Some Dinosaurs Had Hollow Bones Like Birds
Fossil evidence reveals that many meat-eating dinosaurs possessed lightweight, air-filled bones similar to those of modern birds. These hollow spaces reduced weight while maintaining strength, an adaptation that likely helped with agility and possibly breathing efficiency. The similarity supports the evolutionary link between dinosaurs and birds.
💡 Fun detail:
Some dinosaur bones contained internal struts that look almost identical to those in a chicken wing.
