The right dentary of a new hadrosauroid dinosaur, Penelopognathus
weishampeli, has been discovered in the Bayan Gobi Formation (Albian,
Lower Cretaceous) of Inner Mongolia (P.R. China). This new taxon is
characterised by its elongated, straight dental ramus, whose lateral
side is pierced by about 20 irregularly distributed foramina. Its
dentary teeth appear more primitive than those of Probactrosaurus, but
more advanced than those of Altirhinus, both also from the Lower
Cretaceous of the Gobi area. Non-hadrosaurid Hadrosauroidea were
already well diversified in eastern Asia by Early Cretaceous time,
suggesting an Asian origin for the hadrosauroid clade.
