Enantiornithines are the most diverse avian clade in the Cretaceous. However, morphological specializations indicative of specific ecological roles are not well known for this clade. Here we report on an exquisitely well-preserved specimen from the Lower Cretaceous Jehol Group of northeastern China, which pedal morphology is suggestive of a unique ecological specialization within Enantiornithes...

Although some authorities, such as Florentino Ameghino and William B. Scott, thought that case could be made for regarding Trigonostylops astrapothere, took different position, emphasizing what would now regard...
