In-Person Meeting and Auction Held on Sunday, October 22nd

The Maryland Geological Society held an in-person meeting on Sunday, October 22nd, during which the current slate of officers was returned to office as were most board members (one vacancy was filled). The highlight of the meeting was the club's annual auction. Many excellent items triggered several rounds of spirited bidding. A key ingredient to this successful event was the work of MGS VP Eric Seifter who served as auctioneer. The montage below captures some of the action and items.

Stories of Exciting Finds Along the Calvert Cliffs

Two amazing, recent fossil finds along the Calvert Cliffs should excite all MGS fossil collectors. Both discoveres were made by volunteers with the Calvert Marine Museum. The first is a 12-million-year-old gannet skeleton, the most complete bird skeleton ever found along the Cliffs (link). The second is that of a wonderfully complete skull of a 15-million-year-old dolphin ancestor (link). Check out these and other stories on the MGS WebSightings page.
