At my Big Al page
http://w3.uwyo.edu/~rtravsky/big_al.html
you can see some pics of an Allosaurus that has 14 skeletal injuries. Two
of the pics show injuries.
This specimen was a juvenile. I don't know what it's age at death was, nor
its age for any of the injuries.
It apparently recovered from all of them. This one critter is a lab in
itself for this consideration.
This page
http://museum.montana.edu/www/paleocat/beccabigal/bigal.html
has more complete info as well as better pics of some of the injuries.
As for other examples of dino injuries, that would be an interesting list.
