Spinosaur

["ekaterina amalitzkaya" <eamalitz@hotmail.com>]

I recently recall reading on the web that Suchomimus may be a junior synonym 
of Baryonyx. Are there reasons to seriously believe this. While definitely 
very similar are there no autapomorphies that distinguish Suchomimus. Could 
the theropod experts on the list explain this? Especially given that Sereno 
et al claim that Cristatusaurus from the vicinity could be a synonym of 
Baryonyx suggesting that Suchomimus and Baryonyx could have co-existed-?? a 
strange case of speciation?

Also I would like ask if the experts have reached a consensus regarding the 
synonymy of Angaturama and Irritator. Further one thing puzzles me- in the 
Taquet paper on Cristatusaurus there is claim that Pelicanimimus may be 
related to spinosaurs. While I find this strange is it possible that there 
is some truth to this especially given the presence of teeth in  the beast 
unlike other spinosaurs.
