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 American Fossil Federation's annual auction will be held on Sunday, March 12, at the Bowie Community Center (directions here). Doors open at 11:30 am, business meeting of AFF begins at 12 pm, auction begins at 12:30 pm. All are welcome and admission is free. A variety of fossils and fossil-related material will be auctioned off. All sales are cash only. For more information, contact AFF president .

  • The U.S. National Oceanic and Atmospheric Administration (NOAA) issued proposed regulations on January 9, 2017, for creation of the Mallows Bay - Potomac River National Marine Sanctuary, which will encompass the shoreline of Purse State Park and other fossil collecting sites on the Potomac River. Comments on these proposed regulations must be submitted by March 31, 2017. Background information on the proposed regulations and the impact of designating this area as a National Marine Sanctuary can be found on the Federal Register website, the NOAA website, and the Maryland Historical Trust website. According to a Maryland Historical Trust fact sheet, fossil collecting along the shoreline will be permitted as before. The proposed regulations themselves do not specifically state that.

Some Highlights of the January Meeting

  • MGS president Gary Lohman and vice president Eric Seifter gave informal talks (both seen in first picture below). Gary discussed radioactive minerals which he demonstrated with a Geiger counter. Eric spoke about the Sikhote-Alin meteorite which fell in southeastern Russia in 1947 (fragments of the meteorite are shown in the second picture). He also discussed three large ammonites (the third picture shows Perisphinctes sp. from the Jurassic Period).

Recent Finds and Prized Specimens

Many fossil and mineral treasures are on display in the MGS Gallery. The cow shark teeth shown below, Notorynchus primigenius, are part of Jim Stedman's collection. They were found in the Calvert Formation and date from the Miocene Epoch.
