    Eryops?

    Hi all, I'm fairly confident that this is what it was describes as, but I just wanted to make sure. It was found in a fossil site in Oklahoma that was formed during a large drought.

    Eryops tooth

    From the album: Permian

    Eryops teeth are conical (this one bears no carinae, though don't know if that's true for the whole dentition), and often have basal creases.

    Permian micro display

    From the album: Permian

    It's remarkable how much of an ecosystem's diversity can be captured in a space smaller than a matchbox. In this case are the likes of Dimetrodon, Eryops, Archeria, Seymouria et al.
  6. During the Summer, I had the fortune of driving near Seymour, TX and thus the opportunity to pay a visit to the WMNH. The WMNH is a small but unique museum in Northern Texas, specializing in the Early Permian fauna that lived nearby ~ 290 million years ago in the famous Texas "red beds." The land around Seymour was once an equatorial bayou, humid and inundated with rivers and lakes. In the rivers were lungfish like those that live today, various ray-finned fishes, and cartilaginous fish like the Xenacanth "sharks." Amphibians like Eryops, Seymouria, and Diplocaulus also spent much of their lives in the water, but were capable of venturing onto land. The most famous not-a-dinosaur Dimetrodon was the terrestrial apex predator, living among other stem-mammals like Edaphosaurus and Secodontosaurus. Early Dinosaurs and mammals were still tens of millions of years in the future. Most of these interesting animals are rarely found in museums, so the chance to see so many of them in one building was an uncommon privilege. Outside the building, a larger-than-life Dimetrodon stands watch over the murals. The building is also lined with large Ammonites. an Eryops tries to find some shade Inside, there are several life reconstructions of some of these animals, the first one being Dimetrodon The first of several Dimetrodon individuals, "Bonnie" The red matrix has been coated with a dark grey material to increase contrast with the bones. There is a partial Diplocaulus amphibian skull in its belly Something I hadn't known: Dimetrodon may have been venomous?? I look forward to the publication of the evidence A couple of large Eryops, their skulls were comparable in size to those of large Alligators Various skeletal elements 1. D. grandis femur, 2. Dimetrodon sp. femur, 3. Edaphosaurus pogonius tibia, 4. Dimetrodon sp. tibia, 5. Edaphosaurus pelvis, 6. Dimetrodon sp. pelvis, 7. Secodontosaurus pelvis Diadectes, a herbivorous tetrapod incisorform and molariform teeth indicate it was capable of stripping and masticating vegetation, a novel development among tetrapods of the time. It also had a secondary palate like we do, meaning it could chew and breathe simultaneously. Diplocaulus, the "boomerang-headed" amphibian Dimetrodon elements Neural spine with a pathology, a healed break possibly from the attack of another Dimetrodon Maxilla with a broken canine, proposed to be broken in life Pelvis with bite marks, possible evidence of cannibalism Another Dimetrodon Some plants
  7. 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!!
  8. 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.
  9. 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.
  10. 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...
