Prettige feite

Longicrusavis had very long legs compared to its arms, which helped it wade in water like a modern heron.1

Its fossil preserves carbonized traces of feathers, showing it had full plumage with visible colouration around the head and forelimbs.1

Longicrusavis had a long, fan-shaped tail that improved its flight, and scientists think it is one of the oldest birds with this type of tail.1

It belonged to a group called Hongshanornithidae, named after the Hongshan culture, one of China's oldest recorded cultures.1

Longicrusavis lived about 122 million years ago during the Early Cretaceous period.1

The only known fossil of Longicrusavis is nearly complete and belongs to an adult individual.1

KI-prent van Longicrusavis — 'n KI-prent van hoe Longicrusavis dalk gelyk het, deur 'n rekenaar gemaak uit wat wetenskaplikes weet. Dit is 'n raaiskoot: die regte dier het dalk anders gelyk, en niemand weet wat sy regte kleure was nie.

Vir dino-kenners

Wetenskaplike naam: Longicrusavis
Benoem deur: O'Connor et al. 20104
Groep: Vroeë voëls
Familie / klade: Hongshanornithidae4
Klassifikasie: Theropoda > Avialae4
Ouderdom van die rotse: 126 tot 120 miljoen jaar (Barremian / Aptian)4
Rotsformasies: Yixian4
Lande: China4
Fossielrekords: 1 in The Paleobiology Database4
Ontdekking: Longicrusavis was named by O'Connor, Gao, and Chiappe in 2010 based on a nearly complete skeleton found at Dawangzhangzi in Liaoning, China.1 3
Steeds omstrede: Scientists are not sure if Longicrusavis had teeth in its upper jaw, because the fossil shows tooth sockets but no teeth are preserved.1
