A new online paper:

Skin pathology in the Cretaceous: Evidence for probable failed
predation in a dinosaur.

Examination of preserved skin from a duckbill dinosaur revealed
disruption of the normal scale pattern and replacement by granulation
tissue. Wrinkles radiating outward from the scar document wound
contraction similar to that seen in modern injuries. This is the first
unequivocal report of dinosaur tissue response to dermal pathology and
evidences behavior – escape from a predator.
