"A cool, clean, clear stream babbling over limestone and close to home, unheard of, right? Well, just a few dozen miles north of Fort Worth, a bit northwest of Justin is Oliver Creek. A while back we tracked a creek full of tumbled fossils upstream to their source and the gracious landowners consented, once again, to let us tromp up and down their lovely creek. Not only is it a neat place for a pastoral outing and picnic, but the soft limestone yields ammonites like Oxytropidoceras (you will be required to say this) and echinoids (sea urchins) like Epiaster whitei, Heteraster texanus and the rarer, Phymosoma texanum and Salenia mexicana and a few shark teeth. Seams of soft marl hold echinoids ideal for mining. So, you WILL find ammonites and you WILL find echinoids as well as the rest of the typical marine fauna like crab parts, gastropods (snails) and pelecypods (bivalves).

We’ll be collecting on very private land in the Goodland Formation (Lower Cretaceous, middle Albian) just west of Drop, Texas (don’t look for skyscrapers here). This is a fairly large, open creek bed so many people can collect. Perfect for kids – they will find neat stuff - and pets. Just mind your invitees. We are out in nature, so expect the normal fare of bugs and other creepy crawlers. Hopefully we’ll have water in the creek this year so kids can splash or do tadpoles and crawdads." DPS
