Re: Ornithischian with complex feather-like structures found in Siberia (SVP abstract)

I was looking forward to this as well.  I believe it was cancelled because 
Pascal was in the hospital ( non-life threatening ).   I likened the experience 
to having the stars show up on the red carpet but the movie is cancelled.

  Is there anything formal on this?
