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

  • Input from MGS members needed! A fossil hunting trip to Stratford Hall, Virginia, during Easter weekend (April 20-21, 2019) is being planned by the Calvert Marine Museum Fossil Club. The specific day in that weekend for the trip has not yet been determined. MGS members are invited to participate in this trip to a great site, but must indicate their interest ASAP by email to , MGS Membership Chair. The per person fee for gaining access to this site depends upon the total number of participants. A document with more information on the location and fees is available here.

  • 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):

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.
