Naughty plants. 

Poor fishies. 

Very interesting idea.

I see the plant hypothesis is still alive - or news just takes a long time to reach Alaska.  Algeo and others have been positing this as a contributing cause since the 1990s. See, for example:

 

Algeo, T.J., R.A. Berner, J.P. Maynard, and S.E. Scheckler. 1995. "Late Devonian oceanic anoxic events and biotic crises: "Rooted" in the evolution of vascular land plants?" GSA Today 5: 45, 64-66.

Algeo, T.J. and S.E. Scheckler. 1998. "Terrestrial-marine teleconnections in the Devonian: links between the evolution of land plants, weathering processes, and marine anoxic events." Phil. Trans. R. Soc. Lond. B 353: 113-130.

Of course, the Devonian had at least five major extinction events, with a cluster of smaller ones.

In 2013 I wasn't yet interested in fossils (let alone the 90s ), so for me it is something new - I hope true experts on the subject will excuse the zeal of the novice ....

A good hypothesis never goes out of date.

I gather the Chattanooga/'Kinderhook' Shale of the interior USA is representative of this event.
