Enantiornithines, a group of birds, were the only dinosaurs to survive the asteroid strike that wiped out non-avian dinosaurs.

Molting, the shedding and regrowth of feathers, played a significant role in the fate of Enantiornithines.

Feathers are complex structures that cannot be repaired, necessitating the molting process.

The study suggests that ancient birds may not have molted as frequently as modern birds, potentially molting simultaneously or irregularly.

Prehistoric birds and feathered dinosaurs likely had different molting patterns, which may have influenced their survival.

Moult is considered a significant factor in determining which dinosaurs were able to survive the mass extinction event.

The Enantiornithines, a now-extinct precocial group of birds, were unable to cope with the demands of molting during the asteroid impact.
