Re: sorry - replied wrong: RE: toofs
Karen Moreno's (recently mentioned on list by Jerry) work on the
mechanics of the V. komodoensis skull under simulations of high,
post-cranially generated loads suggest that this behaviour could work
for theropods with an analagous, 'space-frame' construction. In
mechanical terms, the optimisation (i.e strength for unit weight) of the
Komodo skull under these loads is remarkable. Definitely worth testing
to see if similar things are happening with some of the
non-tyrannosaurid species, as has often been suggest (by Bakker and
Rayfield, amongst others).

If Allosaurus and Acrocanthosaurus teeth were sufficient to kill their
sauropods (albeit perhaps with aid of talon-based wounds), why wouldn't the
even-larger Giganotosaurus teeth be sufficient?
The different sized (and more importantly, shaped!) teeth of tyrannosaurids
most likely represents a different in the style of their feeding, not in the
size of the "target audience." Ditto spinosaurid teeth.
