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

  • Ever wondered about the reddish-brown color that the fossil shells of the Calvert Cliff's Miocene gastropod Ecphora retain after millions of years? Check out a recent article in Carnegie Science. As MGS member Mel Hurd commented on this research, "Just when you thought we knew all about the Ecphora." The full technical paper can be found in Geochemical Perspectives Letters.

  • Annual auction of the American Fossil Federation will be held on Sunday, March 8. AFF meeting begins at noon at the Bowie Community Center.

  • 2015 dues are due. For more info, go to the Join Page.

  • Fossil and mineral donations needed for the regular MGS auctions.
    Please bring some to the next meeting.



Seen at the January meeting

Among the many spectacular fossils and minerals on display at the January meeting was a selection of Pleistocene fossils brought up from the Continental Shelf, 20 miles off Cape May, New Jersey. This material comes from Bob Asreen's collection. Seen here is part of the jaw of a giant beaver, Castoroides ohioensis.


Additional photographs of this selection of fossils can be seen in the MGS Gallery page.



Fossil Shark Teeth Go To School With MGS Connections

K-12 students across the country, with the support of scientist Bretton Kent and undergraduates at the University of Maryland, are engaged in the SharkFinder project, a citizen-scientist effort to collect and identify fossil shark teeth in matrix samples collected from the Calvert Formation in Maryland and Virginia. The project is operated in partnership with Paleo Quest, a non-profit organization focused on, among other activities, promoting citizen-scientists projects, increasing museums' collections of fossil specimens from the Atlantic Coastal Plain, and studying Coastal Plain stratigraphy. The SharkFinder project is described in a recent article appearing in the University of Maryland's Odyssey magazine.

The MGS connections? David, an MGS junior member, is an active participant in SharkFinder and is featured prominently in the Odyssey magazine article (way to go, David!!). MGS member Dr. Robert Weems serves as Paleo Quest's Director of Stratigraphy and Paleontology.

Highlights of 2014 WebSightings

The paleontological and geological landscape is ever-changing, and keeping up is challenge. The MGS WebSightings Page, which can be found under the Links&Articles Tab above, provides links to some of the more important and interesting stories that were published. To give a flavor of what is highlighted on that page, here are five of those 2014 stories:
