Penelopognathus (meaning "wild duck jaw") is agenus ofhadrosauroiddinosaur which lived in the EarlyCretaceousBayin-Gobi Formation in what is nowChina. The discovery of this taxon contributes to the hypothesis that hadrosauroids originated in Asia.[1] Thetype species,Penelopognathus weishampeli, named afterDavid Weishampel, was described by Godefroit, Li, and Shang in 2005, based on fragmentary jaw fossils.[1]
Its jaw is similar to that ofAltirhinus andProbactrosaurus, suggesting thatPenelopognathus was related to the two genera.[1] Prieto-Márquez and Carrera Farias (2021) found thatTelmatosaurus was the sister taxon toPenelopognathus, which was also found to be closely related toLophorhothon, as opposed toTethyshadros.[2]Penelopognathus grew up to around 5 metres (16 ft) long and around 2 metres (6.6 ft) tall when fully grown.
