Jinguofortisidae is an extinct family of early
avialans known from the Early Cretaceous
, found in northern China.
Description
The Jinguofortisidae are distinguished from other non-
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.[2]
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.[2]
In 2023, a third jinguofortisid was described by Li et al. They recovered their new taxon,
