What caused the holes in SUE the T. rex's jaw?

[Still Waters]

SUE the T. rex is one of the most complete, best-preserved Tyrannosaurus rex specimens ever found. That level of preservation helps reveal details about SUE's life. For instance, SUE lived to a ripe old age of about thirty-three, and in those years, suffered their fair share of injuries. SUE's most mysterious ailment might be the holes in their jawbone.

These holes, some the diameter of a golf ball, dot the back half of the left lower jaw. It's not clear what caused them, but similar injuries have been found in other T. rex fossils. In a new study published in Cretaceous Research, scientists showed that one of the popular theories—that SUE had suffered an infection from a protozoan parasite—couldn't be true.

Is golf ball sized also adult T  Rex tooth size?

Good call, Tatetopa.

 

I suspect mating bites by males.
