Apatornis
Apatornis was a small, toothed bird that lived in the Late Cretaceous period, about 83.5 million years ago. It was a fast, ground-dwelling hunter that probably chased after small prey. Even though it could fly, it spent much of its time on the ground.12

Datos curiosos
Apatornis had at least one more rib attached to its hip vertebrae than its close relative Ichthyornis, and maybe more, because the whole hip bone wasn't preserved.1
Unlike Ichthyornis, Apatornis did not have ossified tendons covering the top of its sacral region, which is a unique feature.1
The only known fossil of Apatornis is a synsacrum, which is the fused vertebrae over the hips, and it was found in the Smoky Hill Chalk of Kansas.1
Apatornis was originally classified as a species of Ichthyornis, but scientists now think it's more closely related to modern birds.1
The type specimen of Apatornis was discovered by Othniel Charles Marsh in October 1872 at Butte Creek in Kansas.1
Apatornis lived during the Coniacian to Santonian stages, about 89.8 to 83.6 million years ago.2
