They come from a team of dinosaurs, likewise called paravian dinosaurs or paraves, characterized by bigger numbers held in the air while strolling. They were non- bird dinosaurs and the tiniest ones to exist. Epidexipteryx stands for the earliest uncovered dinosaurs to have decorative plumes, according to the fossil document.

Summary and Dimension

Just one species of Epidexipteryx is recognized. The scientific name Epidexipteryx hui converts as “Hu’s display screen plume” in honor of paleomammologist Hu Yaoming. The dinosaur is likewise called Hushi Yaolong, which implies “Hu Yaoming’s dragon.”
