Looking to get some second opinions on some Permian stuff that I found a few weeks ago. Jefferson county, Waurika Oklahoma. You’ll have to ignore the paint on my hands, I’d been doing some painting prior to these photos. didn’t have a small enough ruler nor a printer, so I just made a small measurement reference. 4x 1/4 inch segments on paper. Claw 1 Most of the claws I’ve found are Trimerorhachis, but this one is definitely an outlier. Claw 2 Likely Trimerorhachis? Claws 3 & 4 Two more, the left is likely Trimerorhachis, but preservation on these aren’t great. Claws 5 & 6 Two more. I suspect the one on the right is Trimerorhachis, the one on the left may be as well but it is larger than usual. will add bones and other stuff to another reply.

Going through Permian matrix. We have found many teeth and other identifiable microfossils. I have also found many of these metallic looking dark rocks. Are they bone fragments, or partially melted rocks? Thank you.

Hello, I recently visited a Permian site near Waurika Pond and collected microfossils for my students to explore back in the classroom. Is there a guide to identifying these fossils out there somewhere or is piecemeal searching here the way to go. If not, I will be making the one page guide over the summer have it to offer. Any help on something simple for my elementary aged students would be much appreciated. IMG_0064.DNG IMG_0065.DNG

All that was on the label for this item was that it’s from the Permian age and from Texas. I don’t have any further info on it. Does anybody know what this is?

Over the weekend I visited a well-known Permian site in Oklahoma in hopes to adding to a tiny collection of Permian vertebrate micro fossils I picked out of a bag of "red bed" matrix I purchased a few years ago from a site in Texas. These sites are Early Permian in age and contain tons of tiny bone fragments of amphibians and reptiles, as well as shark and fish remains. I was hoping to get some help identifying/confirming identifications for some of the more diagnostic bone bits that I collected from the site. Any help would be greatly appreciated! #1- Skull fragment of Eryops megacephalus?- 4cm #2- Vertebra of Archeria crassidens?- 2.5cm #3- Vertebra of Diplocaulus magnicornis?- 9mm #4- ???- 2cm #5- Toe bone of Trimerorhachis insignis?- 8mm #6- Toe bone of Trimerorhachis insignis?- 8mm #7- ???- 9mm #8- Vertebral Spine Spur of Edaphosaurus boanerges?- 1cm #9- Amphibian jaw section?- 8mm #10- Claw of Dimetrodon limbatus?- 1cm #11- Amphibian claw?- 6mm #12- Claw of Trimerorhachis insignis?- 1 cm #13- Amphibian claw?- 1cm #14- Amphibian claw?- 9mm

These are easily identified by the"cross bars" which protrude perpendicularly from the shaft of the neural/sail spines. -
Howdy folks! I’m back for some more identifications, again. Theres not a lot published on my area for tracks/Ichnofossils, so perhaps someone here has seen something or knows what some of these might be. All are Clear Fork Permian from Abilene, Texas. Potential Arthropod? Track, potential Laoporus? Really odd, could be from an animal or might be something else Another oddity. Water droplets? Tetrapods, potential Laoporus or other. Thank you all for any insight! There’s just nothing published about this specific site so it’s been really tricky for me to identify things.

In my continued studies of my local Permian areas, I came across information on a site that I hadn’t been previously aware of. I’m working on a paper describing the outcrops in the areas near to Taylor, Baylor and Archer counties, as well as some close outliers when I come across them. Information on this site Clear Fork (Permian) 298.9-251.902 mya Lots of siltstone at this specific site, which is why there are tracks present. All the fossils came from an area about 10 x 15 ft in an outcrop that has weathered away, there’s lots of siltstone surrounding but the fossils were very specific to one small area of this outcrop. Not entirely sure why this is the case yet, but I’m reading up on it. Lovely view of a pond from atop the hill several feet above the exposure. Looking back down the hill at the localized exposure. A small amount of limestone in the adjacent area. Some of the seed ferns on the ground prior to being picked up. Great spot for splitting the siltstone, the ferns were beautifully preserved in the layers. The haul after being gently cleaned, the siltstone doesn’t stand up well to water at all. Delrnotea Abbotii Seed Ferns I collected lots of examples, but these are some of my favorite. Plant Material There were some examples of layered plant material, perhaps just stems from the seed ferns lying on the ground and decomposing. This one has me stumped, it might be water droplets, but I’m not sure yet. Any information or identification is very welcome! Tetrapod tracks, potentially Laoporus? Other Ichnofossils, they appear to be tracks, and some of them might be arthropod. One looks to be amphibian. Getting lighting to show the tracks is pretty tricky since they wash out under bright light. Some sort of drag marks, very strange. Indeterminate, two toes are clearly visible at the bottom right. Probably not enough to identify. Again, I don’t think enough for ID on some of these. top right This one may not be a track, it lacks the impression that the others have, but it stood out a lot so I picked it up in case. Potential Amphibian tracks, one is smaller and is going the opposite direction of the larger. I’m new to tracks and ichnofossils in general so I could be completely wrong. Not fossils, but these pieces of siltstone were pretty interesting. The white coloration goes completely through the stone. No idea what could cause this. Thanks all!

Permian Amphibian Tracks?
Rikache posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hi everyone! First I want to say thank you to everyone who’s been so incredibly helpful these recent months. As my collection has started and slowly grown, I’ve always been able to depend on this forum for help, guidance, and knowledge. So thank you everyone! I recently came across this “Permian amphibious track” and it really caught my eye. Personally, the Permian period has always been one of my favorites and most interesting periods to learn about so I would love to be able to add something from that period to my collection, especially something this interesting. I was wondering if anyone could give me some insight on whether this specimen matches its description and whether you believe it’s legit. The tracks are said to be from Lodeve, France and are said to be from an animal that resembles todays salamander. Please let me know what y’all think!

Originally the fish was described by Agassiz in 1833 under the name Palaeoniscus vratislaviensis. Taxonomy from Štamberg 2021. Diagnosis of Paramblypterus vratislaviensis from Štamberg 2021, p. 77:”. Small fish usually ranging from 100 to 120 mm, exceptionally to 150 mm. The frontal is 3.5 times longer than wide and 2.5 times longer than the length of the parietal. The anterior margin of the frontal is concave medially, interfrontal suture only slightly undulated and without folds, the sculpture on the frontal consists of ridges parallel with the posterior margin of the bone. The dermosphenotic is narrow, elongated anteroposteriorly. The dermopterotic, with lateral process but without posterior process, is narrower anteriorly than posteriorly. The infraorbital superior, dermosphenotic and supraorbital anterior form the dorsal edge of the orbit. The maxilla has a short and high maxillary plate which is convex dorsally, the length/height ratio of the maxillary plate is 1 or less than 1. The operculum is oblong in shape, 1.4 times deeper than it is long. The scales on the anterior part of the body bear fine ridges extending posteriorly to the denticles. Denticulation decreases on the scales in the posterior direction and the last denticulate scale appears in the 13th scale row. A field of small scales occurs along the base of the anal and dorsal fins.” Line drawing from Štamberg 2021, p. 82: Paramblypterus vratislaviensis (Agassiz, 1833). a: restoration of the body in lateral view, scale bar 10 mm.

The only terrestrial reptile fossil I own: Mycterosaurus longiceps
gond posted a topic in Member Collections
In my collection (about 30 fossils in total, but it's always expanding!) there is only one fossil of terrestrial reptile (but I'm saving some money to get another one soon!) ------------------------------------------------------------------------------- Species: Mycterosaurus longiceps Size: 1 cm x 5 mm Age: 280-275 mya (Lower Permian, Kungurian) Origin: USA, Oklahoma --> Dolese Brothers Quarry --> Richard's Spur About this fossil: one of the smallest ones in my collection, it is a partially complete caudal vertebra of Mycterosaurus longiceps. It is missing only a small piece in the upper part of the vertebra.

Is this real amphibian fossil
Le Quoc posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hi everyone! Recently I have purchased this item. But when I received I saw that the two leg laying in upper layer of the matrix. (Picture below) So is this original fossil or this is fake one? Thank you!

I have been incredibly bad about writing this trip report, so I am glad that I have finally gotten a rainy day to put it together. Back in September, I joined the Paleontological Society of Austin on a field trip to two sites in the "Heart of Texas," one in the Pennsylvanian and one in the Permian. I had never before had the chance to collect in the Permian so I was really excited to go on this trip. @erose did a great job explaining the stratigraphy of the sites and what we should look for. Erich explained that the Permian site was an exposure of the very early Permian Moran Formation. The highlights of the site were tiny enrolled trilobites and rare crinoid cups. The site also had tons of brachiopods. I spent the night in the area so I had the good fortune of collecting the site after most of the other members had left. To say the least, I was really happy with my finds. A big thank you to @Ptychodus04 for the prep work on the crinoid cup and trilobite. Ditomopyge decurata Crinoid Cup- Peter Holterhoff, who has done a lot of work studying and describing the Pennsylvanian and Permian crinoids of Texas, told me that this specific crinoid remains undescribed and that he has only ever seen 2 or 3 other articulated cups of this crinoid Crinoid Plates and Anal Spines Archaeocidaris sp. Plates and Spines Lophophyllidium plummeri Zaphrentis gibsoni Fenestrate bryozoan Derbyia sp. Neochonetes puebloensis Hustedia sp. Composita subtilita Dielasma sp. Condrathyris perplexa Schuchertella pratteni Punctospirifer sp. Rhynchopora magnicosta Reticulatia sp.? Marginifera sp.? Some unknown brachiopods

Over the weekend I joined the Dallas Paleo Society on a field trip to two road cuts near Cisco exposing the Early Permian Camp Colorado Limestone and Watts Creek Shale. The Camp Colorado Limestone had many more brachiopods and I have been able to identify everything to a genus level except for these two. Does anyone know what these are? I initially thought that the second was Derbyia sp. but it seems a little different than the other chunks of Derbyia I found. Perhaps it is a juvenile Derbyia? Any help would be greatly appreciated. Thank you so much! #1 #2

The lower Hunter Valley is underlain predominantly by Permian strata, and encompasses the region around Newcastle, NSW, Australia. It is here that a diverse fossil macrofauna can be found at a disused quarry standing on private property. Mulbring quarry is characterised by excellent exposure of the Permian strata with macrofauna dominated by abundant bryozoans and brachiopods, associated with bivalves, gastropods, and echinoderms. With the weather typically windy this time of year it was no surprise when we hit the black top with a strong westerly wind blowing, fortunately the sun was shinning. The plan was for my family to meet up with my retired geology teacher friend and his wife at the gate to the property. Two weeks earlier I received access permission from the property owner and we met my friends at the gate and headed up the track. Stepping out of the car upon arrival at the quarry our excitement peaked quickly with fossils bearing rock lying all around us. It didn't take long for my friend Col to find a lovely Bryozoan, my find with a specimen of fossil debris, including fragmented gastropods, isolated echinoderm ossicles and small brachiopods (pictured Mulbring 001) followed quickly after. We spent the next couple of hours fossicking around, then stopped for a well prepared picnic in the Australian bush. A few more hours of fossicking revealed the beautiful Bryozoan also pictured (Mulbring 002). These fossil beds also contain a particularly high abundance of fenestellid bryozoans and brachiopods (spiriferides and productoids), with bivalve molluscs the next most abundant. Minor groups include gastropods, rostroconchs, corals, trilobites and several types of echinoderms. Sadly, the trilobites and intact echinoderms evaded our gaze. I've already began my visit to one of the State's Jurassic sites early next year! Cheers Adelotus

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!
