    5 farklı kaynaktan alınan bilgiyle göre

    Geç Devoniyen yok oluşu, yaklaşık 375 milyon yıl önce gerçekleşen ve deniz canlılarının büyük ölçüde yok olduğu kitlesel bir olaydır. Volkanik aktiviteler ve okyanuslardaki oksijen tükenmesi (anoksi) bu yok oluşun başlıca nedenleri arasında gösterilir.123

    Yok oluş, özellikle denizel yaşamı derinden etkilemiş ve türlerin önemli bir kısmı kaybolmuştur. Bu süreç, uzun süreli volkanik patlamalar ve iklim değişiklikleri ile ilişkilendirilir.24

    Geç Devoniyen, aynı zamanda karasal yaşamın evriminde kritik bir dönem olarak kabul edilir. Ancak yok oluş hızı ve nedenleri tam olarak anlaşılamamıştır.35
