  2. Pennsylvanian Find ID Help Needed

    Hello all! I'm in the process of cleaning my finds from my treasure hunt yesterday in Jacksboro, Texas. I would appreciate y'alls help on this one! Any ideas? I know it's Pennsylvanian - doesn't look like anything else I found that day (variety of crinoids, corals, brachiopods, gastropods, some echinoid plates & spines, the one awesome shark tooth). I don't know what this bad boy is but it's pretty cool. It is the size of a penny.
  3. Jacksboro, Tx Shark Tooth Find

    Had a great fossil hunt today in Jacksboro and wanted to share pics of an awesome shark tooth I found. The team identified as Orodus variabilis. So excited - finding a shark tooth has been on my "fossil bucket list" for a long time. For size comparison, it's about the size of a penny. I'm just thrilled, it's beautiful!

  6. What Are These Cylinders?

    Here are some others that I need help with from Jacksboro, TX, Pennsylvanian, Graham formation, fins shale......These are some examples of items that are quite common in this area.....They are cylindrical, with a definite center core running thru the specimen and seem to have "growth lines" on the sides, almost like orothocones, but the lines are not as straight. All sizes are abundant. 1. 2. 3. 4. 5. 6. 7 . 8 . I have had several suggestions of what they are, but none are in agreement. Again, Thanks in advance for your help.
  7. Several From Jacksboro

    I found these items in Jacksboro, TX, Pennsylvanian, Graham formation, finis shale.....and I need help identifying.... The first looks like coprolite, but has crinoid features on the very end.....maybe worn byrozoan on crinoid???? 1. 2. See the Crinoid features? The second I have no clue. Looks like an oyster of some sort, but is not like others I have found in Texas. 3. 4. 5. Thanks in advance for your help.
  8. Found this last weekend in Jacksboro, TX. Pennsylvanian, Finis shale, Graham Formation. Is this a brachiopod? or something else....one inch deep, two inches wide, found with other brachs, crinoids, and other marine material, Thanks in advance for your help.
  9. We have these 3 little bits of mystery fossil from Jacksboro, Tx. Does anyone know if they are fossilized plant, seed, crinoid part, or maybe even a starfish/asteroid arm segment? The scale is finger sized.
  10. 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)
  11. Rudist Clams?

    Found these as well in Jacksboro. Finis shale, Pennsylvanian. Looks like pictures I've seen of Rudist clams. Or coral? Any help would be appreciated. and on the back: Thanks in advance for help.
  12. Jacksboro Finds

    Found these in Jacksboro, Texas, finis shale formation, pennsylvanian, and need help with ID. and these: and finally these: Thanks in advance for your help.
  13. I found this at the recent Jacksboro Trip in Texas. It is Finis Shale and is from the Pennsylvanian Period. I know there are a lot of members that hunt this period and also the Jacksboro site. I posted these pics on the thread regarding the trip but thought it might be better to get an ID on this section of the forum. I am hoping someone has an idea. Found in association with echinoid plates and spines. The first image is for scale.
  14. Also From Jacksboro

    Found this also in Finis shale of Graham formation, cisco virgilian series of upper penn, in Jacksboro, Texas, This specimen is one inch long. Lots of Nautiloids, Conularids, brachiopods, in the area. Any ideas??
  15. Here is a collection of varied specimens I collected at Jacksboro Lake a couple weeks ago in the Finis Shale. A mixed bag of: crinoid, brachiopods, pelecypods, gastropods, fusilinids, ostracods, bryozoan, corals, worm tubes, echinoderm spines, foraminifera and stuff I haven't ID'd yet.
