What, no stega?

It may take a particular kind of person to apreciate this, but I think that a new Devonian sarcopterigian fish is actually kind of cute, if not adorable by fossil fish standards1. Perhaps most important is that it isn't a dark grey smear on a dull grey rock (or affectionately known as a Smudgeichthys).
It's a great specimen, but I do have a problem with the name that it was givin. The name is perfectly valid, it just won't make things any easier for students of paleontology. The creatures that students typically memorize as transitional between fish and amphibians are Eusthenopteron, Ventostega, Acanthostega and Ichthyostega. The new fish has been dubbed Tiktaalik roseae. Tiktaalik is from the Inuit word for a large freshwater fish and roseae refers to someone who fronted the money for the expedition to Ellesmere Island.

1. Fleshed out, the creature was probably much more fearsome and ugly than cute and it likely tasted like shark meat.
