While I don't have the paper on hand, Aase Jacobsen reviewed several
hundred isolated hadrosaur and ceratopsian bones from DPP, and found
that tooth-marked bone is actually quite common.  Don't remember the
numbers offhand, sorry...

determined by tooth marks on dinosaur bones.  Historical Biology 13:

See:

been a scavenger rather than a predator? An energetics approach.  Proc
