The decision to return the remains follows years of campaigning by Inishbofin historian, Marie Coyne

Thirteen skulls were taken from a monastery on the island of Inishbofin off the west coast of Ireland by two Trinity University-affiliated academics in 1890

Marie Coyne, a genealogist who set up the Inishbofin Heritage Museum, said that islanders want the skulls returned and that the process has been too drawn out.

Bird skulls evolved much more slowly and are far less diverse than those of dinosaurs, a new study suggests.
