About Eoneophron
What it was like
Eoneophron was a caenagnathid, a toothless, feathered relative of Oviraptor. It is known from a partial hind leg. It was about the size of a person, bigger than some of its close relatives.
Its world
It lived about 72 to 66 million years ago, at the very end of the Late Cretaceous, in what is now South Dakota. Its bones come from the Hell Creek Formation, where it shared the land with Tyrannosaurus, Triceratops and Edmontosaurus.
How it was found
Atkins-Weltman and colleagues named it in 2024. The type species is Eoneophron infernalis. Its name compares it to a kind of vulture.
