Iguanodont queries

["Nick Gardner" <ratites637@hotmail.com>]

I would appreciate assistance with these queries, even though they are not 
necessarily the normal for this group.



1.  In the original description of _Draconyx_, O. Mateus and M. Antunes 
unite it with the Camptosauridae on the basis of two characters, 1) 
maxillary teeth with strong vertical primary ridge on the distal side of the 
labial crown and 2) femur curved with prominent lesser trochanter.  Is the 
first character a more well-developed version of the primary ridge developed 
in more basal taxa or is it a different structure entirely?  Does anyone 
have any pictures of the teeth and femur of _Camptosaurus_ and other 
camptosaurids for comparison that they could send me?  I would be very 
appreciative.

2.   Though I recognize that _Bactrosaurus_ is now considered more basal, 
what characters were originally used to unite with the Lambeosaurines and 
are they invalid or valid?

3.    Does anyone have any pictures of the material for _Mandschurosaurus_?  
If you know the original citation, it would be helpful if you posted it too, 
and I can try track it down over the summer.  And... uhm... what is 
_Mandschurosaurus_?

4.  Is _Tanius_ still a valid taxon? If so, what is it?  Can someone post 
the original citation?



Thanks in advance
