Dinosaur Series: Epidexipteryx

The Epidexipteryx (Epidexipteryx hui) is a small pterosaur, a cousin of the dinosaur, in the Scansorioptergidae family. 

Palaeontologists found a partial skeleton, which was from the Middle Jurassic or Upper Jurassic period.

It had four long tail feathers with central, unbranched rachis (spines) and vanes. Modern birds have branched vanes. It also had simpler body feathers than modern-day birds. It had teeth, but only in the front of the jaw, with long front teeth angled forward.


Its tail was not adapted to flight, but it shows that it had very ornamental plumage. 

It measured about 25 centimetres (10 inches) in length. 

The Epidexipteryx is part of an exhibition called “Evolution on the Road to Enlightenment.” The palaeontologist department of the National Museum of Natural History in Paris held the exhibition of dinosaurs from December 2021 to January 2022 in conjuction with the China Light Festival.
