Elsornis

Igama lithetha: “sand bird”1

Yayitya: InyamaIintaka zokuqalaiCretaceous yamva

Elsornis was a bird that lived in the Gobi Desert about 80 million years ago. It might have been flightless, like an ostrich, and used its strong legs to run after small animals and bugs.1 2

izinto ezimnandi

Iinyani ezimnandi

Elsornis had a wishbone filled with air, which is rare among its relatives, the enantiornithean birds.1 2

Its upper arm was much longer than its lower arm, a feature that helps scientists think it could not fly.2

Elsornis is known from a single, well-preserved skeleton that includes many bones like limbs, vertebrae, and ribs.1 2

It lived during the Campanian age of the Late Cretaceous, about 80 million years ago.1 2

Elsornis belongs to a group called Enantiornithes, also known as 'opposite birds', which had a different shoulder joint from modern birds.1 2

If Elsornis could not fly, it would be one of the few flightless birds from the time of dinosaurs.1 2

Umfanekiso owenziwe yi-AI: Elsornis — Umfanekiso owenziwe yi-AI obonisa indlela Elsornis esenokuba wayekhangeleka ngayo, wenziwe yikhompyutha ngokwento eyaziwa zizazinzulu. Kukuqikelela nje: esona silwanyana sinokuba sasikhangeleka ngenye indlela, kwaye akukho mntu waziyo imibala yaso yokwenyani.

ubuzile

Eyona mibuzo ibuzwa kakhulu: Elsornis

?Was Elsornis a dinosaur?

Yes, it was a bird, and birds are a type of dinosaur called avialan theropods.1

?Could Elsornis fly?

Probably not. Scientists think it was flightless or nearly flightless, based on its chest bones.1

It probably ate small animals and bugs, and may have also scavenged dead animals left by other carnivores.1
