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!

In Memoriam

It is with great sadness that we note the recent passing of Richard ("Dick") W. Grier, Sr. at the age of 97. In 1991, Dick, Sr. was one of the founding members of the Maryland Geological Society and, for many years, worked tirelessly to build and sustain the club. He joined his sons Dick, Jr., and Bob (who predeceased him) in vigorously promoting the paleontological and geological sciences.

The MGS memories of Dick, Sr. are many and cherished whether of him as father, collector, club officer, auctioneer at the MGS annual auction, or passionate advocate for the club. He will be sorely missed.

What's Hot

  • MGS Future Rockhounds of America visit the National Museum of Natural History. In March, the FRA junior members and their families enjoyed a behind-the-scenes tour of the paleontological holdings at the Smithsonian's National Museum of Natural History. Paleontologist Dave Bohaska graciously guided the group. He and FRA members and parents are shown in the photos below, along with a T. rex tooth, one of the many treasures seen during the tour. Many more photos from this event can be found in a montage on the FRA page.

Some Highlights of the March Meeting

  • Junior members David and Brooke described the highlights of their tour at the Smithsonian's National Museum of Natural History. With an introduction from Rick Smith, David also spoke about chromite, his choice for Maryland's state mineral.

    MGS Vice President Eric Seifter made a presentation on Silurian eurypterids from New York highlighted by many high quality specimens. Pictured below (on the right) is a Eurypterus remipes.
