Eoneophron was a small, feathery dinosaur that lived at the very end of the Cretaceous period. It was an oviraptorosaur, a group of bird-like theropods with beaks instead of teeth. This dinosaur was about the size of a turkey and probably ate plants and small animals.1

酷東西

趣味知識

Eoneophron was named in 2024, making it one of the newest dinosaur discoveries.1

Its fossils were first bought for $5,000 at a commercial sale and then donated to a museum for research.2

Scientists used bone histology, looking at the microscopic structure, to find out that this dinosaur was an adult, not a baby of a bigger relative.1

Eoneophron lived alongside the much larger caenagnathid Anzu wyliei in the same time and place.1

Like other oviraptorosaurs, Eoneophron had a beak without teeth and was covered in feathers.1

The Hell Creek Formation where Eoneophron was found is famous for fossils of Triceratops and Tyrannosaurus rex.1

Yes, Eoneophron was covered in complex feathers, much like modern birds. It was a birdlike dinosaur with wings and a toothless beak.4

?When did Eoneophron live?

發現: The fossil was collected from the Hell Creek Formation in South Dakota and bought by Kyle Atkins-Weltman in 2020. He donated it to the Carnegie Museum of Natural History, and scientists named it Eoneophron infernalis in 2024.2 1
仍有爭議: Scientists are still debating how many different caenagnathid species lived in the Hell Creek Formation, since their fossils are rare and often broken.1
