Yuanchuavis kompsosoura

† Yuanchuavis kompsosoura is an Early Cretaceous enantiornithine bird from the Jiufotang Formation of China, remarkable for its ornate ribbon-like tail feathers with elaborate vane structures. These display feathers shed light on sexual selection in Mesozoic birds.

Diet & Feeding

Carnivore

Yuanchuavis kompsosoura was a meat-eating predator. Carnivorous dinosaurs were active hunters or scavengers, equipped with sharp teeth and claws for catching and consuming prey. They occupied the top of the food chain in their ecosystems.

Time Period

Cretaceous Early Mesozoic Era

Yuanchuavis kompsosoura lived during the Cretaceous Early period of the Mesozoic Era, approximately 145,0 to 100,5 million years ago.

The Cretaceous saw continued dinosaur evolution with the rise of ornithopods and early ceratopsians. Flowering plants first appeared and began to transform terrestrial ecosystems. Spinosaurus and other large theropods lived during this time.
