A 320-million-year-old shark tooth fossil has been discovered12.05.2017
A 320-million-year-old shark tooth fossil has been discovered on the Geopark coastline and will be put on public display next week.
The very rare and significant find was made Dr. Eamon Doyle a geologist with the Burren & Cliffs of Moher UNESCO Global Geopark.
Dr Doyle discovered the tooth which belonged to a shark that once hunted during the Carboniferous period in the waters off Ireland at a time when the country was located close to the equator.
Dr Eamon Doyle said: “Fossil sharks teeth of this age are very rare in Ireland and so it extends the known range of fossil sharks in Ireland. Equally significant is the information it gives us about the biodiversity of these ancient seas.”
“This shark tooth tells us that apex predators of up to 70cm were living here at the time. It is possible they were feeding on creatures known as nautiloids which are spiral-shelled creatures which grew to about 10cm where the tooth was found. These nautiloids were also predators and prior to this find would have been regarded as the apex predator. It is hoped that further finds will add more information,” he added.
