The Maryland Geological Society is a non-profit organization dedicated to the collection, study, and display of all aspects of the geological sciences. Members include amateur and professional fossil and mineral collectors. Membership is open to all.

The club meets at the Community Center in Bowie, Maryland, on the third Sunday of every other month, beginning in January. Visitors are welcome!

What's Hot

  • The 16th Annual MGS Auction will be held on Sunday, September 16, following the business portion of the regular meeting. This fun event helps fund the club and is the primary reason the annual dues are so low. MGS members are invited to submit fossils, minerals, archaeological artifacts, and meteorites to the auction. Complete information and necessary forms can be found here.

    Visitors are welcome to come and bid on the items up for auction which, each year, have included some incredible objects.

  • The August 2018 issue of Rock & Gem Magazine features an article by MGS member Bob Farrar. Titled Moroccan Aragonite: Specimens by the Millions, it highlights a trip Bob took to Morocco in October, 2017, to a premier source of aragonite.

Among the objects members displayed at the July meeting were:

A very fine collection of shark teeth brought in by new Junior MGS member Mason who found these at Brownies Beach:

MGS Members Contribute to Calvert Marine Museum's Dinosaurs of Maryland Exhibit

The Calvert Marine Museum opened a new exhibit on April 6 titled "Dinosaurs of Maryland" which features, among other fossils, several on loan from MGS members Mike Folmer and Rick Smith. MGS member Flo Strean provided important financial support for this exhibit. The exhibit is on the Mezzanine Level of the museum and runs through the end of 2018.


Our Changing Planet in Deep Time

Software engineer Ian Webster has created a fascinating, interactive 3-D tool to explore not only how the Earth's tectonic plates changed over deep time, but what happened in specific locations (for example, where you live). Webster's creation is the subject of a recent article on the IFLScience website. It's quite a trip into the past.
