  1. Fossil Sites in Sequoyah county?

    Any good spots in Sequoyah county? I've spend some time in Adair and Cherokee counties and have found numerous crynoids and the like. I recently have found a foot long, or so, Stigmaria around Tenkiller Lake which has sparked my curiosity to find more plant based fossils in my area. Also, any good spots for a trilobite? I've been looking for years (in all the wrong places, I'm sure)! Thank you!
  2. As found, both Leon Theissen and I thought it looked perfect... What started out promising, alas was not to be. Tail spine - check, thorax points - check, caphalon - MIA
  3. Mollusk ID Requested

    All, I found this fossil in a shale deposit of Pennsylvanian age in Northeastern Oklahoma. The shale is probably Chanute formation and contains other marine fossils. I would appreciate any help with ID. Best wishes.
  4. My wife and I went on a 7500+ mile ramble to break out of our COVID doldrums. Due to the virus we had to change up many of our original plans... which conversely added a number of additional fossil hunting locals as they allowed us to mostly avoid our fellow humans and maintain social distancing by many many miles. As part of our trip preparations my wife sewed us a number of masks, including a whole series of fossil hunting masks for me. Originally we were supposed to stay in Chicago, but we elected to avoid staying in the city, so we only got to do a drive by We started the trip with a bonus dig, meeting up with fellow forum member @minnbuckeye for a guided Ordovician hunt in Fennimore, Wisconsin (THANKS MIKE!) Unfortunately I neglected to take pics of the site so I will only be able to share a farm pic we passed on the way. Mike was a gracious host who kicked off the visit with a gift of several fossil samples from his home turf As with all of the fossils from this trip, all finds are as they arrived back home, no prep. Some of our finds from Fennimore:
  5. help id this fossil

    Lots of rocks with tiny fossils. This was on one of these rocks. Most of the fossils are Crinoids but this looks like something else Any ideas?
  6. Lots of rocks with tiny invertebrate fossils. This object was loosely attached to one of these....is it just most likely sandstone with a unique shape? (about 1/2 inch long)
  7. Well, I have just found out that a prehistoric shark I have always been fascinated with can actually be found in my home state! Unfortunately....I no longer live there! I would love to get my hands on one just to bridge this nostalgia with a piece from home and am happy to work out a trade or the like as necessary. So if anyone has a Stethacanthus shark tooth from Oklahoma and they are interested in trading, please message me! I unfortunately have hardly anything in the way of fossil shark material, but I might have something else that could be of interest. If there's any other obscure shark teeth from Oklahoma I don't know of (besides Barbclabornia and Orthacanthus), I'd be interested to learn more on them as well Always learning new things!
  8. I finally finished going through my Oklahoma Permian Matrix from PaleoTex LLC! SO MUCH STUFF! I went through it the first time just with eyeballs (with the help of reading glasses). Then I realized I should use my microscope camera (which runs through my computer which is AWESOME) and see if I missed anything. OH MY GREAT GOOGLY MOOGLY I missed a lot! So here are some of the really "minis" from the matrix! Most are so small that it just couldn't even get a pic with my scale, some are less than 1 mm - a speck of dust! . I need to get a millimeter scale, though, for sure. So here are some more finds from the Oklahoma Permian: Mycterosaurus tooth : 4 mm Chevron Bone (part of the tail of an amphibian, I believe? 4 mm A Doleserpeton toe bone! So very tiny. You can see how small it is compared to the 4 mm chevron! I think this is an intervertebral thing? 2 mm Unknown tiny tiny. Can't seem to find out what this is, but I thought it was really really cool looking . It was literally the size o a speck of dust.... which sadly meant I lost it after I photographed it....it just disappeared. a lovely bone. 3 mm Jaw plate...i loved the blueish enamel: 3 mm Same with this "blue tooth" - probably Cacops, I think? 3 mm Another Cacops tooth: 4 mm An unknown jaw fragment: 3mm Captorhinus tooth? 2 mm Doleserpeton jaw plates biggest 2 mm and lastly a Diadectid tooth There are so many more little bones and teeth and jaw plates and vertebras and skull fragments!! Needless to say, it's been great fun looking through all this tiny matrix. i am totally hooked on it!
  9. Folks, I found this fossil mollusk from a shale deposit in Northeastern Oklahoma. The shale is of Pennsylvanian age (probably Chanute formation), and contains other marine fossils. I would appreciate any help with ID. Best wishes.
  10. Fossil Locations

    I'm looking for some fossil sites that are about an hour to two hours around Blanchard. I'll collect just about anything and really just want to find some spots. I also am a little confused on laws regarding fossil collecting in Oklahoma, so if any one has any info on that I would love to hear.
  11. Folks, These photos are from a small section of shale I picked up in Northeastern Oklahoma. The shale contains marine fossils of Pennsylvanian age. I have questions about a couple of the labeled objects. I’m thinking the center one may be a brachiopod (or possibly a bryzoan--it's hard to tell because of the crinoid plate resting above it). The one on the right looks to me like a bryzoan. However, I’m a novice at identification so I’d appreciate any opinions. The putative bryzoan appears to have grown on the crinoid stem. Best wishes.
  12. Bison?

    First,I hope I’m not doing this wrong, but had trouble posting in Fossil ID for some reason. I hunt a several mile portion of the Arkansas River in Tulsa, Ok. I’ve previously gotten help with identification from the University of Oklahoma on a number of Bison bones, vertebrae and horns, as well as bones from smaller vertebrates. However, that’s a lengthy process, so I was hoping for suggestions on what this bone may have belonged to. It’s shiny because it’s been coated with clear enamel. I’ve had it for several years, but it just occurred to me that it’s dissimilar to my other Bison bones. Obviously, there was some deterioration before it began to mineralize, and one end is missing which makes it very hard to ID. Any help or suggestions is much appreciated! I can take and add more photos if anyone wants, just let me know what angles, etc. Thanks!
  13. I posted some of my finds from the Texas Permian in the Box of Matrix I got from PaleoTex LLC and now I get to share some of the cool little stuff I've found in the Oklahoma Permian! Texas Permian had lots of sharks teeth, Amphibian teeth and interesting boney bits. The Oklahoma stuff is not nearly as "productive" as the Texas Red Bed matrix, but it has LOTS more complete bones and vertebrae! And some really nice little jaws with teeth! Here are a few of my favorite finds. Most are about 1/4 inch, some smaller, a few a bit larger. Amphibian Bolterpeton Jaw and teeth 1/4 inch Amphibian Captorhinus aguti Jaw and Teeth: Synapsid Mycterosaurus Tooth and Jaw Fragment 1/4 inch Unknown Amphibian Skull Fragment (the two round knobs are where the vertebra attached) 1/4 inch Another Unknown Amphibian Skull fragment: 3/8 inch LOTS of little bones! A nice full rib Vertebraes: Myceterosaurus Caudal Vert: 1/4 inch An interesting Vert that looks like an old Victorian Door Knocker! hahaha Probably Captorhinus 1/4 inch Another Captorhinus Vert 1/4 inch An unknown Vert: 1/8 inch
  14. Unknown vertebra?

  15. All, I wonder if someone may have an opinion about the object(s) in the small nodule shown here? The entire nodule is about 0.63 inch wide x 0.75 inch long x 0.5 inch thick (1.6 cm x 1.9 cm x 1.3 cm). It came from an area of shale that is likely of Pennsylvanian age in Northeastern Oklahoma. The shale from this location has many fossil marine invertebrates. I'm assuming its a mineral formation, but any thoughts would be appreciated. It is very hard to get the 3-D relief to show up in photos, so several angles and lighting conditions are shown. Best wishes.
  16. Fossil ID

    Have been doing some fossil exploration in Oklahoma and found the following. Would welcome any help in the ID. Thank you.
  17. Fossid ID Requested

    All, I wonder if someone could help with an ID? The fossil in the pictures is about 0.75 inch (1.9 cm) wide x 0.75 inch (1.9 cm) long. It is about 0.125 inch (0.3 cm) thick at the two large “horn-shaped” raised areas. It came from an area of marine fossils (crinoids, corals, brachiopods, bryzoans) in shale that is likely of Pennsylvanian age in Northeastern Oklahoma. The fossil seems to have two small parallel ridges running through the middle where the halves meet. Also the left and right sides are roughly symmetrical. These features make me wonder if it comes from the midline of some organism with bilateral symmetry. Any thoughts would be appreciated. Best wishes.
  18. Invertebrate ID help requested

    All, This is my first post, although I have been reading with interest for some time. As I approach retirement, I find myself returning to the hobbies of my youth, including fossil hunting. I found these fossils in a single rock in Northeastern Oklahoma (a few miles South of Tulsa). It came from demolished concrete structure, so I do not know where the rock originated. The rock is very hard and very fine grained. It reminds me of chert or a very hard limestone. The first photo shows one end of the rock, where the closeup photos were taken. The fossil in the upper left is about one inch (2.5 cm) in length and about one-half inch (1.3 cm) in height. The second photo shows a close-up of this fossil. I am nearing the file size limit, so I will attempt to reply to this topic with additional photos. I would be grateful if forum members can help me with identification. Best wishes.
  19. OK, I need some help on a fossil I uncovered today. Details: north-central OK, Permian (mid to lower), Wellington fm, in a slab of mud/sand stone with claystone inclusions and acid reactive. Lots of plant material and partial tetrapod skull in this large slab. With all that out of the way, I hope someone here can give me an ID on this tiny bugger. Its roughly 4mm across. I'm really at a loss for what this is. The only thing that comes to mind is that it might be a vertebra. The two processes (extension) are curved, giving it the appearance of an elephant skull. You can see there is a fresh break at the centrum. Before it broke, is was nicely rounded and whole. So experts, what your opinion here? Vert? reptile? amphib? fish? not a vert? One last thing. Both this, and the skull frag, have a weird deep red coating on the surface. In a way if annoying as its a little harder to get through than the rest of the matrix, but then again I know when I'm getting very close to bone because of the color.
  20. Wister Ok - Pennsylvanian

    Found this items this past weekend on my property in Wister Ok. The area is Pennsylvanian and I am not sure what this is or if it is simply a cool geological piece for the flower bed.
  21. Permian fish spines in coprolite

    Hi all, I have been going through some of the coprolites in my collection in order to catalog them. I have two different specimens that have fish spine and scale inclusions. They are from Waurika, Oklahoma (Permian). 1. I want to verify that this is a fish spine. If so, could it be from a Xenacanthus?. Does anyone know if Xenacanthus had scales? The coprolite contains numerous scales. Of those that are visible, this is the best preserved. 2. This coprolite has a different type of fish spine. Any idea what type of fish it is from? That may be a tooth poking out above the spine. Based on the size of the coprolites, I'm assuming the coprolite producers were feeding on fry. As always, thanks for you help!
  22. Planning another summer ramble across a wide swath of the US for siteseeing and fossil hunting. Going to hit some previous sites like Kemmerer and Big Cedar Ridge in Wyoming along with planned stops for a guided dino excursion at a private ranch in eastern Montana and a trilobite dig at Theisen quarry in Oklahoma. I will be zigzagging across much of Montana and Wyoming and would be interested in other suggested stops on the way if anyone has anything they are willing to share. Not looking for someones secret stash, just publicly known places the wife and I might be able to stop for an hour or two as we roll through. We will also be traveling through places like western Nebraska, Oklahoma, southern Alabama, etc. I am interested in any era, invertebrate, vertebrate, plant. Looking to expand my personal collection and maybe pick up a few pieces to trade or auction off here. I have the most flexibility while in the north, but I have been trying to see if I can detour to squeeze in at least a little Alabama carboniferous as I have seen many beautiful specimens posted and I love plant fossils. We shall see. I have the rockhounding guides for the northern states and have tagged several possibilities, I have also been combing through previous posts and searching other references online. I would love to identify an ammonite location along the way as I have never managed to collect one myself. Thanks in advance, Randy
  23. Lake Eufaula OK

    Will be heading there next month for a couple of days. Anywhere close to do a little fossil hunting?
  24. Trace fossil?

    I found this in our property southeast Oklahoma. The area is Pennsylvanian in age. My first thought was that it may be weathered barite (Rose Rock) which is the state rock. However, they are Permian in age and not found in this area to my knowledge. Now I’m thinking either weathered chrinoid (calyx?) maybe a cluster of burrows, or just a really cool looking rock. Any help would be appreciated. The item is 4” x 5.5” in size.
  25. Oklahoma Trilobite

    This trilobite is labelled as Viaphacops from the Bois D'Arc Fm., Devonian, Oklahoma. Can anyone confirm and perhaps assign a specific epithet? Scale in mm.
