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?
