Omok language

Omok is an extinct Yukaghir language of Siberia, part of a dialect continuum with two surviving languages, also referred to as an eastern dialect of Tundra Yukaghir. It was last spoken perhaps as late as the 18th century. A wordlist of Omok, as well as its sister language Chuvan, was recorded in 1821 by Fyodor Matyushkin.
