I have the Wealden ornithopods _I. fittoni_ and _I. dawsoni_ as the earliest 
_Iguanodon_ species.  They both come from the Wadhurst Clay (division of 
Hastings Beds) of East Sussex, England.  I have this dated as Valanginian, 
but I could be wrong on this score.  I find Wealden stratigraphy very 
confusing.

The other _Iguanodon_ species - _I. anglicus_ (?nomen dubium), 
_bernissartensis_ (incl. _orientalis_), _atherfieldensis_, _lakotaensis_ - I 
have as Hauterivian or younger.

Based on Bakker's brief description, this does not look like true 
_Iguanodon_.

Hope that helps.
