Jinguofortis is a genus of primitive avialan bird belonging to the clade Pygostylia that lived during the Valanginian stage of the Early Cretaceous. It was found in the Dabeigou Formation in northeastern China.[1]

Description

Jinguofortis is notable for a mosaic of primitive and advanced characters, including a fused scapulocoracoid and highly reduced manual digits. Differences from Chongmingia include: furcula less robust with a smaller interclavicular angle of 70°; pedal digit I approximately 70% of the length of digit II; and pedal digit II shorter than IV.[1]

Naming

The name Jinguofortis is a combination of jinguo, from Mandarin (巾帼), referring to female warrior, and fortis, Latin for brave.[1]

Classification

Wang et al. (2018) recovered Jinguofortis as a basal pygostylian more derived than Confuciusornithiformes, but more primitive than Sapeornithiformes, and as sister to the previously problematic genus Chongmingia.[1]
