  1. Last week I got the opportunity to go fossil hunting in an abandoned Lower Carboniferous/Mississippian marine limestone quarry near my home in Fife, Scotland. The quarry exploited a bed known as the Charlsetown Main Limestone. It is from this bed and the overlying beds of shale that I have collected the majority of my Lower Carboniferous marine shark and cartilaginous fish fossils from various sites across the Midland Valley of Scotland. I try to check the site as regularly as I can as new material is constantly being washed out of the spoil heaps, but the overall area where fossils can be collected is very small. I hadn't found anything worth keeping on the last few trips but on this occasion I found a nice near complete Cladodus mirabilis tooth on the first block of limestone I picked up, needless to say I was pretty chuffed! This tooth was found on the bank of a flooded section where the lapping water is eroding the side of a spoil heap and in the past Ive found two partial Cladodus striatus teeth here as well as lots of well preserved inverts like crinoids and brachiopods. Ive decided next time I go to take equipment for sieving the mud on the bank and bed of the pool for fossils, so hopefully by using this method I'll soon have lots more nice finds from this site to show! The flooded section with the Charlestown Main Limestone and shale layers above exposed (photo taken last summer):
  2. Here are a couple of small nodules that I photographed last weekend.Even after observing the photos I’m still stumped.They were found near Terre Haute Indiana.They were collected from the Busseron Sandstone Member of the Shelburn Formation, in shales above the coal seams of the Dugger Formation and are dated from the Middle Pennsylvanian, which correlates with the Westphalian D. The first one looks a little sphenophyllumish. The second may be an isolated sporangium from a cone bract,a seed or maybe just a pyrite deposit Just thought I’d let the collective brain of the Fossil Forum have a look.Any thoughts would be appreciated.

  5. Hi. I found this in West Yorkshire, UK in the Pennine Lower Coal Measures formation (upper Carboniferous). It is in a Marine concretion. It contains what I think is a Phyllocarid but when I was looking at it today I noticed a Tully monster shape. I'm 99% sure it's just a fracture in the rock rather than anything interesting but I decided to post some pictures here just to be sure. Thanks, Daniel
  6. Hi. I found this in South Yorkshire, UK in the Pennine Middle Coal Measures formation (upper Carboniferous.) Is it part of an insect wing or just a plant? I think it may be the negative half of the fossil though I'm not sure. Thanks, Daniel
  7. Hi. Does anyone have any Mazon creek fossils to trade? I'm mainly interested in non plant fossils. I have many different fossils to trade. If you have anything to trade please let me know what you would like and I'll let you know if I have any of them to trade. Thanks, Daniel
  8. Hi everybody. Recently I found this fossil in the coal measures, but I don't know what is It. Maybe seeds? What do you think? Regards Juan
  9. This my latest attempt at the newest version of a Tully. Cast in urethane plastic and airbrushed in acrylic paint.
  10. I found my largest fossil yet yesterday. I assumed that it was Lepidodendron and was curious what species it may be, but it occurred to me after looking through images that I may have some other form of Lepidodendrales. Can anyone confirm? It's about 29cm (about 11.5") long with a circumference of 53.6cm (about 1' 9"). Leaf scars are about 3.5cm (about 1.4") tall by 1cm (about 0.4") wide. The scars wrap around the nearly-cylindrical specimen, only absent on roughly a third of the backside (last photo) where it may have broken off or is still hidden under the matrix. It was found in the Hyden Formation (Middle Pennsylvanian) in Johnson County KY. The closest result I've found has been Lepidodendron lanceolatum, but the pits are more centered than those in my specimen and I haven't been able to find any info on whether or not they occur in my area. Rockwood suggested that it may actually be Lepidophloios that has rolled-up at a 90 degree angle rather than being a Lepidodendron cast, which would be consistent with pit placement. What are your thoughts?

  12. Hello everyone, I've some questions about this Pecopteris fossil (pic 1) from the Carboniferous of France. On the other side (pic 2) there are other leafs. Can you help me identifying them ? Thank you
  13. Hi all, This is my first post I found this fossil which i think is a crinoid segment from Carboniferous shale, in NW Ireland. It doesn't have radiating crenulate (if that is the correct term) but has parallel sutures? Best seen in right portion of fossil, which go down in the fossil at an angle. Fossil is approx 2cm in length. Any help would be great! Thanks
  14. Hi. I found this in South Yorkshire, UK in the Pennine Middle Coal Measures formation (Upper Carboniferous.) Is it a Coprolite? Thanks, Daniel
  15. Ive never posted a trip report before so thought it was about time I gave it a go! I took a trip to my favorite shark tooth site this afternoon in search of some Upper Carboniferous/Pennsylvanian shark teeth from the Westphalian A of the British Coal Measures. The site is a stretch of shoreline beneath the spoil heaps of two long closed collieries which dumped their waste material directly onto the foreshore. Blocks of the best matrix for vertebrate remains are hard to find and getting rarer, the majority of the beach boulders are basalt, sandstone and un-fossiliferous shales and mudstones. When you do find the right matrix its crammed full of fish scales, bones, spines teeth, coprolites etc but shark teeth can be hard to find. Today I came across a grand total of two small blocks of the right matrix along the entire stretch of the beach but luckily both of these contained a shark (well Holocephalian more closely related to the Chimaeras) crusher tooth! They need a lot of prep which I'll hopefully get done over the next couple of days. A shot of the the site looking rather bleak in the Scottish winter today:

  19. I was recently asked by Forum member Carl who works at the American Museum of Natural History if I would be interested in trading some Carboniferous shark teeth I have collected in Scotland which he would put straight into the fish collections at the museum. (For which he would trade for Mesozoic and Cenozoic teeth from the US). I was delighted at the opportunity and was just going to donate some specimens to the museum but Carl has sent me some beautiful teeth from his personal collection in return for them, thanks again Carl! The teeth I donated are all from a freshwater deposit of Westphalian A age of the British Coal measures and were collected from the spoil heaps of two long closed collieries in the county of Fife. I will post photos of the rest of them in the donations gallery but here's a couple of the more interesting specimens: Ageleodus pectinatus. (labial view)

  22. Hello all! Its been awhile since I posted on The Fossil Forum. Here are some specimens found at a local active mine. Lyginopteris or Pecopteris Fern with Lepidophylloides. Lepidophylloide whorls. Lepidodendron stem with Lepidophylloides and fern fronds. Notice near the bottom, several Lepidophylloides overlap forming a star. 3D Stigmaria cast. Stigmaria with rootlets...the first find small enough to hold in my hand. Most I'd seen were on larger stone...too heavy to carry or move! Calamite stem cast attached to matrix mixed in with fern and Lepidophylloides. Lepidostrobus (cones) Fern Rachis with fern leaves. Lepidodendron stem with Lepidophylloides and fern leaves. Sigillaria bark impression? Lepidophylloide whorls.
  23. Hello again! Here are some ichno fossils found last month. The coolest thing about finding these type fossils is most can be held in the palm of your hand. Mostly found in singles because the stone are in sheets, when they hit the ground it shatters into smaller fragments. The bigger slabs can contain one or more traces. Arthropod resting trace I'm guessing this is part of a burrow-tube? Diplichnites Not sure what this is, dunno if it is a big tetrapod or arthropod?? Multiple resting traces? Overlapping resting trace Diplichnites near the top and near the bottom a resting trace Protichnites This one is quite appears an arthropod of some type got struggled through the mud, found a dry spot and hopped away? Protovirgularia I rarely find any flora at this some that I have found. I was told this was a Cordaites Principalis? 3D Calamite Stem Cast Calamite Stem Cast A large Limulid resting trace with a diplichnites running thru the middle of it
