BTW -- Sharks are the best extant velociraptor
'tooth-analogue' I know of. Are there any other
candidates?
Shark teeth are not all that similar. They are straight, they are replaced
extremely quickly on a conveyor-belt system, and even the serrations aren't
the same shape AFAIK. Monitors come a lot closer, but "velociraptorine"
teeth are much more strongly inclined backwards. It appears the bite
strength was not great (Jurassic Park the book notwithstanding <sigh>).
