Black Cat Mountain Quarry field trip with Dallas Paleo Society, 3-18-17
DinoMike posted a topic in Fossil Hunting Trips
On 3-18-17, Dallas Paleo Society had a field trip to the Black Cat Mountain quarry in Coal County, Oklahoma. Here are a few of my finds from the trip. The details on the site are as follows: Harangan and Bois D'arc formations. Age: Lower Devonian, approximately 419.2 to 393.3 million years ago. Brachiopods, and what I think may be some form of coral. Other side of the brachiopods, same side of the coral piece. Other side is just bare rock. Crinoid columnal section Brachiopod bits & crinoid columnal section Random broken bits on a hash slab, brachiopod shells at top. Brachiopod, Leptaena sp. Thanks for the ID help, @Kane!
