The remains of a porpoise were found buried on the island in 2017, during an archaeological dig to look for a religious building, which was thought to have been built on the island in the late medieval period. The porpoise was buried between 1416 and 1490, according to radiocarbon dating and it is thought that it may have been buried to preserve it for consumption as food at a later date.
The skeleton of a Royal Navy sailor was discovered during another archaeological dig in 2018. It is thought that he died around 1760.
