Only to the ignorant. Teeth and jaw fragments can tell a knowledgeable person a lot about the owner of that tooth or jaw fragment. Dentition can be signature features in identifying evolutionary relationships because certain dental features and certain combinations of features arise and are preserved in some lineages and not in others.
Further, by examining the surrounding structures, the combinations of teeth, their placement, etc., knowledgeable people can learn a lot about the behaviors and diet of these creatures, because certain features are consistent across lineages, depending on these dietary or behavioral factors.
You guys really excel at attempting to make those who disagree with you look stupid. I'm ignorant - oh, well. By the way, that isn't going to win you any converts.
