  1. Last summer I posted a trip report about finding some Pennsylvanian black shale in a river bed in East Central Illinois http://www.thefossilforum.com/index.php?/topic/106753-628-illinois-black-shale-trip-w-listracanthus/. I was able to visit the site again once more in the fall last year when the river was running much lower and collect more and larger pieces of the finely bedded and fissile shale. Since then I have been slowly splitting and going through the rocks I brought home, and finding many interesting fish parts- that is definitely the dominant fauna presen

    Shark Teeth St Augustine Florida

    Ok I was lucky to find these shark teeth in St Augustine last week. But help with identification please. My guesses are Mako top left followed by Sand Tiger and lastly a small Great White? Or could that be an extinct Mako? Thanks for your help.
  3. Are Isurus praecursor and Macrorhizodus praecursor synonyms? I have conflicting accounts on this and would like clarification please. Thank you, Bellamy

  5. In the last couple of months my son and I have purchased some unprepped Lebanese fossil fishy's. There are four known species of guitarfish from the Lebanese provinces of Hakel and Hajula. Rhinobatos maronita is one of these; this species was fist described in 1866 by Pictet and Humbert. Some purty dang cool stuff but the guy we are buying from does not know how to wrap and send fossils over seas! Our last shipment came in many pieces! Not good. My son is working on him to make it right? Aside from that Im going to do what I can to fix things. First up is one side of what I think is
  6. Heres a fun thread for those to show off their widest and fattest looking megalodon teeth fossils in thier collections. I'll set the tone with the widest fat boy in my collection, I don't have digital calipers but it measure roughly 5.4 inches wide by 6.1 inches long. When I close my hand together it looks even more monstrous. Share yours and join the wide boyclub Got the idea while thinking about what the widest megalodon tooth ever found measures, if anyone does know do share in this thread!

    FLORIDA FOSSILS I HAVE FOUND SO FAR

    heres some photos of finds i have found at my local creek in pinellas county, FL decent finds for what was left behind, theres a lot to be explored over in the area and its a good site so im gonna work it for a while and see if anything important shows up
  8. Good evening to all participants! I have accumulated a lot of local (from Ukraine) material - I decided to sort it out, and recurring fossils, or not of interest to me, offers you an exchange. Everything in the photos is one lot. Consists of: 1. Tile from Carboniferous period with fern print; 2. A fragment of the armor of a armored fish Podolaspis Lerichei of the Devonian period; 3. Tile with Silrian brachiopods and tentaculites; 4. Mollusk of Neogene; 5. A small fragment of a fossilized araucaria of the Carboniferous period with quartzite crystals; 6. 2 fragments of orthocer

    Shark Tooth ID - Florida

    Please help ID any of these sharks teeth that were collected from the west coast of Florida (near Venice) this past weekend. Based on my research, the top two rows look like Sand Tiger and the bottom two look like Lemon. Would this be correct or are there any that look out of sorts?

    Shark Tooth ID - Florida (Part 2)

    Please help me ID these shark teeth that were found on the west coast of Florida (near Venice) over the past weekend. My belief is that the top row could be Great White and/or Megalodon (very nice serration on the largest/first one), the second row is either Bull or Dusky, and the third row is Hemipristis (Snaggletooth). As for the fourth row... the jury is still out. I am most intrigued by the third/tiny one (from left to right). It looks different from anything else I have ever found. Very compact, lots of detail, and oddly shaped. Any ideas???
  11. Hey all!!! Been a long time since I posted on the actual site. I'm doing Christmas in Bonita Springs, Florida this year and would love to do some shark tooth hunting. I'm not familiar with Florida fossils at all. SO! I'm starting my research and thought I would take in any recommendations to work around. let me know and I'll share!!! Thanks!
  12. Can anyone please help me in identifying this tooth? I’m leaning towards an extinct sub species of the great white however I cannot be sure.. any input would be greatly appreciated

    Shark Tooth Found

    I found this tooth at my normal overburden site, at work, it is the best shark tooth i have even found. Looking at Shark tooth I.D guides my guess is that this is a Auriculatus tooth. What do you all think?
  17. I am in NYC for 5 days at the beginning of March, and I intend on taking at least one of those days to go find some fossils somewhere. I have nerded out pretty hard and crossreferenced localities etc and I have basically narrowed it to Big Brook, Shark River, or trilobites. I would love opinions on where the collecting would be best between Shark River and Big Brook (I have a bunch of Miocene shark teeth from California but absolutely nothing from the Cretaceous). I have some trilobites from California (white mountains) but nothing particularly special. Any and all suggestions will be consider
  18. Receiving this gorgeous but mysterious specimen is from Upper Pennsylvanian limestone dated around 290-300 million years ago from somewhere around Kansas City. Looks like a tooth to me and my best guess would be orodus? But I have little experience with Pennsylvanian shark teeth in general and especially from this area, also cannot find a comparison elsewhere online. Any help will be appreciated.

    Cleaning a sharks tooth

    I wanted to show some photos of a tooth that cleaned up really well. This is a small tooth I found some time ago. Regardless of its size, the quality of the specimen was excellent. So I cleaned it and polished the enamel. I thought the difference was significant. My learning was that in some cases cleaning and polishing can greatly improve the looks of a specimen. Before the cleaning. Fresh out of the river After cleaning and polishing the enamel
  21. Help request! I am putting together a tool for judging rock age based on very crude, whole-rock, hand-sample observations of fossil faunas/floras -- the types of observations a child or beginner could successfully make. I view this as a complement to the very fine, species-level identifications commonly employed as index fossils for individual stages, biozones, etc. Attached is what I've got so far, but I can clearly use help with corals, mollusks, plants, vertebrates, ichnofossils, and the post-Paleozoic In the attached file, vibrant orange indicates times in earth history to com
  22. I found an old box of fossils I had when I was a kid. I dont remember where I got it from but I would appreciate it if someone can I.D the shark teeth from or or the brachiopod.
  23. I have some teeth from Cognac area to ID. Selachians found are Parvodus, Polyacrodus, Lissodus, Hybodus, Hybodontidae, Rhinobatidae but I don't know them. Is someone knows this fauna ? Here are 4 pics done with my phone, but perhaps I have to try with an APN... They are very very small. It is written "Portlandian" on the pics but the right stage is Berriasian. I think I have 2 different species in my collection, and I must do a lot of pics Thanks for you help. Coco
