  1. Carnivorous theropod claw

    Correct me if I'm wrong, but this is definitely not the end of a digit from a large carnivorous theropod. The only potentials from the Morrison formation where it was found, would be different species of ceratasaurs, allosaurs, and torvosaurus, right? and they, along with most carnivorous theropods have claws at the end of every digit, including the little foot&heel stubbies, don't they? wouldnt this have to be from something without claws? Or at least no claw on this?
  2. Permian Ryan formation

    Does anyone know what the Ryan formation is? Is it a terrestrial site, or aquatic? What vertebrates are found there?
  3. KT boundary micro glass

    From the album Invertebrates and plants(& misc.)

    Debris, including micro glass "beads" from melted earth ejected into the air, from the KT boundary burn layer. Garfield county, Montana, Hell Creek formation. Late cretaceous (duh) *i added "misc." to this album because this didn't fit anywhere, and I thought it was really cool and should definitely be included somewhere. **There could even be vaporized dinosaur material as part of the glass and melted debris included. There definitely was plenty of it, but I guess realistically, unless it became evenly spread into the atmosphere and airborne debris, this is too small an amount of ejecta, and by percentage such a minuscule amount of vaporized dino, so sadly there probably isn't any.
  4. Edestus teeth

    From the album Sharks and fish

    The shark relative is genus of eugenodontia holocephalid from the Carboniferous-Pennsylvanian age Anna shale formation, Carbondale group, found in different Illinois coal mines. I dont know(yet)which mine these were found in. This unidentified species is of the "vorax-serratus- crenulatus-heinrichi" or "E. heinrichi group", with the teeth being more of a standard triangular shape, as opposed to being thinner and pointed at a forward angle as in the "E. minor" group http://www.thefossilforum.com/applications/core/interface/file/attachment.php?id=501751
  5. Show Us Your Green River Fossils!

    Hey everyone! I recently started planning a trip out west for next summer and was thinking of going to the Green River formation. One of those "keep all you find" digs. Thought it would be cool to see some fossils from there that some of you may have found. Or even some you could have purchased. Thanks!
  6. Mini Mosasaur collection

    From the album Marine reptiles and mammals

    A little collection of assorted mosasaur fossils from 2 different places that I got when I first started collecting. 2 different types of vertebrae, one is mosasaur, and the other is a questionable claim of mosasaur, a corprolite that was claimed to be that of a mosasaur, a tooth, & 7 rib fragments. 2 ribs have predation marks, as well as the large vertebra. The large vert has a round tooth indent on the very center. The 2nd rib down has tooth scratches along the surfaces, & 3rd rib down has a round tooth indent in the center, which is probably what caused a strip across the middle to break off. There are 2 other tooth marks on that rib as well, forming a diagonal line from above left of the center indent, breaking off a piece along the top, to below right.
  7. Xiphactinus vertebrae

    From the album Sharks and fish

    Xiphactinus Audax vertebrae NorthEast texas Ozan Formation--Taylor shale upper cretaceous
  8. Needing an ID on this NSR Tooth

    I found this tooth down in the North Sulphur River, Texas. I need verification of the ID on this one. Any ideas? Thank you in advance!!
  9. Oregon Coast Fossil Bone(?) ID

    I found this recently at the base of the cliffs near the Beverly Beach area along the Oregon coast, which I understand is part of the Astoria Formation. My first thought was it was wood but the spongy inner layer indicates the possible endosteum and therefore bone (see left picture). In the pictures above, the cross section of the specimen is on the left and the negative impression is on the right. In the above picture, the specimen is resting in the negative impression above some carbonized wood remains. Any help help ID'ing would of course be appreciated. By the way, if this would be of interest to an academic, any contact info would also be appreciated. I have much more precise location information and didn't dig into the cliff where it came from for fear of destabilizing the cliff and having an amateur muck it up.

  12. Basilosauridae partial vertebrae

    From the album Marine reptiles and mammals

    Vertebrae damaged during or before fossilization, from a basilosauridae. Found in Albany, GA, in the Ocala limestone formation, an Eocene deposit laid down by the swannee current between about 34-56 mya. The exact species is possibly still up in the air, since it is been suggested that it is something other than the original ID. We're still looking into the possibilities. Found in Georgia, so that limits the possibilities, but still leaves open a number of basilosauridae, including some dorudontinae such as Zygorhiza. Zygorhiza, which is what it was originally supposed to be, is iffy since it hasn't officially ever been found in GA, but I don't think that means it hasn't, doesn't that just mean it hasn't been found by scientific authorities, or confirmed by such? it seems however, that the person who ID'd it as Zygorhiza was Professor Mark Uhen, who I guess is an authority on the subject, but as before, they're not supposed to be found in GA. Another possibility from a different authority on the subject has ID'd it as Cynthiacetus, which I personally would prefer, but sadly that doesn't have any impact in the matter:(
  13. Hi all, For my birthday (some days ago, the 16th) I got a fantastic fossil fish from my sister! Behold, a Dapalis macrurus from the location Céreste (France). It’s from the Rupelian stage of the Oligocene (30 my). Now I was just wondering if anyone knew which formation this fish comes from? I’d love to have that info! Best regards, Max
  14. attempting to identify

  15. Is this a diplodocid tooth form Lourinhã Formation ?
  16. Whats are the dinosaurs fossils found in Dockum Formation ?
  17. This rock has so many different formations, like it's been glued together. Can someone tell me how this can be melted in several places with such odd formation?
  18. What is it?

    Things that make you go, huh?? Lol this appears to have some bone fragments, but can't say for sure. Anybody ever see anything like this??
  19. Rock formation?

    I found this one in Kansas. I have no clue if it's just a odd rock formation or what. Thought I would share
  20. Help please

    Any idea what this is??
  21. About a month ago, I headed out on two fossil trips to the well-known St. Leon roadcut in Indiana. I was hunting in the Liberty formation (late Ordovician) with the sole goal of finding some nice trilobites (which I definitely achieved!). Along with multiple rare trilobites, I was able to find some excellent examples of other fossils. The spoils were totally awesome, and I am itching to go back. I hope you enjoy. Best for last.
  22. Hi TFF friends, how are you? I walked a little bit today to one of my favorite geological formation here in Japan called the Himenoura formation. The himenoura formation is a late cretaceous (santonian) marine formation. It is divided in three levesl called the lower formation, the middle formation and upper formation (really surprising I guess) and the formation is made of mud stone from the bottom to the upper part of it. Fossil hunter mainly search the lower formation because it is the richest part in fossils of this formation. The lower part is very rich in bivalves, ammonites and vertebrates fossils (sharks [13 species], sea turtles and bony fishes) . The middle formation is less rich in fossils but you can still find some inoceramus, bivalves, few ammonites and some shark tooth ( 2 species). the upper formation has no fossils. I was wondering why the upper formation do not contain fossils. What woud be the cause of this fossil rarefication? Does it mean that all life in this part of ocean gradually vanished or is there another explication? Did evolutionnists lack time when they burried fossils in this formation? Cheers, David
  23. Nautiloid

    Hello, I found this today in Austin Texas and was looking for help on a more definite ID. Ive never found a fully intact one, really good day. I was leaning towards paracymatoceras hilli. Thanks
  24. Which formation?

    Hi all, I have a question for you guys... But I wouldn't be too surprised if you don't know the answer. Well, as a few of you know, my local hunting spot is the Zandmotor, a beach extension in the south of The Hague. You can find some of my finds here: Well, I find many bivalves and gastropods here, that are from the Eemian stage of the Pleistocene (130'000 - 115'000 years ago). Those shells (like the other fossils found on the Zandmotor) are from pits in the North Sea. Those pits are very rich in fossils, and when boats come to bring the sand onto the beach, the fossils are taken along. So the shells here are the same as those found in Maasvlakte 2 or in Hoek van Holland (two other fossil hotspots similar to the Zandmotor), just like on any Zuid-Holland beach. And I was wondering, does anyone know what formation these shells are from? I know that here in the collections, putting in "Pleistocene sediments" is good enough, but I would like to know if this is really the formation they are in. Thanks in advance for your help! Best regards, Max
