The fragmentary remains of a bottlenose dolphin skull were found in the northeast quadrant of the Miami Circle. Reconstruction of the available bones indicates that most of the cranium is present, lacking teeth and lower mandible. Radiocarbon dating of the dolphin skull indicates it was buried sometime around A.D. 1530-1680. Dolphin skulls have been reported from a few other Florida sites and may have been kept in order to extract the numerous, conical teeth, which were used as beads and pendants. At least one example of a perforated bottlenose dolphin tooth was recovered from excavations at the Miami Circle.
