Sinopterus sp.
Middle Jurassic
Tiaojishan Formation
Liaoning
China

A rare complete fossil pterosaur belonging to the flying reptile clade Pterosauria, preserved in full articulation with the skeleton largely intact. Specimens of this quality are highly sought after due to the fragile, hollow-boned nature of pterosaurs, which typically makes complete preservation uncommon.
Complete 11 inch (280mm) complete pterosaur on 18 inch (457mm) slab. Very rare.
