'''''Karakhtia nessovi''''' is a species of proarticulate from the Ediacaran period, around 555 Million Years Ago.

== Discovery and name ==
The holotype fossil of ''Karakhtia'' was found from the Ustʹ Pinega Formation, in the White Sea of Russia, and described in 2004.<ref name=Ivanstov/>
The generic name ''Karakhtia'' is derived from the place name ''Karakhta River'', near to where the fossil material was found. The specific name ''nessovi'' is derived from the surname of ''L.A. Nessov'', a Leningrad paleontologist.<ref name=Ivanstov/>
== Description ==
''Karakhtia nessovi'' is a proarticulate from the Vendiidae family, growing up to {{cvt|100|mm|1}} in length, and like other members of its family, it has a headshield-like structure. Unlike anything seen in other proarticulates, it features a margin with radial folds, giving it a frilly appearance.<ref name=Ivanstov/>
