  1. 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 exposures at Jacksboro.
  2. A new type has been added to the two lagerstätten used now. A "conservation lagerstätte" features exceptional preservation without much diversity and a "concentration lagerstätte" has extraordinary diversity without notable preservation quality. To recognize sites that have very good but maybe not exceptional preservation as well as a level of diversity that exceeds the conservation type we now can call some sites a "liberation lagerstätte." Anyone like myself with an interest in the Finis Shale member of the Graham Formation found in Jack County Texas will not be surprised to hear it is being recognized as special. Another formation in Texas as well as some in the deep south of the U.S. and others abroad are included in the list from the article presented at the 11th North American Paleontological Convention this June.

  3. Possible Texas Bactrites

    I found this at the Lost Creek Dam site at Jacksboro Texas. It is the Finis Shale Member of the Graham Formatoion in the Upper Pennsylvanian Sub-period. I don't often find the apical end of any nautiloids so I was thinking it could help with the ID. There is a dark spot on the oral end that may or may not be the siphuncle, it is not clear. I thought it may be a Bactrites but it would be one without the hemispherical apex and constriction you see on some. It also has a cameral ratio higher than some Bartrites at around 3. I don't know what the black dots are.
  4. The Heard Museum in McKinney may not be the first place you think of for viewing fossils but they have a growing collection of locally found specimens including an Oligocece tortoise with an unusual view of the inside and a mosasaur left partly in the matrix to show how it was found. A couple of years ago they also started a program especially for amateur collectors. It's called "Collect it Yourself" and shows visitors what is possible for anyone with an interest in fossils to accomplish. Every six months a new collector brings enough material to fill the two display cases they set aside for this program and this time they are showing some of my collection from the famous Lost Creek dam site at Jacksboro Texas. The Finis Shale is a member of the Graham Formation in the Late Pennsylvanian Sub-period and is known for it's fossils with excellent perservation and an incredible level of diversity. I got lots of help with identification from Dr. Benjamin Neuman of Texas A&M University at Texarkana and other members of our Finis Shale Study Group hosted by Dr. Merlynd Nestell of U.T. Arlington. Lynne Hubner is the head of displays at the museum and did great job of arranging the 100+ fossils and making labels. All of them fit into one case except for one very large clam that filled another smaller case. The display will be there until some time in April. If you find yourself in the area this is a great place for a family stop. They also have hiking trails and many programs for all ages. here are the first two images of the display.
  5. Pennsylvanian Goniatite from Texas

    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.
  6. Jacksboro Texas Goniatite

    I having trouble finding out what Upper Pennsylvanian Goniatite this is from the Graham Formation, Finis Shale Member. Found at the Lost Creek Spillway site near Jacksboro Texas. It is very evolute with the whorls barely overlaping. This view shows the compressed whorl section with a rounded venter. These show the flanks with sutures The venter and a rough drawing of the suture
  7. Another grouping of fossils from the Pennsylvanian Finis Shale Site near Jacksboro, Texas. Always something to find there.
  8. 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.
  9. Finis Shale ID

    Straight line cephalopod fragments. One stood out. Plant? Finis Shale.
  10. Update on Lost Creek Dam--Lake Jacksboro

    Gary and I went out to Lost Creek Dam yesterday. We paid our park fee and hiked the dam back to the pit. There were new signs on both gates that read "Danger--Authorized Personnel Only." I called the park office and they weren't aware of the change and suggested I call City Hall. I did, and after I asked about possible rule changes I was put on hold for 7 minutes. Another woman came on and had me repeat my question. She told me we could hunt, but they wanted to be notified in advance. She took my name and phone number, and a head count. I asked her if I could disseminate this info on various forums and groups. She encouraged me to do so. Sorry, but I didn't get her name. I also don't know how the new rule applies to minors. To tell the truth I think it was made up on the spot. Just a heads up.
  11. 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.
  12. Unknown from Jacksboro Texas

    I found this at the Lost Creek dam spillway in the Finis Shale of the Upper Pennsylvanian at Jacksboro Texas. The patterns remind me of cartilage. other side edge more photos in reply
  13. 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 still see, without getting nailed in the face by the rather sharp bits of ice raining down. They were at minimum 1/16th of a inch in diameter, and REALLY stung. Some were even painful through my sleeves! This was NOT in the forecast! (I wasn't alone in this misadventure, but am not naming the other person, unless said person wishes to ID themself.)
  14. 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.

  18. 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 suculus fold and no small spines.
  19. Articulate Brachiopod

    This is a large specimen of a common brachiopod with encrusting Serpula sp. collected at the rich Finis Shale site in the spillway of the Jacksboro Reservoir.
  20. I have three groups of fossils from Texas to trade. I am mainly interested in trilobites, Megalodon teeth, and Ammonites but I will accept other fossils. The first group is from Lake Texoma. It includes an unprepared ammonite, a idiohamites ammonite, a partial ammonite, echinoids, clams and an unprepared echinoid.
  21. Bullet-shaped Pennsylvanian Fossil

    I found this possible cephalopod in the Upper Pennsylvanian Graham Formation at the Lost Creek dam Spillway near Jacksboro Texas. It is 30mm long with a round profile 12mm across. The arrow in the picture below points to a portion of the inside layer that is broken away from the internal mold. The arrows in the picture below point to two more layers outside of the first. Here is a fourth layer on the outside of the others. Here you can see the layers on the blunt end This is the pointy end The ridges in picture below are the only hint of any ornamentation. At first I thought it was one of the enigmatic burrows we find there but they don't have all these layers or these ridges going around the shell just occasional linear grooved linings.
  22. Brachiopod from Jacksboro, TX

    Looking for help on an id for the following brachiopod from Jacksboro, TX. Scale is in centimeters. Formation is the Finis Shale of the Graham Formation, Pennsylvanian. Thanks in advance for your help.
  23. Jacksboro Texas Mystery

    I have no idea what this could be. I found it at the Lost Creek Dam site in the darker shale on the east end of the slope. It's 11mm long and has a very shiny, dark surface. This end is distorted. Other end.
  24. Jacksboro

    I packed my backpack and loaded my stuff into my friends car. We ended up getting there too late so we had to drive around for 20 minutes to find the site. When we got there it was a long hike to get to the site. I started finding a lot of gastropods. I picked up mabye 20 to 30 of them. I also found a lot of bivalves and Brachiopods. Then I found an amazing Worthenia Tabulata. I found a nice cephalopod fragment. Later on it was almost time to leave and I ended up finding three conularia's. It was a good trip!
  25. The Dallas Paleo Society just had their annual field trip to the great Finis shale exposure at Lake Jacksboro. Roz and I went and I recognized DPS regulars BobWill, PollyM, JohnC, MarkM, and a few fairly new people. The group was about 15 adults and several kids but most everyone left pretty early except us and 2 others. I found 5 shark teeth (3 types) in various levels of complete-ness (typical) and a few really good invertebrate shells. This gorgeous large "Worthenia" was the first thing I spotted: brachiopod: "Conularia": "Brachycycloceras" (not the current name): "Petalodus" tooth (only found root and half the blade) "Cladodus/Symmorium" tooth (found 3 bases) "Aggasizodus" (old name) symphysial tooth? (Chondrichthyphiles please help with this)
