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.
