An Irish geologist has discovered a 320-million-year-old shark tooth fossil on the north Clare coastline at Doolin.
Dr Eamon Doyle of the Burren and Cliffs of Moher UNESCO Global Geopark made the discovery of the tooth.
It belongs to a shark that once hunted in the ancient seas of the Carboniferous period in the waters off Ireland at a time when Ireland was located close to the equator.
"Fossil sharks teeth of this age are very rare in Ireland and so it extends the known range of fossil sharks in Ireland," said Dr Doyle.
The fossil will be on public display on 25 May at an event in Ennistymon Public Library as part of the annual Burren Rocks programme.
