A Guide to Cork City's Geological Heritage

The Ice Age or the Quaternary (starting about 1.2 milion years ago) is not a long time ago compared to the staggering 350 to 380 million years going back to the Devonian and the Carboniferous periods. But the Quaternary landscape of Cork City was still different despite being a few tens of thousands of years ago. We would have had hyenas, reindeer, wolves and bears roaming around in this area as well, while the local sea levels were much lower than they are today.
