Known locations: USA,‭ ‬Montana‭ ‬-‭ ‬Hell Creek Formation,‭ ‬Wyoming‭ ‬-‭ ‬Lance Formation.

       What might have otherwise been an unassuming little lizard,‭ ‬has now become famous worldwide for being named after the‭ ‬44th president of the United States,‭ ‬Barack Obama.‭ ‬The full name Obamadon which means‭ ‬‘Obama tooth‭’ ‬is a reference to‭ ‬Barack Obama’s smile.
       Fossils of Obamadon were originally assigned to Leptochamops denticulatus,‭ ‬but a subsequent review of the fossils brought the realisation that two of the jaw fragments were from a unique and unknown genus.‭ ‬The teeth in the jaws are similar to those of other insectivorous lizards,‭ ‬and comparison to other genera has yielded a rough size estimate of about thirty centimetres long from nose to tail.
       Excluding dinosaurs and pterosaurs,‭ ‬other reptiles associated with the same time and locations as Obamadon include the monitor lizard-like Palaeosaniwa and the snake Cerberophis.
