Ten tenths

It is another day of complete cloud cover so my chances of seeing the comet today don't look good. To compensate I have been doing a more thorough than usual look around the science news sites.

So, a question for the science nerds. Which is more exciting:
A feathered dinosaur that may have flown like a biplane.
A walking molecule which can carry a load.

Your answer may reveal something about yourself. Personally, I'm going with "both are cool".
