carbon isotope composition are effected. Sycamores are one of our most beautiful trees, and distinctive fossils, so it will be fun to learn how they might tell us about the structure of ancient forests. Wednesday, October 14th, will also be National Fossil Day! We will celebrate with two short talks on fossils that can be seen in our national parks. Tom Dill will give a short walking tour of giant spiral beaver burrows along the Daemonelix Trail in Agate Fossil Beds in Nebraska, and Estée Easley will talk about Florissant Fossil Beds in Colorado, and their virtual displays and online activities. So stay online after the main presentation to see more fossils. Please join our Zoom meeting by clicking on this link: https://zoom.us/j/92213920218?pwd=N0l4eXhtQW9lOU1uQVp5OGh3OUFWdz09 Or start the Zoom app and join the Meeting ID: 922 1392 0218, with the Passcode: 466780.

    PALAEOBOTANY HELP

    Hi all I was wondering if anyone knew of any good sources- online or otherwise- for pictures (HD would be amazing) of plant fossils in various forms of preservation i.e. compression, cast/mould, permineralisation etc. Any help much appreciated!
  20. I'm going to be taking a drive this year from Pittsburgh to Charlottesville to SE Kentucky, to Knoxville, TN to catch some of the autumn foliage, and was wondering if anyone had any suggestion on fossilized foliage outcrops or spoils piles. I'm trying to focus on ferns and other plants, as I've collected a lot of marine fossils previously and want to get some new types of specimens. I've seen some stuff online about Ambridge, PA and Big Hill in KY, but haven't been able to find too many other public spots besides that. Just wondering if anyone had any suggestions or recommendations. Thanks.

    Belated 2019 Road Trip Fossils

    Last year, to celebrate finishing my undergraduate degree, my girlfriend and I went on a long (9,000+ mile) road trip around the western US and at long last (a little over a year since their discovery) the last of the fossils we found are out of the refrigerator and I’ve finally gotten all of them photographed. Here are some of the highlights and best fossils we found. A rough map of the route of the trip While the trip wasn’t entirely fossil centric we wanted to hunt at a few cool spots along the way. We chose to visit 5 fossil locations, the first of which was Clarkia Fossil Bowl in Idaho, a fantastic location for Miocene age leaves (Langhian Stage, ~15Mya) tucked behind a motocross track. These poor fossils have been through it all in the year between when they were found and when I finally got them dry. They’ve been soaked several times, gone mouldy twice, frozen at least once and flown across the Atlantic Ocean, all before spending the last 8 months in the refrigerator. Amazingly all but two of them survived perfectly including one of my favourite finds, a tiny flower. A maple leaf (genus Acer) still partly covered in matrix but with the stem intact. At some point I hope to get this one prepared. The best leaf find of the trip, with beautiful red coloration and mottling from fungus. A partial leaf, with beautiful vein preservation. The next spot was the American Fossil quarry in Kemmerer Wyoming to look for Eocene fish (Green River Formation, Ypresian Stage, ~53-48Mya). Splitting though the material left out by the quarry we found a few fish, primarily Knightia and Diplomystus. The best Knightia, including the best fish of the day with its head still partly covered. Some of the Diplomystus. The first needs some repair as it broke through the tail. The second has a counterpart as well and I’m hoping to frame it soon. And a mystery fish, I don’t know what species this is, it could just be Knightia or Diplomystus but it doesn’t look like the others we found. The star find came close to the end of the time at the quarry, a section of a puddle layer packed full of Knightia, at least a dozen fish piled on top of each other. The quarry manager was kind enough to let me take the blocks without splitting them thinner since the material is full of fractures and likely would not have survived. The layer as it split in the quarry (US size 13 hiking boot acting as a rough scale). The three pieces I managed to recover. The blocks are currently in a storage unit in Washington until I can figure out how to get them prepared. I am hoping the first two pieces can be reunited and the part and counterpart can be mounted side by side but I’m unsure about how to accomplish this. If anyone who prepares Green River fish has any ideas please let me know. The third locality we visited was Westgard pass in Inyo California, hunting for Cambrian archaeocyathids (Poleta Formation, Cambrian Stage 3, ~ 520Mya). We were only there a short time as there was a lot of driving to do that day, but I still managed to find one example in cross section. My girlfriend was more lucky, finding four examples. These are our favourites, particularly the third, which exhibits some dimensionality in addition to the cross-section. I’m absolutely thrilled to find anything Cambrian, and to make things even better the fossil locality is just down the road from the Ancient Bristlecone Pine Forest, home to living trees more than 4,000 years old and one of my favourite spots on the whole trip. We also visited Capitola Beach to search for rolled cetacean bone. I found two examples with one clearly showing the cancellous internal bone texture. To cap off the trip I wanted to do a fossil hunt in my home state of Washington. Since I still don’t know where to go to look for the elusive Pulalius crab, we decided to search the West Twin River site for shrimp concretions (Pysht Fomration, Oligocene, ~22-33Mya). We found over a dozen of these containing partial shrimp. I think they are all Callianopsis clallamensis since this is a common species at this locality. The first concretion that I found after identifying the right material. Another shrimp nodule containing a large section of claw. The head of a shrimp. Two non-crustaceans, a gastropod internal mould and a beautiful white bivalve in a small concretion. A mystery concretion with something eroding out from both ends. And last, one of the strangest concretions I have ever seen. The outside is hardened but the inside is a soft clay consistency with several bits of shrimp shell, completely the opposite of the hard in the middle concretions I’m used to. In all, it was a fantastic trip. I would love to go back to all the sites we visited, and there is so much more to explore next time I’m stateside. I’m looking forward to getting out hunting again. Stay tuned for the next big trip to celebrate finishing our masters. Benton

    Paleocene Plants

    I have tried without confidence on my IDs for these finds from Sweetwater County, Wyoming. I suspect Sycamore?? It would be great to get these labeled properly!!!! 1. 2. 3. 4. 5.
