    Permian Wellington fm Teeth

    Hey all. I recently got back from a trip to the Wellington formation in Oklahoma, and I ended up with approximately 40 teeth. (Most of which were Xenacanthus teeth) I ended up with quite a few bits and pieces I couldn’t identify. To avoid overly cluttering one thread, I will post others later. These three are shown next to cm measurement, and are from the Wellington formation near Waurika Oklahoma. I will provide more photos as needed, it has been overcast and dark so the lighting has been more difficult. Thank you for your time!

    A Fossil A Day.....

    A Fossil A Day....keeps the blues away! Or something like that... I started an Instragram account (jamielynnfossilquest) and am posting a fossil a day, so I figured I should do that on here, to REAL fossil enthusiasts! I'm a few days behind, so I will start out with a few more than one a day but then it will settle down to One Fossil (but I will admit, I'll probably miss a few days, but I'll double up or whatever.) I'll start with Texas Pennsylvanian era, but will branch out to other locations and time periods, so expect a little of everything! So enjoy A Fossil A Day! Texas Pennsylvanian Fossils: Nautiloid Agathiceras ciscoense Brachiopod Neochonetes acanthophorus Trilobite Ditomopyge sp. Gastropod Straparollus sp. Bivalve Astartella vera Cephalopod Brachycycloceras sp, Brachiopod Cleiothyridina orbicularis
  3. https://www.smithsonianmag.com/smart-news/a-300-million-year-old-fossil-discovered-in-utah-could-be-a-new-species-180979042/ Nicely preserved specimen. Almost complete.
  4. I had the pleasure of arranging a special fossil hunt to the Red Beds of Texas - a famous Permian site that was originally described by Copes in 1870's and later by Romer. It's an old quarry on private land that we were able to take a group of 10 to hunt on. And I was corrected by our guide that it was really not so much a "hunt" as a "collect" because the fossils were literally EVERYWHERE! You could sit in a 10 foot radius circle and be picking up vertebrate material all day long! We collected for about 5 hours and everyone came away with some fabulous fossils. Lots of amphibian skull pieces, sometimes with jaws and teeth sockets, vertebrae, lots of little toe bones, shark teeth and spines and much more. Most were small things, but occasionally you'd fine a nice big vert or piece of bone. Full Dimetrodon skeletons have been recovered from this site as well as amphibian Eryops and others. Here are some of my favorites from the "collection"! Dimetrodon toe bone: 3/8 inch Amphibian Eryops Toe bone: 1 inch Eryops ungal (toe bone) 1/2 inch Eryops jaw and tooth sockets - 1 inch Amphibian skull fragment (the biggest bit I found - 1 1/2 inches) Eryops Tooth: 1/4 inch Another jaw fragment - 1/2 inch An unknown tooth: 1/8 inch Orthocanthus shark tooth (Fresh water shark - there were HUNDREDS if not thousands of these teeth, but rarely do you find a complete one. Some were big, almost an inch, but this one was 1/4 inch) The blue color is amazing Some awesome little amphibian tooth plates, all around 1 inch This one has little teeth that look like hersheys kisses! smaller one - 1/2 inch my best vertebra (found about 4 but most were crunchy). 3/4 inch A lungfish tooth 1/2 inch Lots of other bits and pieces of bones and spines: This is a Dimetrodon sail spine fragment. Some of the others found even better bits. 1/2 inch Edaphosaurus spine spur (a different type of Dimetrodon). Size 1 inch I can't wait to go back out again - I hope to find a Dimetrodon claw (a couple of the group did). Next time!!
  5. Earlier this month I got the opportunity to return to one of my Permian fossil sites that I haven't visited since around April. The site is located in McClain County in central Oklahoma south of OKC. According to a geological map the majority of the area consists of the Wellington Formation, however the bottom of the exposed area is shown to be apart of the Stillwater Formation. According to scientific publications the only fossil producing layer is mentioned as belonging to the Wolfcamp (296.4 to 268 Ma) particularly the Gearyan strata. I've spent multiple trips earlier this year searching the layer mentioned as being the fossil producing layer but have only found plant impressions. Which I'll post some time in the future. Out of the entire outcrop though, I have only been able to find vertebrate remains in one particular spot. An area that appears to be below the known fossil producing layer. On this trip though, I only spent about 4 hours searching the site because I also had plans to visit family for dinner. Overall, I feel I had a pretty good half day trip. Below are some pictures of the vertebrate remains I surface collected on this trip. I must admit I haven't dedicated any real time to trying to identify the various species from the site yet and have only cleaned the material upon returning back home. But just looking through them while laying them out for pictures, there appears to be Eryops, Edaphosaurus, Diplocaulus, a small Captorhinid as well as an Xenacanthus shark. I've been collecting and cleaning the vertebrate remains from this particular site since March of this year but have focused the majority of my attention towards collecting, prepping and identifying fossils from a different site/formation here with in Oklahoma. All the following pictures are from my most recent fossil hunting trip. ⬆️ Overall view of the site. ⬆️ Quick separation of the bone fragments into various piles. ⬆️ Teeth, mostly Eryops megacephalus. ⬆️ Xenacanthus shark teeth. ⬆️ Jaw fragments, larger fragments appear to be Eryops megacephalus. ⬆️ Small jaw fragment with 2 or 3 teeth, possibly belonging to Diplocaulus. ⬆️ Large vertebrae fragments. ⬆️ Small sized vertebrae, the top row appear to be Diplocaulus. ⬆️ Edaphosaurus sail spine sections, a couple fragments might not be from an Edaphosaurus but were placed in the grouping during a quick sort of all the fragments. ⬆️ Various skull fragments, Eryops megacephalus, Diplocaulus and possibly Diadectes along the top row. Diadectes were one of the two species initially identified from the site along with a temnospondyl according to the research papers I read. I have had a difficult time finding clear close up images of the surface of a Diadectes skull. That is, at least from a legitimate scientifically described specimen that hasn't had the majority of the skull restored. ⬆️ These two pieces are the largest of the fragments that I suspect might belong to a Diadectes. ⬆️ Small limb bone fragments. ⬆️ Possible coprolites. ⬆️ Last but not least, concretions with bone fragments. At least one of the larger pieces has multiple vertebrae and portions of ribs. One small piece has what appears to be a section of jaw with 2 teeth still in place. One piece even has the exposed bases of a small Captorhinid jaw, showing atleast 3 rows of teeth. Interestingly, not all that far away in the next county over in Cleveland county near Norman there's a site that has produced the remains of Captorhinikos chozaensis and Captorhinikos parvus. Exactly what species this particular jaw fragment is from I have no idea. But I'm hoping when I do dedicate the time to identifying the species from this site, I will be able to find enough bone fragments from similar sized Captorhinid remains that I can get a general idea of what species inhabited the site. ⬇️ For these next pictures I used my loop and did the best I could at holding the specimen while also holding the loop still and then also holding my phone up to the loop and still managing to press the take a picture button on my phone. All while trying to hold still so the pictures did not come out blurry. The picture quality is poor but I hope in the future to invest in a digital microscope with a viewing screen. ⬆️ I suspect this might be the exterior of a jaw with two teeth still remaining in the jaw. The possible teeth are along the bottom of the fragmented red/white bone. ⬆️ Captorhinid fragment showing just the base of at least 3 rows of teeth. The broken teeth are the reddish and black donut shapes. ⬆️ This is the small concretion with the Captorhinid teeth. The teeth are located in the bottom goldish blurry blob. You can kinda make out one broken tooth in the top right corner of the goldish blur blob.

    A block of...?

    Location: n-e Italy. Probably Permian or Carboniferous. It's a fossil? Algae?
  7. Hello, Just purchased some Permian matrix bags from Richards Spur, OK and the Texas Red Beds. I have a few items I'm wondering if anyone can help me ID. I do have some guesses for a few of them. Using a dime for scale. Red Beds Going to guess Eryops skull fragment on this one. I think these might be fragments of Orthacanthus spines. Partial vert? This one is so small I really can't capture any distinct detail in the photo. Most small teeth fragments in this matrix were the broken tips of Orthacanthus teeth. However this is much rounder (although I can make out at least one edge), has no serration as far as I can tell, and under a very bright light I can see extremely fine vertical ridges (striae?) down the length of the tooth. It is also colored differently. Not hoping for much on this guy but my best guess would be some sort of amphibian. This one I'm fairly confident is an Archeria "jaw"; I understand they would have had some kind of palate plate to help grasp/swallow prey? More info on that would be awesome. It definitely matches what I've seen on Google. Richards Spur, OK Am very interested in this one in particular. Some kind of rooted tooth, it has this strange acorn shape to it. Not seen anything like it elsewhere. Thanks for having a look and my apologies for the poor photos; all I've got is a magnifying glass. I think I need to buy a book so I can try and identify this stuff on my own!

    Dimetrodon Tooth

    Identification: This tooth was found in processed microfossil matrix from Waurika, OK, USA. Reptile remains in general are very uncommon, so if you think you've found many pieces of Dimetrodon teeth, you're likely mistaking many Orthacanth shark cusps. Orthacanth shark enamel is smooth, and the serrations are quite prominent compared to those on Dimetrodon which are finer. Dimetrodon enamel is not smooth, as seen on this one. Dimetrodon crowns are also broader. Shark cusps broken at the foot of the crown also flare out, where reptile teeth do not. Were this crown complete, you would also notice a conical/round depression in the base. This is unlikely to be from another Sphenacodontid based on the locality, presence of serrations, and enamel ornamentation. https://www.nature.com/articles/ncomms4269 Notes: This tooth is a post-canine/posterior tooth, which is the tooth position one is more likely to find in micromatrix since they are smaller.

    Fossil Sites in Western PA?

    Greetings, I’ve recently gotten back into prospecting fossils and I’m looking for some suggestions on sites to visit in western Pennsylvania. I frequently visit Ambridge PA to find fern and Calamite fossils from the Mahoning fm and would like to find more. I also would like to find fossils of early Permian (tetrapods, plants, or invertebrates). I hear that Washington county (south of Pittsburgh) has some great spots and would like to know if it were true. I also would like to show some of my findings from Ambridge as well. Note: I’d like this to be suggested places not just western PA but West Virginia and eastern Ohio as well.

    A Physicist's Collection

    While my prime focus is essentially learning how to accurately describe Nature in the precise language of mathematics, I've always been intrigued by natural history - it's actually what started me on the path to physics. The sort of interrogation that paleontology practices provoked me to think and question even further, down to the fundamental science which makes it all work. Collecting fossils has brought a large amount of enjoyment to my life, and is often a welcome distraction from what can sometimes be straining work. The knowledge that I accumulate along the way is also part of the fun. Here is my collection, which will always be a work-in-progress. There's still many things I haven't photographed yet, but I feel comfortable saying this is the majority. I don't have many big things, but I'm certainly pleased with the many small things I have so far. Links to albums: Dinosaurs Sharks North Sulphur River Post Oak Creek Permian Aguja Formation Harding Sandstone Devonian Galveston Fossils Miscellaneous Highlights / Personal Favorites: The ones underlined are linked to their respective fossil page in the Fossil Forum Collections, which has more information and photos. Infant Tyrannosaurus rex posterior tooth If I could keep only one fossil, it would be this one. It's from my favorite animal that has ever lived, and being from a young'un is just so darn cool. A true crowning jewel in my eyes. Juvenile Tyrannosaurus rex maxillary tooth Again, you can't go wrong with T. rex. It doesn't have the best preservation but regardless, there's a lot more to love. Tylosaurus proriger tooth (self-found) Undoubtedly my favorite find to-date. Finding fossils yourself adds that extra value to its place in your collection. I'll remember the moment I first saw it for a long time. Triceratops prorsus tooth Triceratops is another one of my favorite dinosaurs, I think we all grew up playing with toys of T. rex and Triceratops. Unique circumstances also allow for me to say it's Triceratops and not Torosaurus with some confidence. It's not perfect, but still a significant part of the collection. Avisaurus archibaldi tooth A bird tooth? Doesn't get much cooler or more uncommon. Dimetrodon cf. limbatus tooth I've always been drawn to "icons of life," since those are the ones we remember from childhood. Dimetrodon is definitely an icon, and I'm glad to have found one of these uncommon treasures (in micromatrix - it was a very nice surprise). Cretoxyrhina mantelli tooth One of my favorite shark species, the "ginsu" had sleek-looking teeth, ate mosasaurs and dinosaurs, and was overall a formidable animal worthy of admiration. Cretodus crassidens tooth (self-found) Another one of my favorite sharks. It's not big or complete, but the preservation is so rare for the locality (POC) - the gloss on the enamel is as if it fell out of the shark's mouth yesterday. Saurornitholestes langstoni tooth I'm currently working on growing the dinosaur component of my collection, and this is my first Dromaeosaurid. Dromaeosaur tooth (Hell Creek Fm.) My most recent addition (as of Sept. 4, 2021), and it's my best dinosaur tooth for sure. Unfortunately it will be labeled as only a Dromaeosaurid tooth for now, but it still is just a great tooth from a cool family of dinosaurs. Shark Tooth Riker Display I've got one riker that I've tried to squeeze as many teeth into as possible. I need to get a couple more, probably; there's a lot of teeth that deserve a riker, but are just lying around. I'll try to update this thread semi-regularly as I make acquisitions in the future.

    Lungfish tooth

    From the album: Permian

    Ornamented lungfish bone/scales are fairly common, but their teeth seem to be comparatively rare. This one is ~ 3 mm in its longest dimension. ^Mottequin et al. (2015)
  12. ThePhysicist

    cf. Dimetrodon grandis

    From the album: Permian

    Now how can this crumb of a tooth be attributed to Dimetrodon?? First, it's serrated. It could be shark? The enamel is not smooth (not very visible in this image, a little at the bottom), so no (additionally, the serration shape is different from those of Orthacanth sharks). That narrows it down to serrated Synapsids. It turns out that very few animals at this time and location had "true" serrations, not just enamel serrations, but bumps in the dentine beneath the enamel. The enamel on this piece happens to still be clear, allowing one to see the globular dentine underneath! From Brink and Reisz (2014), I'd posit that D. grandis is a suitable candidate. I'm also not an expert, so I welcome contrarian arguments. I highly doubt it's Therapsid, as I haven't heard of any from the Waurika locality. D. grandis:

    Labyrinthodont tooth structure

    From the album: Permian

    A "lucky break" in a Labyrinthodont tooth (likely Temnospondyl amphibian) still embedded in matrix reveals the intricate labyrinth of plicidentine.

    Dimetrodon tooth

    From the album: Permian

    Dimetrodon sp. Wellington/Ryan Fm., Waurika, OK, USA Post-canine/posterior tooth This tooth is likely from D. limbatus, given the locality and presence of serrations: https://www.nature.com/articles/ncomms4269 The same paper also rules out other serrated Sphenacodonts by the enamel ornamentation. Its smaller size could indicate that it's from a juvenile. It differs from the comparatively abundant broken Orthacanth shark tooth cusps in the microfossil matrix (what most people are likely to confuse with): the enamel texture is not smooth, the crown is very broad (indicating it's likely a posterior, in addition to its size), it has fine serrations that differ in shape from the sharks', and the base doesn't flare out. Were this crown complete, you'd also notice a conical/rounded depression in the base. A beautiful tooth from one of our surprisingly close cousins.

    Hatchling Dimetrodon Claw?

    Hi y'all. Found this in some Permian micromatrix from Waurika, OK. There's no way I'm this lucky, but is this a very tiny Dimetrodon claw? I've tried to get access to this paper, but still waiting to see if the authors will send the text. I'm fairly confident it's at least sphenacodontid, based on pictures I've seen on the forum. It's about 3 mm in length. @dinodigger@jdp

    MORE FOOTPRINTS (from the Permian)

    So a few months ago I traveled to El Paso, in search of some trackways from dinos and Permian amphibians. My trackways collection has been lacking for the better part of my whole life so I decided to go get some. If you haven’t already seen them, I’ll include them here: Now how could I possibly get new footprints if I’m all the way in DC? Well, I was doing some cleaning with a toothbrush on this exact rock and to my amazement, I started seeing little footprints in the stone. Knowing that I didn’t see them before, I freaked out and almost had a heart attack. There are now 9 different sets of tracks on this one little plate! I’m in shock. Here’s some new pictures of the newly uncovered trackways!There are 5 additional tracks that I had no idea were there for over a month. I had this fossils for that period of time with no clue that there were more. Now that I think about it, there were probably a lot more back at the place where I chiseled them out. I didn’t look carefully enough, but I won’t make that same mistake next time. I hope you all enjoy these!
  17. Hello everyone, I recently got some fossils from Russia, some plant remains from Perm Krai where I grew up and a couple of Productid brachiopods from Sverdlovsk Oblast. They are from the Artinskian stage of the Permian period, one is around 2.5cm in width while the other even though incomplete is absolutely gigantic, the largest I have in my collection. I am not great at identifying Productid brachiopods and the Permian is probably the period I have least experience with within the Paleozoic so I have not been able to ID them myself. The large one looks similar to some Reticulatia sp. I've seen online but all of those are smaller so I don't know if that's accurate, the smaller one I have no idea. Thank you for any help, Misha
  18. Hello. From a recent trip to the Perm-Carboniferous petrified wood, we brought back some very interesting fragments; nothing like this has come across before. Usually we find fragments of wood (chips), without knots, without a pronounced structure - just highly silicified, indeterminate fragments. But while this trip from a small area (just a couple of square meters), we collected several interesting fragments. This is a solid piece of the trunk with knots located at the same level. 7 knots. Another similar fragment, but split lengthwise. There are only 3 knots left, but a cavity with smoky quartz crystals has opened. I want to identify these findings. Having looked at the photographs and drawings, which depict Araucaria, I saw that the branches of this tree are arranged in "layers", i.e. on the same level. Why did I take Araucaria as a basis - in some literature, local layers are called Araucarian. I would be glad to receive any information. By the way, I have a similar trunk with knots on the same level - but it is from the Paleogene; much better preserved, replaced by chalcedony, and has 5 knots.
  19. Wow is all I can say. I cannot believe what I have managed to find this week alone. I went to Texas for a vacation, and I’m coming out with some of my best fossils (in my opinion) I’ve found this year. I came here hoping to score some trace fossils of what once lived here, and score some, I did! Since there are two different time zones, and 4 different types of fossils found, I’ll split them up based on environment, and time. With marine fossils going first and tracks going second. Permian first, and Cretaceous second. I’ll do a picture of the whole haul and then we’ll get started. I also was able to capture some tracks that weren’t collectible so I collected them with my camera. Taking a fossil out of its place in a rock like that causes more damage than it does good, so all tracks were already eroded out and separated from anything scientific. Anyways, here’s the stuff: Permian Marine Fossils: Permian Footprint: while collecting today, I was hoping for a Permian footprint. Literally as I was about to leave, I found it! There was also another footprint attached to the rock but it fell off and scattered along the debris of similar colored rock. I wasn’t finding that anytime soon! But anyways, here it is. You can see a few sets of claw marks from the amphibian that once walked across it. I’m really happy I found this on a small rock and not one that I would have had to leave behind. cretaceous marine fossils: I also found a nice crab claw but it was so embedded into the rock that I just took a picture of it. Some things are better left to be appreciated by other people! cretaceous footprints: I found a bunch of footprints embedded into the rock, I of course didn’t attempt to take these out of their rightful place and I left them to be admired by others. I found one eroded out of the rock, and broken and incomplete, but it’s a footprint none the less. I’m pretty happy about all I found in general. It’s hard to see but the first two toes are there, and the only reason I’m confident this is a footprint is due to the fact that there were others around. All around a great trip and I still have more to find because I haven’t left yet!

    Developing Orthacanth shark tooth?

    From the album: Permian

    This may be a pathology, or a tooth in development?
  21. Can anyone confirm this temnospondyl amphibian is Sclerocephalus häuseri? Thanks in advance. Unprepared about 70 to 80% complete fossil from the Permian of Germany.

    Labyrinthodont tooth cross section

    From the album: Permian

    A serendipitous natural break in a labyrinthodont tooth nicely displays the enamel in-foldings which give this class of amphibians their name. ^https://aaronrhleblanc.wordpress.com/2019/04/23/dental-origami-the-elegant-shapes-of-folded-dentine/

    Permian microfossils

    From the album: Permian

    These are virtually all the microfossils I found in two small bags of medium-grain matrix from Waurika, OK. The matrix was very fossil rich. The vast majority of the fossils are Xenacanth/Orthacanth shark teeth. Fish material is next most common, then amphibian, and lastly, identifiable reptile material is very rare.
