摘要

ABSTRACT The Early Cretaceous (～131?Million Years Ago) Protopteryx fengningensis is one of the oldest and most primitive enantiornithine birds; however, knowledge of its anatomy has largely been limited to the succinct description of two specimens (holotype and paratype). This study describes two new specimens of P. fengningensis preserving most of the skeleton and plumage, and it therefore adds significantly to understanding the morphology of this important species and the character evolution of enantiornithine birds. The well‐preserved plumage of these specimens also affords a quantitative assessment of the flight performance of P. fengningensis . Our aerodynamic considerations indicate that this early enantiornithine was capable of intermittent flight (bounding or flap‐gliding), thus marking the earliest occurrence of such energy‐saving aerial strategy.

Fengningensis的两种新标本，因此可以显着增加了理解这种重要物种的形态和肾上腺鸟类的性格演变。 这些标本的保存完好的羽毛还可定量评估P. Fengningensis的飞行性能。 我们的空气动力学考虑表明，这种早期的肾上腺素能够间歇飞行（边界或翼展滑动），从而标志着这种节能空中战略的最早发生。 ANAT REC，303：716-731,2020。 2019年美国解剖学协会
