After some searching, I found this:
Predatory Fish Once Prowled Ancient Canadian Arctic
A species of fish previously thought to have only existed in Eastern Europe once prowled ancient North American waterways during the Devonian Period, before backboned animals existed on land. [my emphasis]
I just can't think of a comment fit to publish even on a blog. *Sigh!*
