Largest T. rex specimen died from complications of broken rib, fossil analysis reveals

Tens of millions of years after the last Tyrannosaurus rex walked the earth, science has found a way to read the final chapter of one individual life — not from the shape of its bones alone, but from the preserved tissue within them. The largest T. rex ever discovered, a creature that stood as the apex of its age, was brought low not by a rival or a catastrophe but by the slow, compounding consequences of a broken rib. In learning how this particular animal died, we are reminded that vulnerability is not a condition of the small or the weak — it is the common inheritance of every living thing.
