Naam beteken: “grasping bird”1

Rapaxavis was a tiny bird that lived during the time of the dinosaurs. It had a long, curved beak and special feet that could grab onto branches like a modern parrot.2

Prettige feite

Rapaxavis had teeth only in the front of its upper and lower jaws, unlike many other birds.2

Its feet were perfectly adapted for grasping branches, making it one of the first birds known to be strongly arboreal (tree-living).2

The fossil of Rapaxavis was so well preserved that scientists could see the keratin sheaths on its toe claws.2

Rapaxavis lived about 113 million years ago, during the Early Cretaceous period.1

The holotype (main specimen) was a subadult, meaning it was not fully grown when it died.1

Its name comes from the Latin word 'rapax' meaning grasping, because of its strong feet.1

Vir dino-kenners

Wetenskaplike naam: Rapaxavis
Benoem deur: Morschhauser et al. 20093
Groep: Vroeë voëls
Familie / klade: Longipterygidae3
Klassifikasie: Theropoda > Avialae3
Ouderdom van die rotse: 121 tot 113 miljoen jaar (Aptian)3
Rotsformasies: Jiufotang3
Lande: China3
Fossielrekords: 1 in The Paleobiology Database3
Ontdekking: Rapaxavis was named in 2009 by Eric Morschhauser and colleagues. The fossil was found by Pan Lijun at Xiaioyugou, China, and was first thought to be a different bird called Longirostravis.1
Steeds omstrede: Scientists are not sure if Rapaxavis was fully grown when it died, because its bones were not completely fused.2
