I've been going through some of my micro matrix pictures from the Waurika Permian site I visited in May and this little tooth has me thinking it might be Dimetrodon....the shape is possibly correct and there is just a TINY bit of evidence of carina on one edge. Perhaps a juvenile? It's tiny tiny....3 mm . You can just barely see the carina on the left side

please help identify

Hello, I posted previously on a tooth found on a creek gravel bar in central Oklahoma that may be bison or cow. I did some additional looking around in the same area of the creek and downstream about a hundred yards and found the specimens in the attached photos. For reference I am also including a picture that shows where the horn and skull fragment were found (bottom of embankment, indicated by red arrow). I also found a rib bone piece here but am not including any pictures of that one as it was a pretty small piece. The tooth was found in a gravel bar in the stream at the same location. The humerus (pretty sure that is a humerus?) was found mostly buried in stream mud about 50 feet downstream on the same side of the creek. I would be happy if anyone has any thoughts on what these bones originally belonged to. Sorry for the standard tape measure, I don't have a metric ruler at home. Thanks in advance for any ideas!

Hello, I am brand new to The Fossil Forum, so I hope I am doing this all correctly! I found the tooth shown in the attached photos this summer on a gravel bed in a creek in central Oklahoma. I have gotten some feedback from a few folks with experience in bones and fossils locally, with suggestions for possibly bison, horse, antelope or camel, but no definitive answer yet. I am hoping that this forum can provide some additional feedback and maybe a more certain identification. Thank you very much in advance!

Well, 2 days ago I was freezing my butt off in Chicago and today its almost 90 degrees here in Oklahoma! But warm dry weather is perfect hunting time, so I headed out to a ranch I started searching last year. After many hours of walking and eyeballing every bit of rock exposure, something finally caught my eye. I immediately recognized the bone structure, marked the spot and kept searching. More and more bits started to show up and I immediately recognized the "figure 8" shaped that is distinctive of the sail spines of Dimetrodon! This is the animal I have been hoping to find since I began my research into Oklahoma fossil locations. I was super excited. These were found on surface as "float", so I marked every spot with engineer tape. When I couldnt find any more, I stood back and looked at a perfect triangle pointing to the highest spot where I found material, and it was also several bits together. So now I have an arrow pointing to my dig site. My only hope is that I am just finding the tips (since almost all of it was sail spine bits) and the rest of it is still in the ground waiting. Fingers crossed. Even if this is the only parts left, I'm still super excited. Most were sail spine bits and some were BIG, huge compared to what I saw on my day of digging in the Craddock bone bed in Texas. Also a few other bits that might be pieces of rib or limbs. Also, 2 bits of Orthocanthus shark headspine (actually the first items I saw) and 2 coprolites including 1 that has visible bone bits in it! @thelivingdead531 I know its been 3 years, but I'm a heck of a lot closer to finding that Ddon tooth I promised you! My field collection collection Dimetrodon sail spine bit That distinctive shape for sail spine! and another one Everything brought home Not a great pic, but the light spots are bits of bone in this coprolite. Othocanthus spine pieces. Ortho head spine showing denticles 2nd ortho head spine with denticles

It's been a couple of weeks but it's taken me this long to take all the photos of my fossil finds from my trip to Oklahoma with the Paleontological Society of Austin! Our yearly trek to find Silurian, Devonian and Ordovician finds (not much of that in Texas!) was a great success again, thanks to our OK friends! Since it's just over a 6 hour drive for me, I went up early on Friday to hit a couple of "non field trip" spots before our "real" field trip on Saturday and Sunday. I had heard about a Permian site that I was excited to check out. It's a weird barren moonscape in the middle of a field. It was a bit warm.....and the sun radiating up from the baked clay was....intense. Fortunately a cold front was on the way so I kept reminding myself that the 90's of this Friday would recede into memory. But yeah...it was hot. There were bone bits everywhere....everywhere! But they were pretty crunched up. I didn't find much more than a few not-well preserved vertebrae, some okay bone bits, a few nice little amphib teeth and a couple of quite nice unbroken orthocanthus teeth. Tiny tiny ones, because all the big ones break easily. While I didn't find a lot of quality stuff initially, I did haul out about 60lbs of matrix so I can look through at my leisure at home! I learned a valuable lesson though...take two smaller buckets rather than one large bucket. It's a LOT easier to haul out two 30 lbs instead of one big haul a quarter mile over rough terrain! A little amphibian tooth: EDIT:...I thought these were Amphib teeth, but apparently....they are Orthocanthus Shark coprolites! hahahhha They are 1/4 inch each What is most amazing about these fossils is the color of the preservation. Astounding reds, yellows and purples. The little Orthocanthus shark teeth that were mostly complete. The Permian "moonscape": I decided to hit one other site before I headed to Ada where we were all meeting. It was the Ordivician site that I found a lovely Oklahomacystis echinoderm last year. The cold front had moved in and the temperature dropped almost 20 degrees and was just LOVELY hunting! I didn't find any more Oklahomacystis and wasn't finding much except a few nice brachiopods, but then I saw a crinoid calyx piece upside down (all I saw was the edges but I recognized it as crinoid) picked it up and got a nice surprise!! Too bad it's not the whole thing and just one segment, but I'll take what I get! It's a beauty...the geometric patterning is amazing. It is a Pleurocystites echinoderm. It's 1 1/4 inch wide. Early on Saturday, the whole group goes to Yellow Bluff which is a huge area above a creek and up a hillside. It's a great site with a plethora of fauna. It is completely possible to spend an ENTIRE day there! But first we had to drive through the pasture and the cows! They were nice cows. Yellow Bluff - It is primarily Silurian with a cap of Devonian at the very top of the hill. It is Henryshouse formation (which I keep wanting to call Harryhousen.... hahahha - that's for any of you old school animation lovers out there) And not only were the fossils abundant, so were the Missouri Primroses! A few nice finds in the field- A Gastropod Platyceras, Crinoid cup - I think this might be Ollulocrinus? A pink Brachiopod! Here's that pink brach again: I found a couple of Trilos, nothing quite good (last year I found the best one!!) but I did find one large one which still has lots of matrix on it, an interesting half a one, split vertically, not horizontally and then some others not very well preserved. This is an odd bit of crinoid : not sure what it is: So aside from the above pics of the in situ pieces, my only other really good find was this brachiopod Dictyonella. It was originally thought to have a bryozoan growing on it, but turns out it is actually the pattern of the brachiopod! There was also this cool bryozoan which I thought was a horn coral when I picked it up, only realizing it was bryzoan as I photographed it! It's 1 1/2 inches in size! But I did bring home a bucket of matrix and am having fun going through it, so will post some of those at a later time. Oh, and there were scorpions out and about enjoying the cool weather too. Hopefully no scorps in my bucket of matrix..... if so, now they are Texas Scorps. So Sunday was Black Cat Mountain Day. If you are not familiar with the trilobites from Black Cat Mountain...you are in for a google treat. Of course, finding the rare trilobites is.....rare. But there are plenty of other amazing things to find at Bob's quarry! The Quarry is Devonian with Haragan and Bois D'Arc Formations. But the trilobites are of course, the favorite. While I love the rollers the best (not sure why, I just do) I actually found better "open" ones this time than rollers! All of these are about an inch long. Paciphacops sp. Kainops sp. and not sure what this one is...probably Kainops and a surprising find of a (sadly not complete, but more complete than the typical) Huntoniatonia huntonensis Usually you just find the pygidiums...they are ALL OVER THE PLACE and they get HUGE. The biggest pygidium I found was 2" x 2"...just the trilobutt! It would have been a monster trilo. But the brachiopods are almost as amazing as the trilos. My favorite is this Howollella (I think) covered in Beekite: This is a big silicified Anastrophia (1 inch) An interesting Meristella with some crystals Orthostrophia and a neat coral which I think is Syringaxon perhaps? And one of my favorites to find - straight shelled cephalopods. This by far the most intact one I found. They are usually only three or four chambers but can get to be almost an inch in diameter. This one is 5 inches long And finally , my other favorite find from Black Cat Mountain.....a beautiful bryozoan ring:

Found on a sandbar in the middle of a creek in north central Oklahoma. Still new to all this and at least 2/3 of what I initially think are fossils turn out to be rocks so I’m just looking for the opinions of those who know better than me.

There really aren't any great ID guides online for this site. There's one but i read it was unreliable. Looking for some pointers on these. Sorry, but this is going to be fairly long. 1. Lungfish scale 2. Fish spines? 3. Shark denticles? 4. Amphibian teeth? 4a. 4b. 4c. 4d. 4e. 4f. 4g. 4h. 4i. 4j. 4k. 4L. 4m. 4n.

Found this odd little thing in my Micro matrix I brought back from Oklahoma - Silurian Henryhouse Formation. It looks crinoidy, but I know there are starfish that can be found in this formation too. Any thoughts? Aprox 1/4 inch

It’s been a while, but now I’ve got something worth posting about that I’d like identified. :) Took a trip to Lake Texoma yesterday and my husband found this. My guess is some kind of bivalve, but I’m hoping that someone here has a little more knowledge.

My latests hunts to my Permian sites have been slim. Still trying to narrow down the producing layer(s), but my test excavations have been dry so far. If you remember in my last thread, one of my spots was almost buried by overburden from a dozer work above. I had a strong hunch that there would be fossils in those debris pile and I just needed some rain to start washing it down. I was right! We have been getting quite a bit of rain lately and its helping uncover more. Last week I found a couple pieces of an Orthocanthus texensis (Permian age shark) head spine. I have found many pieces like this at this site, but these 2 parts went together making about a 3 inch long section. My biggest piece yet! Today, 2 more pieces were found. This section had lovely denticles! While cleaning and talking about them with my son, I got out the last section to explain the how the complete spine would look with the smooth lower, and barbed upper pieces.... AND THEY FIT TOGETHER! What made is more amazing was that the base section was found very high on the pile, and the barbed section was at the bottom. The break on the tip is recent, and I have hope I might still find the last 1.25 inches to make this 100% complete. I might just try digging and sifting for it. Its a narrow water-dug path these came from. The base section was wedged sideways up high, maybe the tip was flushed all the way down along with the most recent find.

I found this in Southeastern Oklahoma. I found it at a lake. It was showing due to the water levels being down. I've contacted someone down in Keene, TX about it and they said there is a possibility one or both are acrocanthosaurus tracks or trace tracks. They have found tracks up in Atoka County. Which is 45 minutes away. There are tracks, also,also, a museum in Idabel, OK. Then, if you head south, there's dinosaur valley state park. Where you can view tracks in the river. I explained, to the person who specializes in this stuff, I moved it, but took documentation of where I found it. So the water could no longer erode it. There is a museum close. It is about to start their Dino Days again. I really want to go get it checked out. I've cleaned the piece up since I brought it home last year. But I'm afraid I will do damage. I want to clean it, but not destroy it. We have some ammonites we have been cleaning. Those seem a lot easier than what is going on with the possible track. The light colored rock, is another possible track found near the other one. Facing a different direction. This one I could not move. Is this my mind just playing tricks? Or did I possible find something? Either way, it has been a fun experience and practice, for me.

This came from the Deese Group of central Oklahoma. It seems a little long for a conodont at 7 mm but it doesn't look familiar to me. Any ideas?

I want your opinions on this piece. I picked this up today, after knocking it a few times to make sure that it wasn't "fresh". The surface texture it really rough and funky. Very much like sandstone and not what I'm used to with fossils here, but the shape... come on, how can this NOT be what it looks like? Found at my 280MY Permian site. Whats your thoughts? Is it coprolite, a very grossly shaped natural rock, or should I go wash my hands some more?

Found in Southern Oklahoma among other Pennsylvanian fossils, crinoids, brachiopods, etc. Specimen is .5cm across. 6 sided. Looking for help with ID.

Hello, Could I get an ID on this piece? Permian-aged from the Ryan Formation near Waruika, Oklahoma. It's labeled as a reptile jaw piece. Has three teeth that are laterally compressed and somewhat twisted with serrations (Apparently there are serrations only on one side of the teeth). I wonder if it's shark and not reptile at all. Pathological shark tooth perhaps? Size is a little over 1cm. @jdp

These photos are of what appears to be a large fossil found in my hometown in Hughes County, Oklahoma. I have not seen them in person, but I trust the person who posted the photos. The rock is large and initially looks like a spine, but I know that concretions can be misleading, too. I am going to reach out to him and try to find out if it was found near a current water source or not, if that helps. Thanks!

Sunday the 26th I took part in a DPS field trip to a plant site in Oklahoma. The locality is in the Savanna Shale which is Pennsylvanian Period, Desmonian (Desmoinesian) stage, 306-308 mya.
