Sixty-eight million years ago, one of Earth's most formidable predators struck an evolutionary bargain that still puzzles science today — surrendering functional arms in exchange for a skull of almost incomprehensible destructive power. A new study from UCL and Cambridge, drawing on data from 82 carnivorous dinosaur species, confirms what the fossil record has long hinted: that the body, constrained by energy, must choose its weapons carefully. The T-Rex chose its jaws, and for millions of years, in a world without rivals, that choice was enough.
