Latest News

Meeting Held on Thursday, October 14

At the latest MGS meeting (October 14 on Zoom), MGS President Rick Smith led a discussion of the salient issues that should be considered as the club determines where, when, and how to conduct future meetings. Rick said that a November issue of the newsletter would include a survey regarding those issues and that a November Zoom meeting would be held to make relevant decisions.

Also at the meeting, Jim Stedman gave a talk introducing microfossils with a focus on finding foraminifera and ostracode fossil shells in Maryland. The montage of images below shows the various foram and ostracode shells included in his talk. All of these specimens came from matrix inside two fossil mollusk shells found along the Calvert Cliffs. They are from the Miocene.

Evolutionary biologist Keith Thomson:

Fossils give us an extended view of life itself, projecting life into a time dimension in which an anthropocentric viewpoint is meaningless.
