Parahongshanornis

Naam beteken: “near Hongshanornis, named for its close relationship to that bird”1

Parahongshanornis was a tiny, feathered bird that lived about 120 million years ago in what is now China. It could probably fly, but its legs were longer than its wings, so it might have spent a lot of time running or wading.1 2

Prettige feite

Parahongshanornis had a U-shaped furcula (wishbone) that was much longer than it was wide, which is a special feature of its family.2

Its legs were longer than its wings, which is unusual for a bird and suggests it was a good runner or wader.2

The fossil includes soft parts like feathers, even though the skull is missing.1

It lived about 120 million years ago, during the Aptian stage of the Early Cretaceous.1

Its thigh bone (femur) was only 24 millimetres long, making it a very small bird.1

The sternum (breastbone) had a keel along its whole length and two pairs of deep notches at the back edge.1

Vir dino-kenners

Wetenskaplike naam: Parahongshanornis
Benoem deur: Li et al. 20113
Groep: Vroeë voëls
Familie / klade: Hongshanornithidae3
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: Parahongshanornis was named by Li Li, Wang Jingqi, and Hou Shilin in 2011, based on a nearly complete skeleton found near Yuanjiawa, Chaoyang, China.1 2
Steeds omstrede: Scientists are not sure exactly how Parahongshanornis is related to other early birds, because it was assigned to its family based on anatomy rather than a computer analysis.1
