Taghanic event

The Taghanic event (Taghanic unconformity, Taghanic crisis and Taghanic onlap) was an extinction event about 386 million years ago during the Givetian faunal stage of the Middle Devonian geologic period in the Paleozoic era. The cause of the extinction event is from an anoxic event and hypoxia. The event had a time span when the dissolved oxygen (O₂) level in the Earth's oceans were depleted. The Taghanic event caused a very high death rate of corals. The loss of the corals reefs, caused a high loss of animals that lived in and around the reefs. The extinction rate had been placed between 28.5 and 36%, making the event the 8th highest extinction event. The reduced oxygen levels were caused by a period of global-warming. The global-warming was caused by the Milankovitch cycles. In the Taghanic event sea levels were higher. After the Taghanic Event, sea life recovered in the Frasnian faunal stage starting 382.7 million years ago. The two other events near this time span were the Kellwasser event (372 ma), and the Hangenberg event (359 ma).
