I had the chance to see the Sue cast in Los Angeles, at the LA Natural 
History Museum, and had a couple questions regarding it, and another 
specimen at the museum.
Sue: The knee of the right leg seemed oddly-placed. The femur seemed to be 
touching one of the ribs. This doesn't seem to be quite possible. It would 
have to be projecting through part of the body cavity to get to the position 
it was displayed in. Is this just a fluke in the LA mount, or is this the 
way it's supposed to be.
Other specimen: In the main lobby area, there is a mount of a _T. rex_ 
attacking a _Triceratops_. There was some discussion on the list about how 
there was no side to side flexibility in dinosaurian ankles and knees, and 
the flexibility of the pelvic-femoral joint. The question that came to my 
mind, after seeing this specimen is: How coudl dinosaurs change directions 
if none of there limb joints could move lateraly? This mount appeared to 
have gotten around this by slightly dislocating the left knee of the 
_Tyrannosaurus_. Thanks!
Peace,
