## Curiosity - Did you know?

For over a century, paleontologists debated whether *Archaeopteryx* actively flapped its wings or merely glided from high branches. In 2018, scientists utilized **synchrotron X-ray microtomography** on its long bones and finally solved the enigma.



The scans revealed that the bone walls of its arms possessed a thickness and torsional resistance matching modern birds capable of active **burst flight** over short distances, much like today's pheasants. Lacking the complex shoulder joint of modern birds, its wing strokes must have looked incredibly peculiar. While it lacked efficient, long-distance flight capabilities, it generated more than enough power to escape ground predators or leap agilely from branch to branch!
