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

    Of particular interest to fossil collectors in this area, a new research article traces the evolution from Carcharocles chubutensis to Carcharocles megalodon during the Miocene Epoch at the Calvert Cliffs (MD). Victor J. Perez and his coauthors studied the presence and disappearance over time of cusplets on teeth from these ancient sharks. This article appears in the Journal of Vertebrate Paleontology and full text is available here.
