Figure 6

The historical biogeography of acrodont lizards based on the molecular, paleontological and geological evidence. Paleogeographical maps at six different times [63] are shown on which a hypothesis on the origin and migration pathways for agamids (red) and chamaeleonids (blue) is illustrated. The earliest fossil records for acrodonts and chameleons are, respectively, Early-Middle Jurassic (165 - 200 MYA) Bharatoagama from the Kota Formation of India [61] and Miocene (~26 MYA) Chamaeleo caroliquarti from Bohemia [64]. Acrodont fossils of Priscagamidae are found from Aptian-Albian (100 - 120 MYA) and Campanian (~80 MYA) Central Asia and Mongolia [43, 54, 55]. Another acrodont fossil of a gliding lizard Xianglong is found from Early Cretaceous of China [56].
