Jacksboro, Texas is a located in an area of Carboniferous
Period geology which dates to circa 280-360 million years ago. This
Period is PRE-dinosaur when large sea creatures, amphibians, large
insects, and relatively small land reptiles were dominant.
On my first trip I found many nice shells of extinct mollusk species and
various crinoid stems.
