Hi All I though I would do a little post. Sorry if the information is a little lacking but I have been ill and had an emergency operation . I am fine now but still on the meds and I thus get a little confused. I purchased to occupy myself some Micro Matrix from the Lower Permian Richard's Spur locality of Oklahoma. Fossils range from fragments to complete and include toe bones, jaws, skull plates, teeth, intercentra, limb bone ends etc. The majority of specimens are Captorhinus magnus and C. aguti but undoubtedly there are other species. I am sorry but I am unable to identify them but I really enjoyed doing the photos so I thought I would share my finds with you guys. Cheers Bobby

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.- 2 replies

Here is a short trip to keep those of us still in quarantine entertained. I collected this before our quarantine started. Something I have wanted for a while ever since seeing one but was not able to collect was in my trip through Utah's Paleozoic (link here: ) is a trace fossil called Skolithos. For those without much experience with trace fossils, Skolithos is a vertical tubelike burrow in sand on a sandy high-energy beach. The little critters would have to dig relatively deep vertical burrows so that they weren't washed away the next time a storm rolled through. A common name for this particular trace fossil is “piperock” because the number burrows could get dense enough in one area that the rock looks a bundle of straws. Just like a lot of trace fossils, it is not certain what made these burrows but it is known that it probably went extinct at the end of the Cretaceous as there are not any specimens after the dinosaurs’ doomsday. My particular specimen is made of calcareous sandstone that has been slightly metamorphosed into a quartzite. It is most likely from the Lower Permian of the Oquirrh Group based on the location and the nearby rock formation it appeared to have fallen out of but I found it in a gravel pile from the shoreline of Lake Bonneville so the exact stratigraphy is unknown.

Hoping to ID the central object in this photo. It appears to be broken towards the narrower end. It has grooves running the length of it. It's approximately 1 mm or less in length. Lower Permian, Cottonwood member, Council grove group, Kansas.

Thanks to my friend @Jeffrey P ! He had given me some matrix that he collected at the Lower Permian Waurika Oklahoma site on his epic road trip this summer. I have spent some time breaking down the clay matrix, and going through the remaining bits to look for fossils. I've found a few teeth so far, but this was pretty cool. I was putting some hunks of matrix into different solutions to try to break down the clay, and came across this larger solid bit. Upon cleaning it, I realized it mus be a coprolite. It has many inclusions, Orthocanthus teeth, what appear to be bone bits, and fish scales. @Carl @GeschWhat may be interested in this. Enjoy! Matrix from the Lower Permian Wellington - Garbar Complex Note: each square on the background is 5mm by 5mm Coprolite is 2 cm long.

So, I have some more finds from the Permian matrix. A few coprolites, and some teeth. Scales and bones I may put up in another post. Thanks for looking... Squares are 5mm x 5mm Orthocanthus teeth? Miscellaneous teeth ...

Dimetrodon limbatus vertebral sail spine section a.jpg

Dimetrodon limbatus vertebral sail spine section SITE LOCATION: Wellington Garbar Complex, Waurika, Oklahoma, USA TIME PERIOD: Lower Permian (252.2-298.9 million years ago) Data: Dimetrodon (meaning "two measures of teeth") is an extinct genus of synapsids that lived during the Cisuralian (Early) Permian, around 295–272 million years ago (Ma). It is a member of the family Sphenacodontidae. The most prominent feature of Dimetrodon is the large neural spine sail on its back formed by elongated spines extending from the vertebrae. It walked on four legs and had a tall, curved skull with large teeth of different sizes set along the jaws. Most fossils have been found in the southwestern United States, the majority coming from a geological deposit called the Red Beds of Texas and Oklahoma. More recently, fossils have been found in Germany. Over a dozen species have been named since the genus was first described in 1878. Dimetrodon is often mistaken for a dinosaur or as a contemporary of dinosaurs in popular culture, but it became extinct some 40 million years before the first appearance of dinosaurs. Reptile-like in appearance and physiology, Dimetrodon is nevertheless more closely related to mammals than to modern reptiles, though it is not a direct ancestor of mammals.[3] Dimetrodon is assigned to the "non-mammalian synapsids", a group traditionally called "mammal-like reptiles". This groups Dimetrodon together with mammals in a clade (evolutionary group) called Synapsida, while placing dinosaurs, reptiles and birds in a separate clade, Sauropsida. Single openings in the skull behind each eye, known as temporal fenestrae, and other skull features distinguish Dimetrodon and mammals from most of the earliest sauropsids. Dimetrodon was probably one of the apex predators of the Cisuralian ecosystems, feeding on fish and tetrapods, including reptiles and amphibians. Smaller Dimetrodon species may have had different ecological roles. The sail of Dimetrodon may have been used to stabilize its spine or to heat and cool its body as a form of thermoregulation. Some recent studies argue that the sail would have been ineffective at removing heat from the body, and was most likely used in courtship display.
