"Iguanodont" Queries

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

Yes, in another unusual post, I again ask some questions about 
ornithischians.  This should thrill and delight those on the list who are 
fascinated with these creatures who are often neglected on the D.M.L.

1.  What are the citations for Iguanodon(?) lakotensis, Iguandon(?) hoggi?

2.  What is the Garden of the Gods Iguanodontid?  It is mentioned in this 
post to the D.M.L.- http://www.cmnh.org/dinoarch/2001Jul/msg00145.html

3.  Is Iguanodon(?) orientalis synonymous with Altirhinus?

4.  Rozhedestvensky 1965 notes that juvenile Bactrosaurus johnstoni have 
only two replacement tooth rows in each alveoli of the lateral teeth (which 
he says is similar to "iguanodontids"), and he notes that adult B. johnstoni 
have three replacement tooth rows in each alveoli of the lateral teeth like 
hadrosaurids.  According to the figures in Norman 2002, hadrosaurids appear 
to have four replacement tooth rows.  Is the increase in the number of tooth 
rows similar or was Rozhedestvensky mistaken in how many he thought were 
present?  And is this character variable between ontogenetic stages, or are 
the juvenile B. johnstoni separate species?
