Mass/length estimates

["Jordan Mallon" <j_mallon@hotmail.com>]

Have any mass or length estimates been published for the following 
dinosaurs?
_Pachyrhinosaurus_
_Piveteausaurus_ (I know, this is asking a little much)
_Pyroraptor_.
Not much has been published on _Pyroraptor_, and I know _Piveteausaurus_ 
consists of next-to-nothing, fossil-wise.  But I've been having a hard time 
finding a mass estimate for _Pachyrhinosaurus_, especially.

Thanks,

Jordan Mallon
