I have just read in JVP 18/#4/98 the new specimen of Bactrosaurus johnsoni did not have a supraorbital crest. Supposedly, it was a wrong interpretation by Weishampel and Horner (1986). Any chances it might be another species? Dimorphism? Anything else?
If anybody on the list has a new paper on Bactrosaurus, I'd appreciate e-mailed head reconstruction.
