Yes, and further, the point I wished to make is that as far as I know, 
it
is not an "almost" certainty that Velociraptors had fur or feathers.  
Nor
is it REAL simple to know things like that.  If this list fills an
educational role in any way, I think it's wrong to spread speculative 
ideas
as though we really know things that we don't know.  People could 
"learn" a
whole lot of hooey that way.
