At my Big Al page


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


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.
