New paper out on the Fransian-Fammenian Extinctions

PPP FFSome of my collaborators and I have a new paper out in the journal Palaeogeography, Palaeoclimatology, Palaeoecology about the role of the development euxinic waters – oxygen deficient and hydrogen sulfide containing – in the Late Devonian extinction events. Click the banner with the title on this post above to go to the journal page.

The Frasnian–Famennian (F–F) extinction event is one of the ‘Big 5’ extinctions: Five of the most severe extinction events in the past 542 million years). We use multiple lines of geochemical data to show that euxinia developed in the Michigan Basin during these extinction events. Based on our data, while the expansion of marine euxinia may not be the sole cause of the Late Devonian extinctions, it appears to be a viable local driver of these extinctions in particular environments.
