Jinguofortisidae

Jinguofortisidae is an extinct family of early pygostylian dinosaurs known from the Early Cretaceous. They were found in northern China.

==Description== The Jinguofortisidae are distinguished from other non-ornithothoracine avialans by the following features: the scapula and coracoid fused into a scapulocoracoid; a boomeranged-shaped furcula without a hypocleidium; proximal margin of humerus concave centrally; deltopectoral crest large and not perforated; minor metacarpal markedly bowed caudally; alular digit terminating at the level of the distal end of major metacarpal; and proximal phalanx of the major digit longer than the intermediate phalanx.
