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 mostly because of the horizontal patterning.

Some of us with the Dallas Paleontological Society have decided to initiate a group dedicated to learning more about the Pennsylvanian Period fossils from the Finis Shale member of the Graham Formation found at the Lost creek Dam site near Jacksboro Texas. We hope to meet at a place and time convenient to everyone. You can participate in person or follow our progress online through the DPS website. Go to the home page at dallaspaleo.org to see how to get your name added to the list if you want to join us at the meetings. Please forward this to anyone you know who isn't a member and might be interested. We will begin making plans about when and where to meet with the list of names we have gathered as of August 16th and all decide together what our group will try to achieve when we have our first meeting. There are some things found at the site that are not thoroughly understood, not fully researched or can be difficult to distinguish from similar specimens. We may decide to include topics from other Pennsylvanian sites in the area. We already have help promised from some prominent experts so surely we can learn something new or at least identify possible avenues of investigation for someone interested in taking on a project.
