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

  • At the May meeting, Dr. Bretton Kent of the University of Maryland will be the featured speaker. His talk, titled "The Rise and Fall of the Neogene Giant Sharks," addresses a topic of great interest, particularly for those of us who collect shark teeth along the Calvert Cliffs. Dr. Kent is the author of Fossil Sharks of the Chesapeake Bay Region, one of the most important resources for identifying fossil shark teeth from this area.

  • The FOSSIL Project is seeking input on topics for a series of paleontology-focused online seminars ("webinars"). Please respond to the Project's survey to suggest different topics for these monthly webinars. Responses are requested by May 10, 2016. The FOSSIL Project, based at the Florida Museum of Natural History and supported by the National Science Foundation, is creating a networked community of amateur and professional paleontologists.

  • At the March meeting, geologist Ming Tang gave a talk on his work dating the onset of plate tectonics. He made an exceedingly complex topic both accessible and fascinating. His talk was based on the paper he coauthored titled Archaen Upper Crust Transition From Mafic to Felsic Marks the Onset of Plate Tectonics (Science, January 22, 2016). It can be found here. In the photo below, MGS President Gary Lohman introduces Ming Tang.

  • At the March meeting, MGS Junior Members participating in the Future Rockhounds of America, a program of the American Federation of Mineralogical Societies, received badges. In the photograph below, the proud badge recipients pose with sponsor Rick Smith.

    More information and pictures are available on the MGS Future Rockhounds webpage.
