1
Eopengornis had special tail feathers with a strong central shaft, called a rachis, which helped it fly and show off.12
2
It belonged to a group of early birds called enantiornithes, which were very common during the time of dinosaurs.1
3
The only known species is called Eopengornis martini.1
4
Its fossils were found in rocks that are about 132 to 125 million years old, from a time called the Hauterivian.5
