Is it a seahorse? A plumbing fixture? What about a really big nail? Sometimes artifacts that are buried in the ocean form special crusts called ‘concretion’ that change their appearance and hide their identity. In this lecture, museum conservator Michelle Crepeau discusses what a concretion is, how it forms, and how conservators break them down to uncover the buried archaeological treasure within.

The program is part of our Maritime Heritage Series, informal lectures held in the museum auditorium and focused on North Carolina’s rich maritime history, coastal environment, and culture. Admission is free, and registration is not required.
