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 joint meeting with the American Fossil Federation, Dr. Bretton Kent of the University of Maryland spoke on "The Rise and Fall of the Neogene Giant Sharks." In a rich and fascinating talk, Dr. Kent described how rising temperatures, beginning in the Late Oligocene, marked a period of great diversity and expansion of marine communities, fueling the rise of giant shark species. He focused principally on the False Mako Shark (Paratodus benedeni) and Giant Thresher Shark (Alopias spp.). Dr. Kent is seen below (on left) engaging MGS/AFF member Mark Bennett in a discussion of the finer points of these sharks.

  • Up for auction at the May meeting were some choice fossils and minerals, including the specimens seen below: a fierce Eocene crab, Xanthopis dufouri, from Spain and a beautiful Ecphora from Lee Creek, NC.
