Igama lithetha: “Marsh's neglected bird”1

Yayitya: InyamaIintaka zokuqalaiCretaceous yamva

Iaceornis was a seabird that lived alongside dinosaurs like T. rex. It had strong wings and probably flew over the ancient sea that covered what is now Kansas.1

izinto ezimnandi

Iinyani ezimnandi

Iaceornis lived about 83.5 million years ago during the Late Cretaceous period.1

Only one fossil of Iaceornis has ever been found, and it is a partial skeleton without a skull.1

For over 120 years, scientists thought this fossil belonged to another bird called Apatornis. In 2004, paleontologist Julia Clarke proved it was a different species.1

The name Iaceornis means 'neglected bird' because the fossil was ignored for so long.1

Iaceornis is more advanced than the toothed bird Ichthyornis but less advanced than modern birds.1

The fossil was first dug up by famous fossil hunter Othniel Charles Marsh in 1877.1

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

Ukufunyanwa: The fossil was collected by Othniel Charles Marsh in 1877 in Kansas. It was first thought to be Apatornis celer, but in 2004 Julia Clarke renamed it Iaceornis marshi after studying its wing bones.1
Kusaxoxwa ngayo: Scientists are not sure exactly what Iaceornis looked like because the only fossil is missing its skull.1
