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!

Some Highlights of the May Meeting

  • Gene Hartstein gave a well-received talk to the joint MGS and American Fossil Federation meeting about the fossil flora and fauna that has been found at Mazon Creek (Illinois). Located just 54 miles from downtown Chicago, this 300-million-year-old, Pennsylvanian (Late Carboniferous Period) lagerstatte has yielded a wealth of beautifully preserved fossils. These fossils are found inside siderite concretions. The photos below show Gene and a few of his impressive slides depicting various Mazon Creek fossils. A few more photos from the May meeting featuring Mazon Creek fossils in MGS member Mel Hurd's collection can be found on the MGS Gallery page.

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.
