Ученые впервые исследуют перья, сохранившиеся в янтаре с середины мелового периода. Они мало изменились со времени расцвета динозавров.

До сих пор перья мелового периода – от 66 до 145 млн лет назад – удавалось изучать лишь по скупым источникам. Как правило, свидетельства того времени – это плоские отпечатки в осадочных породах или фрагменты перьев.
