摘要
Two acrodont iguanians from the Middle Eocene Huadian Formation, Jilin Province, China, highlight the diversity of Acrodonta early in the Tertiary. Because Acrodonta is thought to have been diversifying in the Early Cenozoic, fossils from eastern Asia have great potential to elucidate the evolutionary history of the clade, particularly in combination with molecular-genetic methods. However, the multiplication of new taxon names based only on jaw fragments brings us no closer to this goal. Considerable effort must first be dedicated to the collection and study of modern comparative skeletal material.
