I heard some discussion of T-Rex short arms being used as a means to hold on 
during mating. According to Horner, the arms were short but strong, able to 
lift 400 lbs. Speaking of T-Rex sex, Peter Larson has some interesting 
research in progress regarding sexual dimorphism in T-Rex. He suggests the 
more robust of the specimens are female due to the wider sacral regeon and 
the size, and iI think angulation of the first cheveron of the tail. Perhaps 
some of you have updates on his research. He discussed this at Dinofest in 
Indy back in March.
