Indeed.
My website, in fact, has long featured an essay on this very
topic -- namely, what non-ornithothoracean dinosaurs were and were not
feathered, based on what we know and what we can infer. The essay is
continually updated, although I have not yet had a chance to add information on
the latest Liaoning deinonychosaur (rest assured, I will soon).
The essay can be seen at http://www.cyberus.ca/~sharding/grant/essay/feather.htm.
In fact, it would be really nice if everyone who's interested would read it and
let me know if it's missing any vital information or has got anything
wrong...
Thanks a lot. Peace,
-Grant
