according to this write-up of Z rex (which is assumed to be male) at:
The skull shows evidence of a terrible wound in life that re-healed
apparently did not bother the beast. A hole is still seen on the

also appears to be teeth marks in the skull.
thus males AND females got T rex-inflicted ouchies.
