       The fairly high number of Leptochamops specimens so far found suggests that this would have been a fairly common little lizard in the late Cretaceous ecosystems of North America.‭ ‬Like with many modern lizard today,‭ ‬Leptochamops was probably a fairly small predator of invertebrates while it tried to keep out of the predatory scope of dromaeosaurid dinosaurs such as Saurornitholestes.
       In‭ ‬2012‭ ‬two lower jaw fragments that were previously assigned to the type species L.‭ ‬denticulatus were found to be different.‭ ‬These were used to create a new genus,‭ ‬Obamadon,‭ ‬so named after the‭ ‬44th president of the United States of America,‭ ‬Barack Obama,‭ ‬however the name was not formalised as valid until‭ ‬2013.
