<< I don't think this would happen, for two reasons:
 1) As with centrosaurines and chasmosaurines, the diagnostic characters of 
 lambeosaurines are probably ontogeny-dependent and only manifest themselves 
 with maturity.  _Procheneosaurus praeceps_ may be a juvenile _L. lambei_, 
 but this this will be hard to prove.  Like _Monoclonius crassus_ and 
 _Brachyceratops montanensis_, names based on juvenile lambeosaurine material 
 are probably best treated as nomina dubia.
 (2) Any attempt to sink _L_ into _P_ would be met with some degree of 
 consternation from the palaeontological community.  I'm sure the ICZN would 
 be petitioned to have a name as well-loved as _Lambeosaurus_ preserved and 
 _Procheneosaurus_ suppressed a la _Coelophysis_. >>

I certainly agree. But the possibility does exist.
