As you explain elsewhere, you believe when I said "well-known", I was
refering to some sort of dinosaur popularity contenst. For your future
understanding, "well-known" in the context of fossils almost always means
"represented by better, more complete fossil material".
However, even under the "popularity contest" concept, I counter your
argument that Bactrosaurus is better known among non-scientists than is
Tsitaosaurus. Whereas Bactrosaurus is extraordinarily boring as far as
hadrosaurids go (at least in terms of interesting features), Tsintaosaurus
(with its distinctive vertical crest) has been featured on stamps, covers to
dinosaur books, and most pictures that show hadrosaurid skull diversity. I
certainly knew about Tsintaosaurus before I knew of Bactrosaurus.
As for the supposed composite nature of the beast, recent work by French
paleontologists in China (I can't recall if it is Taquet or Buffetaut, and
incidentally the other disagrees with the first...) have found multiple
partial skulls of Tsintaosaurus, including additional specimens with the
vertical crest. It does seem to be distinctive, a lambeosaurine, and an

Son, before you going around berating the League, let's see if you know what
you're talking about:
List the members of the Ivy League. For extra credit, list the Seven Sisters.

Given that you know very little about biological taxonomy (i.e., if you
don't think crest shape has already been used in the classification of the
lambeosaurines, why do you think they are already named as different genera?
Oh, wait, you probably think they actually HAVE those names, and that they
weren't given them by humans...), I'll let the last few phrases in that
I can challenge your assertion that Ivy League paleontologists don't know
our butts from holes in the ground, but choose not to do so publically in
consideration of the younger members of the reading audience... :-)

Actually, to put us Ivy League paleontologists in our place, let's hear how
you would recognize a lambeosaurine from a hadrosaurine if you didn't find
the skull. (Oh, but that would NEVER happen... ;-)
