Anqingosaurus brevicephalus is an extinct lizard from the early Middle Paleocene of Anhui, China.[1] A. brevicephalus was originally described as a chameleon, but, not all authorities agree with this.[2] If A. brevicephalus is a chameleon, then Chamaeleonidae fossil record extends all the way into the Paleocene.[citation needed] If it is not, then Chamaeleonidae fossil record starts in the Early Miocene with Chamaeleo caroliquarti.[citation needed]
