Szechuanosaurus

[pharrinj@PLU.edu]

I apologize for clogging the list with so many posts, but it's interim up 
here and I'm BORED.

I recently read the archived post on the description of the new species 
of _Szechuanosaurus_.  It points out that the taxonomy of this genus is 
rather shaky because it is based on a tooth.

In fact, G.S. Paul points out in _Predatory Dinosaurs of the World_ that 
the _Szechuanosaurus_-type teeth found with the "_S. campi_" skeleton 
weren't even in the jaws but probably represent those of another theropod 
scavenging on the carcass.  If this is the case, there is no reason to 
think that the skeleton belongs to _Szechuanosaurus_ and the skeleton 
should be renamed.  Paul apparently thinks it is _Yangchuanosaurus_, but 
as he--rather oddly--lumps this genus into the poorly-known 
_Metriacanthosaurus_, I can't tell for sure.

Also, has anyone renamed the weird-looking "_Albertosaurus_" yet?  I mean 
the one with the low, rectangular orbital horn, big teeth, shallow jaw, 
and rectangular skull, represented by several good specimens (I don't 
have the designations with me, but if I can get my hands on my copy of 
_PDW_...).  To me it looks less similar to the type of _A. 
libratus_ than does _Daspletosaurus_ or _Dinotyrannus_, so it needs a new 
generic title (and certainly a new trivial name; no way is it _A. libratus_).

I suggest _Albertogorgon lambei_, but as I have no Ph.D., no one has to 
listen to me.  "_Gorgosaurus" sternbergi_ also belongs in this genus.

As always, comments are encouraged
