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

  • Anyone collecting fossils from the Calvert Cliffs will want to secure a copy of The Geology and Vertebrate Paleontology of the Calvert Cliffs, Maryland, edited by Stephen J. Godfrey. It offers detailed descriptions and stunning pictures of vertebrate fossils from the Cliffs. A PDF copy of the book, very recently published by the Smithsonian, can be downloaded here.

  • The 16th Annual MGS Auction, held on Sunday, September 16, was a great deal of fun with some spirited bidding on various attractive and sometimes rare specimens of animal and plant fossils, minerals, artifacts, equipment, and books. MGS Vice President Eric Seifter (seen below) ably served as auctioneer.



    Among other items auctioned off were the following spectacular items: a mastodon tooth, a Cretaceous fish tail and vertebrae, and an Otodus shark tooth in matrix. Each of these is seen below.







    A montage of pictures from the auction appears on the MGS Gallery Page.



  • Rick Smith, editor of the MGS newsletter The Rostrum, was recently inducted into the American Federation of Mineralogical Societies' Bulletin Editors Hall of Fame. Kudos, Rick.

Notable Quote

Evolutionary biologist Keith Thomson:

Fossils give us an extended view of life itself, projecting life into a time dimension in which an anthropocentric viewpoint is meaningless.
