The extinction was caused by climate change. The main cause of extinction was the vast amount of carbon dioxide emitted by volcanic eruptions that created the Siberian Traps, which elevated global temperatures and acidified the oceans.

Dunluce Castle is a now-ruined medieval castle in Northern Ireland, the seat of Clan MacDonnell. It is located on the edge of a basalt outcropping in County Antrim (between Portballintrae and Portrush), and is accessible via a bridge connecting it to the mainland. The castle is surrounded by extremely steep drops on either side, which may have been an important factor to the early Christians and Vikings who were drawn to this place where an early Irish fort once stood.
