ID requested: lower permian vertebrate fauna from Texas red beds & Waurika
ziggycardon posted a topic in Fossil ID
Hi! I recently acquired a few new additions to my permian collection, but there are a few pieces of which I am not a 100 % whether they are ID'd correctly, simply because I am not yet knowlegdeable about the material. So I thought it might be a good idea to post the ones I am doubtfull about here, as I know there are a lot of people more knowlegdeable than me who probably could ID them. The first item is a small claw listed as "juvenile dimetrodon limbatus" from the Red Beds, Archer County, Texas, USA I was a bit doubtfull when they said "juvenile" dimetrodon claw, but I got it anyway because it's a very nice permian claw which was an okay price regardless the ID. The second item is a caudal vertebra that was listed as "Edaphosaurus" (from the Archer City Formation, Red Beds, Archer County, Texas, USA) which came as a set along with a piece of sail spine which without doubt belongs to Edaphosaurus. The last items were sold as a collection of "Eryops megacephalus" fossils from the Wellington garbar complex, Waurika, Okhlahoma. From left to right are a piece of skull plate, a toe bone, a piece of dermal armor and a tooth.- 5 replies

Authentication of Australian Crinoid Fossil (Jimbacrinus Bostocki)
Peter Stahlberg posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hello! I'm new to fossil collecting (as well as this forum) and have bought my first fossil today. Being completely inexperienced, I thought I'd try asking folks on this forum whether the fossil I bout is authentic. I am somewhat skeptical of this crinoid fossil's authenticity given how well the crinoids themselves seem to be preserved in the substrate. They almost look like they're made out of potting clay and are very crisp. Could anyone with experience give their input? This fossil was a significant investment so I'd like to at least know I got what I paid for! Thanks in advance.- 3 replies

My brother found this years ago in the flinthills region of Kansas. He lost it for years, and just re-discovered it in some storage. I know next to nothing about things like this. Can anyone give me an I'd, or any info I can pass on to him?

I'm back in the big city of Houston, Texas! Yikes! The traffic here can be suffocating! I am missing the small town of Seymour, Texas already! Just came back from a dig trip up there. I was working with the Whiteside Museum of Natural History, under the director Chris Flis. I am learning so much! Pretty incredible creatures that lived some 287 million years ago! I have made several trips to the red beds over the past six years volunteering with the Houston Museum of Natural Science, but none can compare to the trips I have made since the June 7th, 2014 opening of the Whiteside Museum. I have been going once a month for a week at a time, and it never seems long enough! I am officially a digging addict! In July we found an incredible site that is the size of a football field. We are finding Edaphosaurus, coprolites, and Xenacanthus shark spines galore. This last trip I stumbled across some bone weathering out of the side of a hill and found a new Eyrops site! Tons of teeth and a beautiful rib bone, and as of yesterday part of a skull! The bone is spectacular and I can't wait to see how it preps out. Hopefully the rest of this guy is there. I'll have to wait until next time to see...

Hello all. Please help me decide on my next acquisition. I have the opportunity to buy a Permian reptile. The seller has both a captorhinus and Labidosaurus. Both are free from the matrix and prepped on a limestone display base. Similar in size. Is one more rare than the other? Not too much info on these. They were obtained from OK. Thanks

Our last post left off just before the Permian so this is where the students will learn about the series extinction events known as The Great Dying. One of the really interesting points in shark evolution is the survival of sharks during this period. They survived by adapting to a vastly different climate and a much different aquatic world. This is when the Hydobonts really emerge and the age of the modern shark starts. The first species we cover are the xenacanthids. We originally placed the Eel Sharks in the Golden Age of Sharks section but I wanted to illustrate that some that while a few xenacanthid sharks survived the Permian extinction, they died off shortly after. They were apex predators in freshwater ecosystems until 266 mya. The adaptations we hit on are the forked teeth and eel like body. Despite being an apex predator and some initially surviving the Permian, they were unable to survive long term either due to being unable to adapt to long term changes in the aquatic environments they formally dominated or were out competed by animals better adapted or both. The Hybodonts first start appearing in the fossil record in the Carboniferous era and much of the diversity of the family was lost during Permian but Hybodonts would became the dominant shark of the Triassic and lasted until the Miocene. They were varied in form, size, and habitat. Hybodont sharks lived in freshwater environments and marine environments. They are known from fossil formations that are shallow and deep. They evolved to fill a variety of ecological niches. They had different kinds of teeth for different kinds of prey. We specifically touch on Hybodus obtusus, Lissodes minimus, and the tiny, fairly recently described Reticulodus synergus as those are the species we have. My son's early sketch of Reticulodus is super cool. Given that this is smallest shark we are discussing, the art work is the hook more than the micro fossil. This is the one spot in the shark program that is a little visually underwhelming from a fossil standpoint. We have only a few small items so it lacks the visual appeal of the weirdness of earlier sharks and the WOW effect of the giant sharks that follow. This is a very fixable issue for us. I found a source for Orthacanthus teeth and we are planning on picking up a nice dentition set to go with our partial spine. Carter drew his Orthacanthus in a position that will match the dentition and spine when we have the teeth. A weakness now will be a visual strength in a month or two. I would really love to pick up an Anstercanthus tooth and spine too. They seem to be out there on the market from time to time. We plan on grabbing a few more Lissodes teeth and Reticulodus teeth too. A number of small teeth can make a nice display. Here are the fossils we currently have for the presentation Pic 1 Orthacanthus texanus tooth and partial spine of an unidentified Orthacanthus. Both are from Oklahoma I believe. Pic 2 Hybodus obtusus tooth. A small tooth and one that needs some additional material. Pic 3 A picture of all the fossils for the presentation including Lissodes minimus and Reticulodus synergus. Yup the dots are cool shark teeth lol I actually love the tiny sharks and this will be one of my favorite spots in the presentation because we deliver these right before we get into the giant animals that follow.

Unfortunately I am still waiting to be called back to work. I have been trying to find things to do to occupy my time. Last week was tough due to brutally cold temps. Finally we have hit a warm spell as yesterday and today hit somewhere in the 50's. I tried fishing for a few hours, but the snow melt raised the water levels and made the creeks muddy. Atleast it was a beautiful day to be outdoors. When I got home I decided to finish looking through some Permian micro matrix from Waurika, Oklahoma. I got this from @Fossildude19 who got some from @Jeffrey P . While I did not find a lot of fossils in this batch, I did find a few teeth. I found one very small Orthacanthas tooth, which I was really hoping I would and a few which I am not sure about. Also last night I finished going through the last bit of matrix from Sharktooth Hill, which I got from @caldigger in an auction lot that I won. This matrix was extremely loaded with fossils. First up is a pic of the Permian teeth.

Hello helpful fossiliers, Help please. These fossils came from outside Moab close to the Colorado River, but on a high shelf. The river is not visible from this location. Roadside Geology of Utah identifies this area as Permian, as did a BLM paleontologist. They are from about 10-15 miles SW from Moab. The rocks are largely a red base (clay?) with a gray-er surface. These three pictures are actually 3 different locations on the rock, but I think (wonder if) they are the same life form. The first is about 2 mm long. The ruler shows a mm scale. You can see the cross section end of the item on the fossil closest to the ruler. The second is a round disc from elsewhere on the surface and the third is a connected series of round discs. My sense is that the disc and connect discs are crinoid segments. Is the first picture also a crinoid, or am I way off on all this? I can post additional pictures if anyone asks. Thanks. Tom

This particular species had spines attached to the shell which is not all that common. There are four spines attached on the thumbnail brachiopod. The holes in the shells were where spines used to be attached. Found during this trip here:

If anyone is familiar with Permian tracks, can anyone ID these? All I can tell is that they appear to be synapsid tracks, but not Dimetrodon. I'm assuming that means Edaphosaurus is out too, but that's all I can figure. the ONLY details still known are that they're Permian tracks from somewhere in Arizona. There's no more information available. There's 4 plates... 1-pic 1 2-pics 2,3,4 3-pics 5 4-pics 6,7

I found this in a creek, eastern edge Flint Hills, Greenwood County, Kansas. The creek is in and drains through the Early Permian. Formation is unknown. It must be tree bark and I'm guessing some kind of palm because of the leaf scar. It curves only slightly so I would also guess it's from a large tree. I took a file to bottom of leaf scar and there are only faint lines revealed. This appears to be a sandstone and has tiny sparkly bits in it.

Cephalopods, trilobite, other invertebrates, Permian reef slope (Guadalupe Mountains National Park)
verydeadthings posted a topic in Fossil ID
Hi guys! This is a continuation of a previous post focusing just on the sponges. These fossils are from the Capitan Formation, which is Permian Period, Guadalupian Epoch, Capitanian Stage. Because these fossils are in the park, no collecting was allowed, and I can't provide additional images. Any confirmations about the identification or suggestions about a more specific identification are welcome. This trilobite is the only fossil out of these images that was actually found in Carlsbad Caverns, right behind the elevator. Can I get more specific on an ID? Cross section of rugose coral? Sponge? Bryozoan. Acanthocladia? Bryozoan? Crinoid. -
I've been poking around in some Wellington fm micro matrix, permian age, Jackson Co, OK & thought I found a small worn spiral shell, so I put it with the other items I had pulled out. Later, when looking at the items closer, I realized it wasn't a shell & that I had some slightly crappy matrix... literally. A small coprolite 6 mm in length by 4 mm wide & containing what I think are fish scales. So now I'm digging through the matrix again to see if there is any more. The pics are with a dino lite with no photo stacking software, so please bear with them. This is the one thing I never even considerd that I might find in micro matrix.

Hi guys! I don't post here often, but I'm a PhD student in geology, currently working on tropical Paleogene palynology. I'm taking an unrelated class on the Permian Basin and I am working on identifying some of the fossils our class saw in Guadalupe Mountains National Park. I'm not a sponge expert, and I was hoping someone on the forum might be able to confirm or correct my identifications. I might make a follow-up post on the non-sponge fossils we saw on the trip. A bit of background, these pictures were taken in the field with a metric scale, the scale has been cropped out of the pictures and a 5 mm scale bar is added. No fossil collecting was allowed on this trip so I won't be able to provide additional images. The fossils are from the Capitan Formation, which is Permian Period, Guadalupian Epoch, Capitanian Stage. The global stage name is actually named after the nearby El Capitan peak. Amblysiphonella? Archaeolithoporella?
