The same-scale graph shows a fossil sample containing an impeccably preserved bird's wing tip and an enantiornithes bird simulation diagram. The tiny specimens of baby birds' wings entombed in amber were found in the Hukawng Valley in northern Myanmar and described in the journal "Nature Communications." This is the first time that wings have been found encased in amber. The samples contain two impeccably preserved wing tips with all features intact, including soft tissue, from two birds that scientists believe were hatched nearly 100 million years ago during the Cretaceous period, about 45 million years after the first birds or avian dinosaurs evolved.
