Yes, in your opinion.... Almost nothing is known of _Bactrosaurus_' skull,
which is really what is diagnostic about lambeosaurs past deciding if they
are lambeosaurs or hadrosaurs. _Tsintaosaurus_ on the other hand has a
fairly good skull, and associated postcrania.

This only really works on the small scale, like telling the difference
between _Hypacrosaurus stebingeri_ and _H. altispinus_. Remember these
things were used for making the animals look sexy, so it is probable that two
closely related groups had strikingly different crest shapes. Something that
I think is rather interesting is the possibility that _Parasaurolophus_ and
_Lambeosaurus_ are closely related, as they both share a greatly reduced
external nasal bone, compared to the giant nasal in _Corithosaurus_ and
_Hypacrosaurus_, which might represent the plesiomorphic state for advanced

In my opinion also, there should be a lambeosaur family that is seperate from
the hadrosaur family. I also think (I know, me, the heretic) that
_Hadrosaurus_ itself should be made a _nomen dubium_ and the hadrosaur family
should be renamed Edmontosauridae.
One more thing, _Lambeosaurus_ should be said "LAM-o-saurus" since Lawrence
Lambe almost certainly said his name like "LAM" and not "LAM-bee". This
extends to Lambeosauridae - "LAM-o-saur-i-die", and lambeosaur -
