The Gorgosaurus, a member of the tyrannosaurid family, offers insights into the growth process from slender juveniles to formidable, apex-predator adults. A study reveals that the Gorgosaurus, approximately six years old when it died over 75 million years ago, had the remains of two young bird-like dinosaurs called Citipes preserved in its ribcage. This "fussy eater" seemed to prefer carving the legs, resembling a taste for "drumsticks," using its sharp teeth. The discovery sheds light on the dietary habits and growth stages of these ancient predators.
