Summary:
Stegosaurs might be portrayed as lumbering plant eaters, but they were lethal fighters when necessary, according to paleontologists who have uncovered new evidence of a casualty of stegosaurian combat. The evidence is a fatal stab wound in the pubis bone of a predatory allosaur. The wound -- in the conical shape of a stegosaur tail spike -- would have required great dexterity to inflict and shows clear signs of having cut short the allosaur's life.
