A number of Calusa artifacts were discovered on Key Marco (an island then adjacent, and since attached, to Marco Island) in 1896 by anthropologist Frank Hamilton Cushing as part of the Pepper-Hearst Expedition. The most notable artifact discovered was the carved wooden "Key Marco Cat", now on display at the Marco Island Historical Museum under a loan from the Smithsonian Institution.
