I've heard that explanation, but Buffetaut has published arguments to the
contrary - that at least two skulls show a rostral horn. Not sure I buy
it, but here's the reference:
Buffetaut, E., and H. Tong-Buffetaut. 1993. Tsintaosaurus spinorhinus

hadrosaurs (Dinosauria) from the Upper Cretaceous of China. C.R. Acad.
