  1. Pit spoil flora

    These are a few pieces from the British coal measures of Derbyshire UK , in all the coal measure spoils and opencasts i have looked for fossils in i have not found many examples of Pecopteris and this is a first for me from this spoil site, the detail on it is poor as the nodule was open and in a wet area. Asterophyllites Cheers John
  2. Pit spoil finds

    These came from the same spot in a old British coal measures spoil heap that i have been visiting , each time i go i dig lots of holes looking for sweet spots but often with little success.This time i was rewarded with these 2 finds. Flora .....Calamostachys sp. spore cone This bit of fauna is about 18mm long x 2mm wide possible Palaeocaris ? Crustacea . Cheers John
  3. Fossil plant or animal?

    Hello all. I haven't been active here for awhile, too much tragic events the past couple of months, unfortunately. Anyway, I have been helping my buddy out again, sorting through a huge collection of minerals and fossils that he purchased earlier this year. I went through a unopened box today and there were so many plant fossils, many are quite stunning! This piece I am not quite sure about. If it is plant the leaves were quite thick and dense. The gloss is wild looking, and I thought bone at first. Only about 1/4 of the fossils in this collection had labels on them and most had fallen off in the boxes and are all scrambled up. It's been a chore, but snarge fun regardless, as you can imagine. I need help on this one. Sorry some of the photos aren't focused well. I should have worn my glasses today! KP
  4. Hey Gang, Was going thru another box and found a small piece that I acquired awhile back that I dont have a name for and looking for some help....if anyone has any ideas...much appreciated... Did some preliminary review of some of the Eocene pubs but nothing screamed yep thats it... From a quarry near Fossil Lake, Kemmerer, Wyoming. Green River Formation. Got some interesting fish bits in the plate as well... @piranha Thanks! Regards, Chris
  5. Plant fossil?

    I was wondering if this might be a plant fossil, or is it an imposter? Found in Kosciusko County, Indiana. Silurian? Devonian?
  6. I spent a few hours fossil hunting on two separate trips on Forest Service land in Montana. The first trip was this past spring looking for Late Oligocene - Early Micoene flora about 90 minutes outside of Missoula. The second trip was during at stint over the summer at a fire lookout tower in the Flathead where I spent just a few hours one morning looking at Devonian and Mississippian marine layers. Besides the obvious, the trips were quite different. The spring trip was a drive to a road cut on a Forest Service road while the summer trip was a seven mile hike in. Additionally the medium is completely different; flakey, brittle shale compared with big, blocky limestone. You can keep non-vertebrate fossils as long as you don't plan to sell them. Prior to heading to an area, I look through publicly available research, lectures, field trips, etc. to find possible localities. I only found limited information on possible identification of the Late Oligocene - Early Micoene flora and most of if was unpublished graduate work from a nearby site with only some overlap on species. Please feel free to correct any id's or throw new ones out! I believe these are cercocarpus, a mahogany.
  7. Pennsylvanian Flora

    It was about a month ago that I attended a wedding in Ohio. There was a free afternoon for me to do a little exploring. So I took a short one hour road trip to Ambridge, Pa. I had no tools to use other than a carpenter's hammer that I borrowed. Had I been prepared to split shale with the proper equipment, my results would have been much better. Pennsylvanian, Dutch Creek Formation flora exists in the shale cliffs across the Ohio River from Ambridge, along Route 51( a 4 lane highway) as you cross the bridge. It is a very safe area to collect since barriers are in place to prevent rock slides onto the road. This keeps you separated from the heavy traffic on the road. Here are typical fossils found at this site.
  8. Herein I plan to post pics of my modest collection of Mazon Creek fossils, but first a question. I found this nice little map in a paper by LoBue (2010) of the general Mazon Creek area, showing the location of the numbered mines/pits. Could any of you who know the area and the fossils explain in a nutshell which areas produce the Essex Fauna and which produce the Braidwood Fauna (or flora - maybe I should say 'Biota')? I know Pit 11 is the main source of Essex fauna (Essexella etc.), but is it the only place Essex fauna occur, and those other pits produce only Braidwood biota? Are they relatively exclusive of one another or is there some crossover? I work best with maps, so if anyone can annotate the map to make things clearer, please do. Also I'd like to know where the county lines are on this map. In the following fossil pics, I have incomplete info as they all came from dealers, auctions and such, I've never been able to collect the site myself, so the info I receive is typically incomplete and sometimes wrong. If anyone could narrow down any of the location info for any of the fossils, I'd appreciate it, and please correct anything that is incorrect!
  9. Pit spoil finds

    Some spoil finds from a few outings into the British Coal measures of Derbyshire. Sphenophyllum Emarginatum Mariopteris more finds too follow.........
  10. Mazon Creek ID

    Last night I was looking through a bucket of concretions that I want to open and I found this piece on the bottom, it is the only piece I have and would have picked it up about 15 years ago. I washed it off and I am stumped by this one. I have sent pics to other FFM who known Mazon stuff, but no definitive ID. So, I thought that I would throw it out to the masses and see what you think. I cannot tell if it Flora or Fauna. The ridges on this thing are very pronounced. Here it is for your viewing pleasure.

  12. Carboniferous Nut?

    After hunting through some loose sediment a few days ago, I dug up something that looks very much like an acorn/nut at first glance. I come across lots of compressed plant material and the occasional 3D fossil, but this is a pretty unique one. The area is very close to a soft rock site of Duckmantian deposits from Carboniferous limestone in north Wales, UK. I can't find much to identify exactly what it might be....so over to you guys!
  13. Mazon Flora help

    I've had a few specimens in my collection that I have questions about and am seeking some clarification. #1 another view #2 #3
  14. Since @Jones1rocks has been posting Mazon Creek fossils for ID's, I thought that I would post two that have stumped me and I would appreciate any help. Both of these concretions look similar to me- the first one I only have a half and the second one I have both halves. Sometimes I think that they are flora and other times I think fauna- such as a shrimp, but I have no clue. I am really leaning towards fauna and I have never found any others that are similar. Here is the one with only 1 half- different views:
  15. I looked at the weather and my schedule and realized that today was really the only good day in a while to get out. It was very foggy until I drove into the valley area and then the sun came out at about 10:45 am when I pulled in. The water was really low and I think they are working on the dam again. Anyway, I walked for a bit splitting rocks and did not find much but plant hash and seafloor hash. I switched sides of the river by jumping on rocks ( the water was really low) and then found this really cool Eospermatopteris branch. I've never seen anything that large before and, no joke, I heard something in the air behind me and saw a Bald Eagle fly over me head right after I found it. Luckily, I was able to chip it out complete and take it home. It was a really nice day and I wandered around splitting rock but not finding anything else of note. I was also being pretty picky and only looking for identifiable new fossils. So there you have it. The first pic is in situ, next one at home in crappy light and lastly the area I was in
  16. Chuckanut Formation Fossil Flora

  17. Need an ID for Oligocene Angiosperm leaf

    Found in Wenatchee, Washington. Deltoid leaf with palmate venation and serrate margins.
  18. With it being a great sunny, 76 degree day, I figured that I would go outside and crack open some concretions from Pit 4. The concretions that I picked to open did not have the greatest shape to them and most were end pieces from what would have been larger concretions. I knew from the shape of these end pieces that they would contain some type of fern. This time around, I was at about an 80% success rate of cracking concretions that had a fossil. The one good thing with the concretions that were found at Pit 4, was that the majority of them contained fossils. I only see one keeper in this group, an Asterophyllies, it should clean up nice and I don't find them very often. Pecopteris Ferns Lycopod Leaves / Neuropteris Stems / Bark Asterophyllites
  19. Fossil flora to identify

    All my text disapeared when i posted... so in short: Lake deposit oligocene age South of france 3 cm Fruit , pine cone ?
  20. Petrified Wood?

    Found this big chunk of what I think is petrified wood in North Carolina blue ridge mountains. If it is petrified wood is there any way to identify the genus or species I was thinking about trying to enter it in the fossil of the month topic since I actually found it less than a month ago. Thoughts on what it is?
  21. Calamities Brand and Fern

  22. Today was another day of going through some Mazon Creek concretions, it reminds me of the days in the past when people would collect at a place they called Chowder Flats because of all the clams that were found. The concretions that I opened today were ones that I collected from an area across from Shadow Lakes- the whole area around there was Pit 4. I was surprised at the number of single or multiple clams that were in this bucket- there was also a couple nice pieces of flora / bark.
  23. What is this?

    Hi, is this a correct identification? Or is it Otozamites gramineus? Found at Runswick Bay.
  24. Mazon Creek Finds

    This is my first year hunting Mazon Creek and I've found some cool stuff so far. I'm starting this thread not only for myself but for others to show off their personal Mazon Creek finds that you're proud of. I will be continuously adding to this thread to show pictures and i may need help with IDs. We all love pictures, so don't be shy. Show us what you got! And someone please correct any mistaken IDs (that's how we learn) Edit: IDs added Pecopteris mazoniana-Pit 2 Alethopteris serli-Pit 2 Lobetelson partial Shrimp-Pit 11 Achistrum (Sea Cucumber)-Pit 11 Rhaphidiophorus hystrix (polychaete worm)-Pit 11 Achistrum (Sea Cucumber)-Pit 11 Achistrum (Sea Cucumber)-Pit 11 Achistrum (Sea Cucumber)-Pit 11 Essexella asherae-Pit 11 Essexella asherae-Pit 11 Essexella asherae-Pit 11
  25. Seed?

    From the album Carbondale, PA

    I found a whole plate of these, but somehow only the one example made it home. 13mm long Carbondale, PA Lewellyn Formation Pennsylvanian period 299-323 myo
