The first amber-embedded fossil representing the lizard family Agamidae, Protodraco monocoli gen. et sp. nov., is described in burmite of the lowermost Cenomanian (ca. 99 Ma; mid-Cretaceous) from northern Myanmar. It is among both the oldest known amber lizards and the oldest fossils of the family. The fossil is a well preserved left hind foot with shank, morphologically similar to basal taxa of modern Southeast Asian agamids. Because of the sparse Cretaceous fossil record it could provide a calibration point for divergence-time analyses and contradicts views that agamids colonized SE Asia during the Paleogene.

缅甸北部白垩纪琥珀中的新蜥蜴蜥蜴

最早的琥珀镶嵌化石，代表原蜥蜴纲蜥蜴科的蜥蜴科（Agamidae）。等 缅甸北部最下层的切诺曼尼亚（约99 Ma；白垩纪中期）的煤岩中描述了nov。它是已知的最古老的琥珀蜥蜴和该家庭最古老的化石之一。该化石是保存完好的左小腿，在形态上类似于现代东南亚agamids的基底类群。由于稀少的白垩纪化石记录，它可以为发散时间分析提供校准点，并且与古近纪期间殖民的东南亚的观点相矛盾。
