Arbuckle Mountains Oklahoma Bromide Formation Field Trip

The Dallas Paleontological Society is hosting a field trip to the Arbuckle Mountains on June 5, 2022 starting at 8:00 AM to 2:30 PM or sooner if you need to leave before that. 

If you attended the Black Cat Mountain trip, please refrain from registering for this one to allow other members who could not go on that trip to attend this one.

This trip will be for Adult Members only to 2 different sites within the Arbuckle Mountains to look for cystoids, brachiopods, trilobites, bryozoa, Cornulites worm tube, which are a type of Tentaculita, receptaculitid algae, cephalopods, gastropods  and other fauna. The geology is Ordovician in age.

The meeting location and specifics of the trip will be provided to the 10 registrants on Friday evening June 3, 2022. The meeting site is near Ardmore, Oklahoma. These site locations are not to be shared to protect the sites from over hunting. 

The fossils are not abundant in all layers at the sites so that is why we are limiting it to 10 Adult Members. There are lots of fossils, but I, Kim Pervis have not found whole trilobites at the sites. See pictures below for some of the fauna.

Registration will begin 5/21/22, Saturday at 8:00 AM and continues until the event is full. Registration will likely fill up very fast.

One location will require a relatively short, but steep climb and require climbing over large rocks with 2-4 feet drops. Agility and some degree of physical fitness is needed. The other exposure has multiple levels. To move to the next level you must navigate steep areas that have a lot of small loose rocks, which can make it a challenge to not slip and fall on the steep hill.

Since it is June it will be quite warm. Please take into consideration your ability to tolerate the heat, sun and humidity for hours before you register. One site does not have shade. Please bring plenty of fluids to keep yourself hydrated in the heat.

If you have any questions please email, Kim Pervis at fieldtrips@dallaspaleo.org
