False teeth sprouted oyster

The Strand magazine, 1903 (public domain)

This set of false teeth gained notoriety when it sprouted an oyster. The oyster-teeth were found inside of the Chesapeake Bay in 1898. They were then proudly exhibited in the Smithsonian, and became a hit (to a fault). Within the following decades, multiple people insisted on ownership over the oyster-teeth. Perhaps these people had all lost dentures in the Chesapeake Bay, or maybe they just felt a burning desire to get their hands on the strange object. Regardless, the Smithsonian didn't surrender the beloved oyster-teeth.
