  1. I'm not to sure if is the right part of the forum to be asking this but is anyone or would anyone know any experts/specialists that have a focus in Triassic Reptile/Amphibian Remains? Can even be a recomendation of an email address for a specific paleontologist I would be able to contact in regard to discussing a specimen directly and privately.
  2. Hi Everyone, I recently broke open a rock on my property and found this interesting fossil. I have tried to identify it but can’t find anything that looks similar. I know it's a long shot for an ID, but more knowledgeable thoughts on what it could be would be very much appreciated. It was found in Missouri, Jackson County, north of highway 350, south of highway I-70, east of 435, and west of 470. The rock was dug out when digging a basement and subsequently cracked apart and the fossil was within. Basement location is atop glaciated ridge. I am guessing (serious amateur here) that the rock would be somewhere in the Late Pennsylvanian Stage? The red circle in this map below is the approximate location it was found. (http://www.kgs.ku.edu/Publications/Bulletins/83/07_up.html) Here are the pictures… Thanks in advance for any info!
  3. Branchiosaur - Is the ID Correct?

    Hi all, Been eyeing up this item online. Advertised as species Apateon pedestris. I thought it would be best to ask for some opinions before dropping money. I think it looks pretty nice, and at a good price. I like that it doesn't have the preservative applied to mimic skin impressions (like the majority do) but I wonder if the ID is accurate (or if it's even legit.) I'd love to add more amphibian material to the collection and I think this might be a good choice. Thoughts?
  4. There was a piece of land sticking out between valleys of about 2000+ sq meters. I found there many various fossils. On that ridge sticking out, there was a rocky bed floor split in 2 or more & were cracked as an earthquake would do. Between them, I found this piece along with another, I posted earlier not far inside the crack. the 2 pieces I posted were not close to each other but rather in another crack near. this piece was deeper in the crack and it was broken as it fell back on my first try to pull it. The matrix below is woody and lightweight and can be broken. It is the same type of the previous post. On top, the frog-like trace is different than the rest is rock and very petrified. where the frog-like trace is, there is a thin layer that covered the whole part.
  5. A new discovery of a 375 million year old Tetrapod called Parmastega aelidae with some very unique features from the Komi Republic. http://www.sci-news.com/paleontology/devonian-tetrapod-parmastega-aelidae-07730.html Thought some of you might find this interesting.
  6. Greetings fellow fossil lovers! Below is an assortment of fossils from the Waurika clay from the Lower Permian that I'm having trouble placing an id on. Scale bar is in millimeters. Any help would be greatly appreciated. Thanks All! Jacob
  7. Fossilized Egg?

    I found this sometime in the 1970’s State: New York, County: Suffolk, Township: Brookhaven, Hamlet: Rocky Point on Broadway Beach on the shore of Long Island Sound. The fossil weighs about one ounce. The hole was there when found, through it there is hollow space, but I can also see that there is some structure or substance inside.
  8. Discosauriscus austriacus

    Classification Kingdom: Animalia Phylum: Chordata Order: Seymouriamorpha Family: Discosauriscidae Genus: discosauriscus Species: discosauriscus austriacus
  9. I just added this wonderful specimen to my collection. The species is discosauriscus. Little is known about the species other than the fact that they were predators based off of teeth. They may of had electrospective organs. On this slab running through the head of the specimen is a thick calcite seam from where the rock was faulted and shifted. This was found in the Czech Rebublic in the Limnic Deposits. This is the first fossil I've purchased all the others in my collection I have found.
  10. Hi folks, we bought a sample of microfossils originated from Waurika, Oklahoma. It was really fun to search through the little pile and try to ID the pieces. The result was a short video We decided to share it hoping for comments and more interesting info from the knowledgeable audience of this forum. What's really cool about microfossils is the amount of details and often stunning preservation of tiny pieces. Does anybody know a microfossil locality in Central California?
  11. Trimerorhachis skull?

    I found this in west Texas, in the Red Bed area. I was wondering if it could be an amphibian skull fossil of some kind. Maybe a trimerorhachis? I'm still learning about the extinct amphibians and reptiles in my state. Any suggestions are welcome!
  12. Carboniferous amphibian jaw?

    I found this in the Pennine Middle Coal Measures formation (upper Carboniferous) of West Yorkshire, UK, a while ago. At the same site, shark teeth were common, as well as Rhizodonts and other fish fossils. At first, I thought it was a fish jaw, but now I am unsure if it is indeed a fish jaw or an amphibian jaw. Does anyone know what this is? Thanks, Daniel
  13. Temnospondyl help

    Here's a hard one: This is a very nice temnospondyl skeleton (you can see the sclerotic rings!). It measures about 11cm long from snout to what is preserved of the tail. My question is: Can anyone tell me the genus/species and provenance of the fossil? I was told by the previous owner that it was possibly Platyrhinops from the Lower Triassic of Germany, but I have no idea. It looks like maybe a very well preserved Permian age Discosauriscus from the Czech Republic or some sort of temnospondyly from the Pfalz of Germany. I am happy to share more photos. Thanks for the help :-)

  16. Hello everyone. I am an incredibly novice fossil hunter from Pennsylvania. From where I live, it is heavy Carboniferous territory. One of the items on my bucket list is to eventually find something from a temnospondyl, even if it is nothing more than a trackway or even better - a bone fragment! Would anyone be willing to share with me advice on what to look for / or what has helped them in finding anything from a Temnospondyl or Lepospondyl? Do they appear more in certain rocks than others? I live in the Pittsburgh area, near where Fedexia was discovered ten years ago. I'm hoping to eventually find something related to Fedexia or another temnospondyli. From what I'm realizing, these little guys are hard to come by. Any advice? Thanks everyone!
  17. Lance fm Vertebra

    Hi all, wondering if you could help me on this vertebra's identity, I found it in Wyoming's lance formation this past summer. I think it might be amphibian but I'm not sure. It's about a quarter of an inch long.
  18. I have for trade miocene salamanders from Bosnia. The images are of lower quality, since they are also more accessible for exchange. I also have other specimens, better quality or natural untreated. My interest are megalodon ( Charcarodon) teeth, miocene fossils ( echinoids, crabs, big gastropod,bivalves) all kind of interesting specimens. Im also interesting for fossils which I could use for compare with european fossils. If you have something interesting please contact me.Thanks!
  19. Bridger fm. Amphibian

    Hello fossil friends. I have this skull piece here that's quite interesting. Looks to be some kind of amphibian skull. The locality is Bridger fm, but after doing some research I haven't been able to find any information on amphibians from this locality. Would anyone be able to shed some light on an ID for this piece?
  20. Trimerorhachis insignis

    Hi, I recently bought this online and it was listed as a Trimerorhachis Insignis tooth from Jefferson County, Oklahoma. After comparing it with other images I think this could be a claw and not a tooth, but I'm not 100% certain... Could anyone please confirm if it is? Thanks, Billly.
  21. Over the winter I was freezing and thawing nodules found in reclaimed coal mine spoils from the Pennsylvanian Shelburn Formation, Busseron Sandstone from Vigo County Indiana. These contain flora and rare fauna similar to the Braidwood Biota from Mazon Creek. This nodule split off a tiny bit on one end and I set aside for further investigation after a quick glance revealed an interesting pattern. Then I forgot about until I was recently unpacking from a move, and re-examined it under magnification. Unfortunately, the piece that split off the end was lost, so I only have the one side, but it shows a small rectangular patch of texture, about 10 mm wide. The piece preserved shows folds and wrinkles, as well as what looks like a tear in the center, and looking under magnification reveals the entire piece is covered with tiny pebbly bumps. My first assumption would be plant material, but it doesn't match the texture of any of the other plants I have found at this site. A much less likely option would be a patch of skin from some sort of animal or egg casing. I would like to get it under greater magnification and will try to find an expert to look at it, but I wanted to put the best pictures I was able to take here for y'all's thoughts. Thanks!
