  1. Hello everyone, I am pretty new to the fossil hunting game, mostly just picking up a few shells or leaf imprints when I am out hiking but when I returned to school in Florida I started to get a bit more interested in actually researching and exploring with the intention of fossil hunting. On the drive back to Florida from Denver I decided to break the trip up into 6-8 hour drive days and camp while hitting some fossil opportunities. Also it kept me fairly isolated with Covid restrictions. With that in mind I planned a route to hit a few different sites: Quay County,

    Fall fossils in TX

    Hello all, My since we just went through Hurricane Sally, my wife said I need to get out and go collecting. Who am I to argue! So I'm planning a trip to north Texas to collect. I would appreciate and help from y'all to point me in the right direction. I have been to Lake Texoma and the Jacksboro once, briefly, in the past and really had a great time there. Any help would be greatly appreciated!
  3. I'm unable to identify these goniatites from the Finis Shale member of the Graham formation. Found at the Lost Creek spillway near Jacksboro Texas. At first I thought they were just extra large examples of Agathiceras sp. which can be found there because of the longitudinal lirae but I noticed some other differences. These are more evolute as well as being larger. They also have a larger whorl height to whorl breadth ratio at 1.11 to 1 compared to .85 to 1 for Agathiceras. This one shows the larger umbilical diameter of 10mm and he
  4. This specimen from the Finis Shale of Jacksboro Texas is the first example of a Pennsylvanian nautiloid showing part of the aperture that I have found or even seen. Maybe they are common and I just don't get out enough I believe this is Stenopoceras sp. and the attached clam is probably Pseudomonotis beedi since that's the only species of that genus I can't find an image of and the others on the fauna list have ribs that curve away from center. You can help me twice if you can confirm the clam ID and show us your nautiloid apertures for comparison. Outside

    Jumbo Orodus tooth

    This tooth came from the Finis Shale at Jacksboro Texas. That's in the Virgil Series, Cisco Group, Graham Formation, Late Pennsylvanian. It seems large for Orodus variabilis and has some extra odd protrusions on the lingual side that don't match the smaller ones I usually find. Is there another species we can find there or is this normal? @JGM
  6. A Russian colleague of Dr. Barbara Seuss will be presenting a poster at the March 2020 GSA meeting in Ft. Worth. It is on Finis Shale fish microremains based on their study of material from Jacksboro Texas. In October of 2016 several of us from Dallas Paleontological Society helped Barbara take sample material for her work and they are still gathering data from the resulting fossils. Dr. Seuss is with the University of Erlangen-Nuremberg in Baravia Germany and hosted another poster by a student of hers at the GSA meeting in Phoenix this year. It was on bivalves also from the Finis Shale e

    Odd Coral from the Finis Shale

    I found this odd horn coral at the Lost Creek Dam site near Jacksboro, Texas. It's Upper Pennsylvanian, Graham formation, Finis Shale member. The horizontal wrinkling seems very organized, looking more like the ornamentation on a conulariid or some orthoconic cephalopods and the presence of dissepiments limit the possibilities some. The bottom was already broken off so I sanded it flat and polished it a bit for a look at the septal pattern but still can't seem to place it in it's proper niche. Dibunophyllum valeriae has been suggested and Lophamplexus sp. but I'm not convinced most
  8. I found this twiggy fossil at the Lost Creek Dam site in Jacksboro Texas. It's the Finis Shale Member of the Graham Formation, Upper Pennsylvanian. I thought it might be a Fissispongia jacksboroensis but now I'm wondering if that is right. The two branch-like protuberances have some wavy striations on them I haven't seen before. Any ideas?

    from Jacksboro, TX

    Found this first one in Jacksboro, TX, Lost Creek Dam. Finis Shale Formation, Pennsylvanian. Would like to identify. Gastrioceras? or maybe Vidrioceras?

    And another from Jacksboro

    Here is another I found at Lost Creek in Jacksboro, TX, Looking for ID help.
  11. 26054-38060-1-SM.pdf Here is a paper by Itano and Lucas about a revision of Camyloprion Eastman, 1902 that includes new teeth found by Mark McKinzie in the Finis Shale member of the Jacksboro Limestone at Jacksboro's Lost Creek site.

    Jacksboro Texas Plants

    I showed Jeffery P the Jacksboro spillway on his swing through Texas and it was my day to find plants in this otherwise marine site. At least I think that both are plants. First this piece with mm scale which I'm guessing could be Cordaites or Artisia pith. Edge view and close-up and other side Next this leaf which I think is one of the seed fern pinnules, also with mm scale other side end views and side views
  13. I'm having trouble getting the right name for this tiny Goniatite from Jacksboro Texas. Upper Pennsylvanian, Finis Shale Member of the Graham Formation. Small at only 7mm.

    Pennsylvanian fish tooth?

    I have bulk sampled many times at the Lost Creek Reservoir in Jacksboro, TX, which is Pennsylvanian material. After dissolving a rock from the Jacksboro Limestone, I found what looks like a fish tooth that is 1.1mm long. In fact, it closely resembles some of the palaeoniscoid fish teeth that I have found in the Permian. Since it is the only one that I have ever found at Jacksboro, there is a chance that it could have somehow been transferred there. Or, although I try to thoroughly clean my screens after each use, I guess there is the chance of cross contamination. I have used those screens to

    crinoid or what?

    I have found these small pacman-like segments at Jacksboro, TX (Lost Creek Reservoir), which is Pennsylvanian, and have always thought that they were a segment from a crinoid stem. I then found what looks like a stem with about 7-8 segments along with more of the individual segments. However, the segments never have any of the radial lines that I often seen in other crinoid segments. Any idea what these are? Thanks.
  16. Another grouping of fossils from the Pennsylvanian Finis Shale Site near Jacksboro, Texas. Always something to find there.
  17. Found this somewhat flattened Brach (Derbyia crassa) in the Pennsylvanian age Finis Shale formation at the Lost Creek Reservoir borrow pit near Jacksboro, in Jack County, Texas a couple of weeks ago. It's not perfect but I love fossils that are still in the matrix and that aren't pristine and show signs of predation and deformation from the weight of the overlying matrix.
  18. I had forgotten I had found Worthenia fossils of this size at the Jacksboro Pennsylvanian period Finis Shale site. Found these probably on my first or second collecting trip to that site 5 or 6 years ago. I have boxes of stuff I haven't looked in for years. Finding stuff that's surprising me.
  19. I had a new look at an old hash plate from the Finis Shale member of the Graham Formation in jack County Texas. It's full of all the Pennsylvanian Sub-period fossils I expected, even a couple of broken trilobite pieces, but this spiral shape caught my eye as I was passing it under a microscope. That's a mm scale in one picture and a human hair in the other. I don't know my micro fossils but I'm guessing it's some kind of foram. Any help with a name?

    Finis Shale ID

    Straight line cephalopod fragments. One stood out. Plant? Finis Shale.

    Articulate Brachiopod

    This is a less common brachiopod collected at the rich Finis Shale site in the spillway of the Jacksboro Reservoir. It is often confused with the more common Composita subtilita which has a stronger sulcus fold and no small spines.

    Jacksboro, Texas bivalve?

    Jacksboro, Texas Lost Creek Dam area, about 1 inch long, Pennsylvanian, Graham Formation, Finis Shale. Need help with ID. Thanks in advance for any help.

    Pennsylvanian oddity

    I recently found this odd item and am trying to determine if it is a fossil, maybe a bivalve, or just geological. I found it at the Pennsylvanian site in Jacksboro, TX at Lost Creek Reservoir. The scale hash marks are 1mm. Thanks for any help.

    That moment when...

    Ah, yes... that moment when you're out hunting, lying on a shale outcrop on a VERY chilly morning, hunting Pennsylvanian fossils & wishing you had worn a heavier jacket than just a thin cotton hoodie... ... when suddenly you hear "tick... tick tick... tick..." and wonder "What's that noise?" ... then you realize it's from tiny bits of sleet starting to hit the ground around you. It got worse fairly quickly, and I had to deal with a 7/10ths of a mile walk back to the car, across a dam, trying to carry my gear & keep my hood low enough across my face that I could

    Pennsylvanian valve from Texas

    This came from the Lost creek Dam site in Jack County Texas, late Pennsylvanian. It looks like a valve of something but I don't even know if it's a brachiopod or a bivalve. It is probably crushed some so that doesn't make id any easier.
