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

  • On March 16, 2015, the Maryland House of Delegates' Judiciary Committee unfavorably reported a bill to ban the sale of ivory. MGS President Gary Lohman previously released a statement opposing HB713 because the bill's expansive definition of "ivory" would criminalize the sale of fossil teeth, including shark teeth. Two MGS members testified against the bill before the House Judiciary Committee.

  • Memorial Day Mini-Conference sponsored by the Calvert Marine Museum Fossil Club and the FOSSIL Project will be held May 25-26. Flyer is available here. Fee waiver application for 10 individuals is available here.

  • Fossil and mineral donations needed for the regular MGS auctions.
    Please bring some to the next meeting.



Seen at the March meeting

Timothy Foard gave a fascinating talk titled "The Amateur Paleontologist's Guide to Thin Sections, Part I: Fossils (Mostly)." Shown below are images of thin sections he presented during his talk. On the left is a thin section of a fossil shark tooth; on the right, a thin section of petrified wood (beech, perhaps). These thin sections show the internal structures still present in these fossils.



Winners of the MGS Journalism Awards were announced. In addition, a special MGS President's Award was given to Junior Member David who was one of two MGS members who testified on HB 713 before the Maryland House of Delegates' Judiciary Committee. The award winners who were present at the March meeting are shown below (back row: Rick Smith, Jim Stedman, Bob Farrar; front row: David).



Three whale teeth were on display during the March meeting. Gintas Bichell brought these in from his collection to suggest some of the teeth whose sale would be affected by a bill before the Maryland House of Delegates to ban the sale of ivory. From left to right in the photograph below are a fossil pilot whale tooth, a fossil sperm whale tooth, and a modern sperm whale tooth.
