@ASDFGirl: At least one of these 'many' - I only know of this single one - comments by PCA was from August 2nd, on Adsper's "All Possible Mobs" blog post. It is on the second page of comments. (The one labeled "2", not the one which is second-oldest)

His exact post was:

"Archaeopteryx is not obscure...

Also, the obscure A creature was revealed to be Austroraptor, which I'm not sure if they'll even add anytime soon."

 Any way, hopefully that is helpful. Sorry I can't find any others - I just happened to remember there being one on that blog post. :)
