Oculudentavis

Oculudentavis is an extinct genus of lizard of uncertain taxonomic placement, originally but inaccurately identified as an avialan dinosaur (bird, in the broad sense). It contains two known species, O. khaungraae and O. naga. Each species is known from one partial fossil specimen in Burmese amber, which differ in several proportions. Their skulls measure in length, indicating that Oculudentavis would have been comparable in size with the modern bee hummingbird if it were an avialan. Both specimens were retrieved from 99-million-year-old deposits of the Hukawng Basin in Kachin State, northern Myanmar. The type specimen of O. khaungraae is embroiled in controversy regarding its identity and the ethical issues surrounding the acquisition and study of Burmese amber. The original description advocating for an avialan identity was published in Nature, but has since been retracted from the journal.

== Discovery and naming == Oculudentavis khaungraae is known from a complete skull preserved in Burmese amber, found at the Angbamo site in Tanai Township, Kachin State, northern Myanmar. The genus name Oculudentavis was chosen to include the combination of the words oculus, dentes, and avis. These Latin words translate to "eye", "teeth", and "bird" respectively. The specific name honors Khaung Ra, the woman who donated the piece of amber to the Hupoge Amber Museum for study. Presently, the holotype is cataloged as HPG-15-3 in the Hupoge Amber Museum.
