Saturday, Oct. 16 is the date for this year’s National Fossil Day celebration.

People of all ages are invited to view tables of specimens and information from local and global collectors, share their own fossils with experts from Harvard and Yale, and enjoy a day of earth science education. Jonny Baer will present fossil projections.

The free, annual event will take place at the Tabernacle in Oak Bluffs from 2 to 6 p.m. It will be held outdoors but masks, vaccinations and/or recent negative Covid tests are recommended.

National Fossil Day is a project of the National Parks Service. This year’s event includes participation of the Oak Bluffs Public Library and the Marine and Paleobiological Research Institute, with support from the Martha’s Vineyard Cultural Council.
