What we’ll find:


Lake Jacksboro Spillway


We will be hunting the lower sections of the Graham Formation, Upper Pennsylvanian. This 300 Mya outcrop represents one of the most richly fossiliferous exposures of marine shelf sediments in the United States. Fossil material that can be found include corals, brachiopods, gastropods, nautiloids and some shark material. You will have to walk a quarter mile across the dam and climb a fence. You will need a tool to pry embedded fossils from the matrix and a collection bag for your finds (a plastic storage bag will do nicely).

Mineral Wells Fossil Park


The park as it exists today is a result of 20 years of erosion of the old City of Mineral Wells landfill's borrow pit, which was closed in the early 1990s. The erosion of the borrow pit has revealed fossils documenting ancient sea species of crinoids (sea lilies), echinoids (urchins), brachiopods, pelecypods (clams and oysters), bryozoans, corals, trilobites (arthropods), plants and even primitive sharks.  http://www.mineralwellsfossilpark.com/
