A Pile of Questions

[endocrin@desktop.com.au (Graeme Worth)]

Maybe someone out there can help with one or more of these queries?
1) The only species of Daspletosaurus I have listed is D. torosus. Is this
still valid, or is it now a junior synonym of Gorgosaurus libratus?

2) What are the currently accepted valid species of Albertosaurus?

3) Ditto for Parasaurolophus?

4) Ditto for Kritosaurus and Gryposaurus?

5) Are Yangchuanosaurus shangyouensis and Y. magnus valid species or have
they also been transferred to Sinraptor with Y. hepingensis?

6) Does anyone have any info on Edmontosaurus major, or the Nodosaurus
species sternbergi, coeli or landerensis?

7) Are the Oldman and Judith River Formations of Alberta different
formations and how? Does Dinosaur Provincial Park include either or both of
these? I've seen references to various dinosaurs where different authors
give one or the other formation, or just DPP.

8) Is there an updated (from The Dinosauria) concensus on the best
classification of the hadrosaurs?

9) Are there any skulls at all attributed to Hadrosaurus? If not, and if the
skull is essential for hadrosaurid classification (hence the loss of
Hadrosaurus to nomina dubium) why was the first specimen of Kritosaurus or
Gryposaurus not also attributed to Hadrosaurus? If Hadrosaurus is to be
nomina dubium, what do we now call the hadrosauridae and hadrosaurinae?

Thanks in advance for your answers.
