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 current slate of MGS officers was re-elected at the November 2018 meeting: Gary Lohman, President; Eric Seifter, Vice President; Rob King, Treasurer; Marci Robinson, Secretary. Congratulations!!

  • At the November meeting, a motion was approved to rename the annual MGS journalism award to honor Michael Hutchins, a prolific contributor to the club's newsletter The Rostrum. Michael passed away in early 2018. A selection of his newsletter articles can be found here.

  • The highlight of specimens on display at the meeting was the nearly 4" long tooth found by Gary Grimsley along the Potomac River. Pictured below (lingual view on left, labial view on right), this tooth appears to be from a form of the megatoothed shark Carcharocles auriculatus (photographs by Mel Hurd):

  • Among the other items on display or auctioned off were a Pleistocene sand dollar from Aurora, NC, and a small vertebra, possibly crocodilian, found at Purse State Park by junior member Mason (photographs by Jim Stedman):
