MGS Mourns Passing of Longtime Member Flo Strean

Florence "Flo" Jones Strean passed away January 19, 2022. Flo, a committed collector of fossils, minerals, and shells, was a stalwart member of the MGS. She rarely missed a meeting and she typically had an array of recent finds on display. Flo was eager to learn and generous with her knowledge. She also was extremely generous with her financial support of the Calvert Marine Museum's Dinosaurs of Maryland exhibit in 2018. Flo will be missed.

New research suggest that for the most widespread species the full saber tooth was not on display until the animal attacked. Read about this research here. Links to this and many other articles, reports, and blog postings highlighting recent fossil and mineral news can be found on the MGS WebSightings page. Please check it out.
