Prosaurolophus species INFO!!

[Alessandro <amaris@tin.it>]

Dear ListMembers, please could someone tell me if the new Horner's species
of Prosaurolophus, P. blackfeetensis is still valid or if it's a junior
synonim of P. maximus? I ask this because in his MS.Thesis on the
Hadrosaurian Dinosaurs of the Big Bend
Texas, Dr. Wagner suggested that the two characters used by Horner (1992)
are due to crushing of the type skull of P. blackfeetensis, than to real
difference. And in view of this he concluded that P. blackfeetensis is a
junior synonym of P. maximus. And also, in his monograph on P.
blackfeetensis Horner mentioned the follows specimens: RTMP PC 84.1.1, ROM
4971, and ROM 1928 as pertaining to P.maximus, there're someone that could
tell me the exact material for each specimens? Through all the artist
present on the "DML" and "Dinosauricon" there're someone that have a
skeletal reconstruction of Prosaurolophus based on a different specimen than
that of Paul, which is based on ROM 787.

By and thank's
