Jacksboro Study Group

The purpose of this page will be to update any interested members or guests on the progress and news of the Jacksboro Study Group.  

Some of us have decided to initiate a group dedicated to learning more about the fossils from the Finis Shale member of the Graham Formation found at the Lost creek Dam site near Jacksboro Texas. You can participate in person or online through the DPS website.

Please send an email response to me at  brwill@ntin.net  to get your name added to the list if you want to join us. Please forward this to anyone you know who isn't a member and might be interested. 

Jacksboro Study Group            9:00AM

Until further notice we will meet at the U.T. Arlington Geo Science Building room 202 at 9:00AM. Watch the calendar for which day. We try to meet every month on a Saturday. Parking is free on Saturdays at visitor parking spaces and at parking meters on campus.

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. We will be posting pictures and information about items collected at the site from time to time, and also we will be posting meeting times and topics that will be discussed.  Check back here to see the latest.


Thanks to Bob Williams and Ben Nueman for locating these resources listed below.
