Prettige feite

Patagopteryx had no wishbone (furcula), so it could not have the muscles needed for flying.1

Its legs had very short thigh bones (femurs), which is a sign it was a fast runner.1

The feet of Patagopteryx had fused bones, just like modern birds.1

It lived about 85 to 83 million years ago, during the Santonian stage of the Late Cretaceous.2

Patagopteryx probably traveled in flocks across the plains of South America.1

Vir dino-kenners

Wetenskaplike naam: Patagopteryx
Benoem deur: Alvarenga and Bonaparte 19923
Groep: Vroeë voëls
Familie / klade: Ornithuromorpha3
Klassifikasie: Theropoda > Avialae3
Ouderdom van die rotse: 86 tot 84 miljoen jaar (Santonian)3
Rotsformasies: Bajo de la Carpa3
Lande: Argentinië3
Fossielrekords: 1 in The Paleobiology Database3
Ontdekking: Oscar de Ferrariis found the first fossils around 1984 to 1985 in Argentina. He gave them to paleontologist José Bonaparte, who named the species Patagopteryx deferrariisi in 1992.1
Steeds omstrede: Scientists are not sure if Patagopteryx is the earliest flightless bird, because some earlier dinosaurs may also have lost the ability to fly.1
