Jinguofortisidae is an extinct family of early birds known from the Early Cretaceous, found in northern China.
Description
Jinguofortisidae is distinguished from other non-ornithothoracine birds 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.[1]
Phylogeny
Wang et al. (2018) erected Jinguofortisidae after finding Chongmingia (previously considered Avebrevicauda incertae sedis by Wang et al. 2016) to be sister to their new taxon Jinguofortis.[1]
