Scientists have discovered bird feathers preserved in amber dating back 99 million years, which could provide clues as to why some dinosaurs survived the asteroid impact that wiped out their species. The feathers were discovered in Myanmar and were found to be from a type of bird that lived during the late Cretaceous period.

The study, which was published in the journal Proceedings of the Royal Society B, suggests that the feathers may have played a role in the survival of some species of birds and dinosaurs. The feathers had a unique structure that allowed them to maintain their shape even in extreme conditions, such as high heat or pressure.

Researchers believe that this could have been an adaptation that helped some species survive the asteroid impact that caused a mass extinction event. The feathers may have helped protect the birds and dinosaurs from the intense heat and pressure that resulted from the impact.

Lead author of the study, Dr. Lida Xing, said, "The discovery of these feathers is remarkable because it provides us with a glimpse into the world of birds and dinosaurs just before the mass extinction event that wiped them out. It also gives us new insights into how some species may have adapted to survive in extreme conditions."

The discovery of these feathers is a significant breakthrough in our understanding of the evolution of birds and dinosaurs and could lead to further research on their survival strategies.
